Let's divide 91757 by 17
The aim is to understand the frequency of 17 in 91757.

Moving on to step 1:
17 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 17

Step 2:
If we divide 91 by 17, we get 5 and a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 85 from 91, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 17

On to step 3:
17 goes into 67 3 times with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Deduct 51 from 67 and we're left with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 17

Step 4:
17 can be fit into 165 9 times, resulting in a remainder of 12.
The next digit of our result is 9. 
Result so far: 539.0
Subtracting 153 from 165 leaves us with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 17

Going ahead to step 5:
17 can be fit into 127 7 times, resulting in a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 5397.0
If we take 119 away from 127, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 6:
80 divided by 17 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 5397.4
If we subtract 68 from 80, 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.

Step 7:
120 divided by 17 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 5397.47
If we subtract 119 from 120, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
17 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 5397.47
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
100 divided by 17 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 5397.4705
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
17 can be fit into 150 8 times, resulting in a remainder of 14.
The next digit of our result is 8. 
Result so far: 5397.47058
If we take 136 away from 150, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
The number 17 fits into 140 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 5397.470588
Subtract 136 from 140 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 5397.470588, with a leftover of 4e-07.
