91339200 divided by 257 
Our goal is to divide 91339200 by 257.

Going ahead to step 1:
9 divided by 257 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 257

On to step 2:
91 divided by 257 is 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Bring next digit (3) of the dividend behind the 91 and repeat the process: 913 / 257

Going ahead to step 3:
257 can be fit into 913 3 times, resulting in a remainder of 142.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 771 from 913 leaves us with 142.
Include the next digit (3) from the dividend after 142, then repeat: 1423 / 257

Moving on to step 4:
When dividing 1423 by 257, we get 5 with a remainder of 138.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 1285 from 1423, we get 138.
Take the next digit (9) from the dividend and append it to 138, then repeat: 1389 / 257

Moving on to step 5:
1389 divided by 257 is 5 with a remainder of 104.
Use 5 as the next digit of our solution. 
Result so far: 355.0
If we subtract 1285 from 1389, we get 104.
Fetch the next digit (2) from the dividend, attach it to 104 and continue: 1042 / 257

Advancing to step 6:
257 goes into 1042 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 3554.0
If we take 1028 away from 1042, we end up with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 257

Going ahead to step 7:
257 can be fit into 140 0 times, resulting in a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 35540.0
Subtracting 0 from 140 leaves us with 140.
Grab the next digit (0) from the dividend, add it to 140, then carry on: 1400 / 257

Let's proceed to step 8:
When dividing 1400 by 257, we get 5 with a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 355405.0
The remainder is 115 after subtracting 1285 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 9:
The number 257 fits into 1150 4 times, leaving a remainder of 122.
Put 4 as the next digit of the answer. 
Result so far: 355405.4
The remainder is 122 after subtracting 1028 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 10:
1220 divided by 257 is 4 with a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 355405.44
If we take 1028 away from 1220, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

After the division, we end up with 355405.44 and a remainder of 0.192.
