625636 divided by 40 
Our goal is to divide 625636 by 40.

On to step 1:
The number 40 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 40

Advancing to step 2:
The number 40 fits into 62 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 40 from 62 to get 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 40

Going ahead to step 3:
The number 40 fits into 225 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 25 after subtracting 200 from 225.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 40

On to step 4:
256 divided by 40 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 156.0
If we subtract 240 from 256, we get 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 40

Moving on to step 5:
If we divide 163 by 40, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 1564.0
If we subtract 160 from 163, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 40

Moving on to step 6:
36 divided by 40 is 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 15640.0
Subtracting 0 from 36 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
360 divided by 40 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 15640.9
Deduct 360 from 360 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.

On to step 8:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15640.9
If we subtract 0 from 0, we 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 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 15640.9
Subtracting 0 from 0 leaves us 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.

Our division results in 15640.9 with a remaining 0.0.
