We look at the division of 170108 by 91 
We want to divide 170108 by 91.

Moving on to step 1:
1 divided by 91 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 91

Going ahead to step 2:
If we divide 17 by 91, we get 0 and a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 91

Moving on to step 3:
91 goes into 170 1 times with a remainder of 79.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 91 from 170 leaves us with 79.
Take the next digit (1) from the dividend and append it to 79, then repeat: 791 / 91

Going ahead to step 4:
91 goes into 791 8 times with a remainder of 63.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 63 after subtracting 728 from 791.
Include the next digit (0) from the dividend after 63, then repeat: 630 / 91

Advancing to step 5:
If we divide 630 by 91, we get 6 and a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 186.0
The remainder is 84 after subtracting 546 from 630.
Bring next digit (8) of the dividend behind the 84 and repeat the process: 848 / 91

Advancing to step 6:
When dividing 848 by 91, we get 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 1869.0
Deduct 819 from 848 and we're left 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.

Advancing to step 7:
If we divide 290 by 91, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 1869.3
Subtracting 273 from 290 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
When dividing 170 by 91, we get 1 with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 1869.31
Subtract 91 from 170 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 9:
91 can be fit into 790 8 times, resulting in a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 1869.318
Deduct 728 from 790 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
620 divided by 91 is 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 1869.3186
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 11:
740 divided by 91 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1869.31868
If we subtract 728 from 740, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
If we divide 120 by 91, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1869.318681
If we take 91 away from 120, 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.

Let's proceed to step 13:
When dividing 290 by 91, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 1869.3186813
Subtract 273 from 290 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 14:
The number 91 fits into 170 1 times, leaving a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 1869.31868131
If we subtract 91 from 170, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The final result is 1869.31868131 with a remainder of 7.9e-08.
