We're dividing 91573182 by 257 
Let's see how many times 257 fits into 91573182.

Going ahead to step 1:
The number 257 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 257

Moving on to step 2:
The number 257 fits into 91 0 times, leaving 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.
Include the next digit (5) from the dividend after 91, then repeat: 915 / 257

Going ahead to step 3:
When dividing 915 by 257, we get 3 with a remainder of 144.
The next digit of our result is 3. 
Result so far: 3.0
If we take 771 away from 915, we end up with 144.
Fetch the next digit (7) from the dividend, attach it to 144 and continue: 1447 / 257

Moving on to step 4:
When dividing 1447 by 257, we get 5 with a remainder of 162.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtracting 1285 from 1447 leaves us with 162.
Bring next digit (3) of the dividend behind the 162 and repeat the process: 1623 / 257

Step 5:
257 can be fit into 1623 6 times, resulting in a remainder of 81.
Write down 6 as next digit of the result. 
Result so far: 356.0
Deduct 1542 from 1623 and we're left with 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 257

On to step 6:
257 goes into 811 3 times with a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 3563.0
If we take 771 away from 811, we end up with 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 257

Moving on to step 7:
When dividing 408 by 257, we get 1 with a remainder of 151.
The number 1 becomes the next digit in our result. 
Result so far: 35631.0
If we subtract 257 from 408, we get 151.
Grab the next digit (2) from the dividend, add it to 151, then carry on: 1512 / 257

Moving on to step 8:
If we divide 1512 by 257, we get 5 and a remainder of 227.
The number 5 becomes the next digit in our result. 
Result so far: 356315.0
If we take 1285 away from 1512, we end up with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Moving on to step 9:
257 goes into 2270 8 times with a remainder of 214.
Record the quotient 8 as the next digit in the result. 
Result so far: 356315.8
Subtract 2056 from 2270 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 10:
257 goes into 2140 8 times with a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 356315.88
Subtract 2056 from 2140 to 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 outcome is 356315.88, with a leftover of 0.084.
