We divide 637342 by 40
Our goal is to divide 637342 by 40.

Advancing to step 1:
40 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 40

Let's proceed to step 2:
The number 40 fits into 63 1 times, leaving a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 23 after subtracting 40 from 63.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 40

Going ahead to step 3:
40 can be fit into 237 5 times, resulting in a remainder of 37.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 200 from 237 to get 37.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 40

Let's proceed to step 4:
40 can be fit into 373 9 times, resulting in a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 159.0
If we take 360 away from 373, we end up with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 40

Let's proceed to step 5:
When dividing 134 by 40, we get 3 with a remainder of 14.
The next digit of our result is 3. 
Result so far: 1593.0
Deduct 120 from 134 and we're left with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 40

Let's proceed to step 6:
If we divide 142 by 40, we get 3 and a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 15933.0
Subtract 120 from 142 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
The number 40 fits into 220 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 15933.5
Subtracting 200 from 220 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
40 goes into 200 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15933.55
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 15933.55 with a remainder of 0.0.
