Let's divide 101357 by 91
The aim is to understand the frequency of 91 in 101357.

Going ahead to step 1:
91 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 91

Going ahead to step 2:
When dividing 10 by 91, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 91

Advancing to step 3:
If we divide 101 by 91, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 91 from 101 and we're left with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 91

Step 4:
91 can be fit into 103 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 91 from 103, we get 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 91

Advancing to step 5:
91 can be fit into 125 1 times, resulting in a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 111.0
If we subtract 91 from 125, we get 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 91

On to step 6:
91 can be fit into 347 3 times, resulting in a remainder of 74.
The number 3 becomes the next digit in our result. 
Result so far: 1113.0
If we take 273 away from 347, 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.

Let's proceed to step 7:
When dividing 740 by 91, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1113.8
If we take 728 away from 740, we end up with 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 8:
If we divide 120 by 91, we get 1 and a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1113.81
The remainder is 29 after subtracting 91 from 120.
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 9:
The number 91 fits into 290 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 1113.813
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
If we divide 170 by 91, we get 1 and a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 1113.8131
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.

Moving on to step 11:
When dividing 790 by 91, we get 8 with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 1113.81318
If we take 728 away from 790, we end up 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.

On to step 12:
91 goes into 620 6 times with a remainder of 74.
The next digit of our result is 6. 
Result so far: 1113.813186
Deduct 546 from 620 and we're left 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.

Advancing to step 13:
If we divide 740 by 91, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 1113.8131868
The remainder is 12 after subtracting 728 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
91 goes into 120 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1113.81318681
If we subtract 91 from 120, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 1113.81318681, and the remainder is 2.9e-08.
