We divide 637730 by 40
We want to divide 637730 by 40.

Let's proceed to step 1:
If we divide 6 by 40, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 40

Step 2:
If we divide 63 by 40, we get 1 and a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 40 from 63 and we're left with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 40

On to step 3:
If we divide 237 by 40, we get 5 and a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 200 away from 237, we end up with 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 40

Let's proceed to step 4:
The number 40 fits into 377 9 times, leaving a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 159.0
If we take 360 away from 377, we end up with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 40

Moving on to step 5:
When dividing 173 by 40, we get 4 with a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 1594.0
Subtract 160 from 173 to get 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 40

Moving on to step 6:
When dividing 130 by 40, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 15943.0
Subtracting 120 from 130 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
40 goes into 100 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 15943.2
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15943.25
If we take 200 away from 200, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 40 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15943.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 40 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15943.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 15943.25 with a balance of 0.0.
