928165 divided by 91 
The aim is to understand the frequency of 91 in 928165.

Step 1:
91 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 91

Advancing to step 2:
When dividing 92 by 91, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 91 from 92 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 91

Step 3:
91 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 18, we end up with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 91

Going ahead to step 4:
91 goes into 181 1 times with a remainder of 90.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
The remainder is 90 after subtracting 91 from 181.
Grab the next digit (6) from the dividend, add it to 90, then carry on: 906 / 91

Going ahead to step 5:
If we divide 906 by 91, we get 9 and a remainder of 87.
Record the quotient 9 as the next digit in the result. 
Result so far: 1019.0
Subtracting 819 from 906 leaves us with 87.
Append the next digit (5) from the dividend to 87 and continue with: 875 / 91

Advancing to step 6:
When dividing 875 by 91, we get 9 with a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 10199.0
Subtracting 819 from 875 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 7:
91 goes into 560 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 10199.6
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
140 divided by 91 is 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 10199.61
The remainder is 49 after subtracting 91 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
91 goes into 490 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 10199.615
If we take 455 away from 490, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 10:
91 can be fit into 350 3 times, resulting in a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 10199.6153
If we subtract 273 from 350, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 11:
The number 91 fits into 770 8 times, leaving a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 10199.61538
If we subtract 728 from 770, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
91 can be fit into 420 4 times, resulting in a remainder of 56.
The next digit of our result is 4. 
Result so far: 10199.615384
The remainder is 56 after subtracting 364 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
The number 91 fits into 560 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 10199.6153846
Subtract 546 from 560 to get 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 14:
If we divide 140 by 91, we get 1 and a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 10199.61538461
If we subtract 91 from 140, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The quotient of the division is 10199.61538461, and the remainder is 4.9e-08.
