170708 divided by 91 
Let's see how many times 91 fits into 170708.

Let's proceed to step 1:
91 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 91

Moving on to step 2:
When dividing 17 by 91, we get 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 91

Let's proceed to step 3:
The number 91 fits into 170 1 times, leaving a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 91 from 170 to get 79.
Bring next digit (7) of the dividend behind the 79 and repeat the process: 797 / 91

On to step 4:
The number 91 fits into 797 8 times, leaving a remainder of 69.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 728 from 797 to get 69.
Include the next digit (0) from the dividend after 69, then repeat: 690 / 91

Step 5:
690 divided by 91 is 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 187.0
Subtract 637 from 690 to get 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 91

Advancing to step 6:
91 can be fit into 538 5 times, resulting in a remainder of 83.
Put 5 as the next digit of the answer. 
Result so far: 1875.0
Subtract 455 from 538 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 7:
91 goes into 830 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 1875.9
Deduct 819 from 830 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
110 divided by 91 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1875.91
The remainder is 19 after subtracting 91 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
190 divided by 91 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 1875.912
The remainder is 8 after subtracting 182 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 91 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 1875.912
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
When dividing 800 by 91, we get 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 1875.91208
If we subtract 728 from 800, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
The number 91 fits into 720 7 times, leaving a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 1875.912087
Deduct 637 from 720 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 13:
If we divide 830 by 91, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 1875.9120879
Subtracting 819 from 830 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
91 goes into 110 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1875.91208791
Deduct 91 from 110 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 1875.91208791 with a remainder of 1.9e-08.
