We look at the division of 91937053 by 256 
We want to figure out the number of times 91937053 can be divided by 256.

On to step 1:
9 divided by 256 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 256

Advancing to step 2:
256 can be fit into 91 0 times, resulting in a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Grab the next digit (9) from the dividend, add it to 91, then carry on: 919 / 256

Moving on to step 3:
When dividing 919 by 256, we get 3 with a remainder of 151.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 768 away from 919, we end up with 151.
Append the next digit (3) from the dividend to 151 and continue with: 1513 / 256

On to step 4:
1513 divided by 256 is 5 with a remainder of 233.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 233 after subtracting 1280 from 1513.
Take the next digit (7) from the dividend and append it to 233, then repeat: 2337 / 256

Moving on to step 5:
256 goes into 2337 9 times with a remainder of 33.
The next digit of our result is 9. 
Result so far: 359.0
Deduct 2304 from 2337 and we're left with 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 256

Step 6:
If we divide 330 by 256, we get 1 and a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 3591.0
If we subtract 256 from 330, we get 74.
Grab the next digit (5) from the dividend, add it to 74, then carry on: 745 / 256

Moving on to step 7:
256 can be fit into 745 2 times, resulting in a remainder of 233.
The next digit of our result is 2. 
Result so far: 35912.0
Deduct 512 from 745 and we're left with 233.
Grab the next digit (3) from the dividend, add it to 233, then carry on: 2333 / 256

Moving on to step 8:
256 goes into 2333 9 times with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 359129.0
If we take 2304 away from 2333, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
When dividing 290 by 256, we get 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 359129.1
Subtract 256 from 290 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
The number 256 fits into 340 1 times, leaving a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 359129.11
If we subtract 256 from 340, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 359129.11 with a remainder of 0.084.
