We divide 170657 by 91
We want to divide 170657 by 91.

On to step 1:
The number 91 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 91

Step 2:
The number 91 fits into 17 0 times, leaving a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 91

Step 3:
91 can be fit into 170 1 times, resulting in a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 91 from 170 leaves us with 79.
Include the next digit (6) from the dividend after 79, then repeat: 796 / 91

Step 4:
When dividing 796 by 91, we get 8 with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 68 after subtracting 728 from 796.
Append the next digit (5) from the dividend to 68 and continue with: 685 / 91

Let's proceed to step 5:
685 divided by 91 is 7 with a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 187.0
If we take 637 away from 685, we end up with 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 91

On to step 6:
The number 91 fits into 487 5 times, leaving a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 1875.0
If we take 455 away from 487, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
The number 91 fits into 320 3 times, leaving a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 1875.3
Deduct 273 from 320 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 8:
91 goes into 470 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1875.35
The remainder is 15 after subtracting 455 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
91 goes into 150 1 times with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 1875.351
Subtracting 91 from 150 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 10:
When dividing 590 by 91, we get 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 1875.3516
If we subtract 546 from 590, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
91 goes into 440 4 times with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 1875.35164
If we take 364 away from 440, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
When dividing 760 by 91, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 1875.351648
The remainder is 32 after subtracting 728 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
320 divided by 91 is 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 1875.3516483
Subtracting 273 from 320 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 14:
If we divide 470 by 91, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1875.35164835
The remainder is 15 after subtracting 455 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 1875.35164835 with a remaining 1.5e-08.
