Kumon Long Division Method [top] -

Before Level D (where long division is focused), students must demonstrate speed and accuracy in vertical subtraction with borrowing and multi-digit multiplication.

Timing is crucial. Kumon suggests that a Level D student should finish 20 long division problems in 10–15 minutes. Speed comes from mental math—not counting on fingers. kumon long division method

Multiply the quotient digit (2) by the divisor (3): 2 × 3 = 6. Write the 6 under the 8. Subtract: 8 − 6 = 2.

The Kumon long division method is designed to help students develop a deep understanding of the division process, rather than just memorizing procedures. This approach is based on the following principles:

Some parents ask: "Why learn long division when phones have calculators?" Speed comes from mental math—not counting on fingers

And that confidence? It carries forward—all the way to calculus and beyond.

The Kumon method teaches the famous acronym (Divide, Multiply, Subtract, Bring Down), but with a unique twist: every step is verbalized and written in a specific color-coded or spatial format to reduce errors.
