Let's divide 38523166 by 640
Our goal is to divide 38523166 by 640.

Advancing to step 1:
The number 640 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 640

On to step 2:
The number 640 fits into 38 0 times, leaving a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 640

Advancing to step 3:
The number 640 fits into 385 0 times, leaving a remainder of 385.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 385, we end up with 385.
Fetch the next digit (2) from the dividend, attach it to 385 and continue: 3852 / 640

Going ahead to step 4:
640 goes into 3852 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 3840 from 3852 and we're left with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 640

On to step 5:
When dividing 123 by 640, we get 0 with a remainder of 123.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
Subtract 0 from 123 to get 123.
Fetch the next digit (1) from the dividend, attach it to 123 and continue: 1231 / 640

On to step 6:
The number 640 fits into 1231 1 times, leaving a remainder of 591.
The next digit of our result is 1. 
Result so far: 601.0
The remainder is 591 after subtracting 640 from 1231.
Bring next digit (6) of the dividend behind the 591 and repeat the process: 5916 / 640

Going ahead to step 7:
If we divide 5916 by 640, we get 9 and a remainder of 156.
Write down 9 as next digit of the result. 
Result so far: 6019.0
If we take 5760 away from 5916, we end up with 156.
Bring next digit (6) of the dividend behind the 156 and repeat the process: 1566 / 640

Moving on to step 8:
640 can be fit into 1566 2 times, resulting in a remainder of 286.
Write down 2 as next digit of the result. 
Result so far: 60192.0
If we take 1280 away from 1566, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 9:
If we divide 2860 by 640, we get 4 and a remainder of 300.
The next digit of our result is 4. 
Result so far: 60192.4
If we subtract 2560 from 2860, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 10:
If we divide 3000 by 640, we get 4 and a remainder of 440.
The number 4 becomes the next digit in our result. 
Result so far: 60192.44
Subtracting 2560 from 3000 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final outcome is 60192.44, with a leftover of 0.44.
