Let's divide 91705451 by 255
We want to figure out the number of times 91705451 can be divided by 255.

Step 1:
If we divide 9 by 255, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 255

Going ahead to step 2:
91 divided by 255 is 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Take the next digit (7) from the dividend and append it to 91, then repeat: 917 / 255

Advancing to step 3:
255 goes into 917 3 times with a remainder of 152.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 765 from 917 and we're left with 152.
Grab the next digit (0) from the dividend, add it to 152, then carry on: 1520 / 255

On to step 4:
255 goes into 1520 5 times with a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 1275 from 1520 and we're left with 245.
Include the next digit (5) from the dividend after 245, then repeat: 2455 / 255

Moving on to step 5:
255 goes into 2455 9 times with a remainder of 160.
Put 9 as the next digit of the answer. 
Result so far: 359.0
If we subtract 2295 from 2455, we get 160.
Append the next digit (4) from the dividend to 160 and continue with: 1604 / 255

Moving on to step 6:
255 can be fit into 1604 6 times, resulting in a remainder of 74.
The next digit of our result is 6. 
Result so far: 3596.0
Subtract 1530 from 1604 to get 74.
Grab the next digit (5) from the dividend, add it to 74, then carry on: 745 / 255

On to step 7:
745 divided by 255 is 2 with a remainder of 235.
The next digit of our result is 2. 
Result so far: 35962.0
Subtracting 510 from 745 leaves us with 235.
Include the next digit (1) from the dividend after 235, then repeat: 2351 / 255

Let's proceed to step 8:
When dividing 2351 by 255, we get 9 with a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 359629.0
If we subtract 2295 from 2351, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
255 can be fit into 560 2 times, resulting in a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 359629.2
The remainder is 50 after subtracting 510 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
500 divided by 255 is 1 with a remainder of 245.
Write down 1 as next digit of the result. 
Result so far: 359629.21
Subtract 255 from 500 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 11:
255 goes into 2450 9 times with a remainder of 155.
Record the quotient 9 as the next digit in the result. 
Result so far: 359629.219
Subtract 2295 from 2450 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 12:
If we divide 1550 by 255, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 359629.2196
Subtract 1530 from 1550 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
When dividing 200 by 255, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 359629.2196
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 14:
255 can be fit into 2000 7 times, resulting in a remainder of 215.
The next digit of our result is 7. 
Result so far: 359629.219607
Deduct 1785 from 2000 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 15:
255 can be fit into 2150 8 times, resulting in a remainder of 110.
Use 8 as the next digit of our solution. 
Result so far: 359629.2196078
Subtract 2040 from 2150 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 16:
When dividing 1100 by 255, we get 4 with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 359629.21960784
The remainder is 80 after subtracting 1020 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 359629.21960784, and the remainder is 8e-08.
