We're dividing 918457 by 91 
The aim is to understand the frequency of 91 in 918457.

On to step 1:
91 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
Subtract 0 from 9 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 91

Going ahead to step 2:
91 divided by 91 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 91 from 91 to get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 91

Advancing to step 3:
91 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 8 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 91

Step 4:
91 can be fit into 84 0 times, resulting in a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
If we subtract 0 from 84, we get 84.
Include the next digit (5) from the dividend after 84, then repeat: 845 / 91

On to step 5:
91 can be fit into 845 9 times, resulting in a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 1009.0
If we subtract 819 from 845, we get 26.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 91

Moving on to step 6:
When dividing 267 by 91, we get 2 with a remainder of 85.
The next digit of our result is 2. 
Result so far: 10092.0
Subtract 182 from 267 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 7:
91 goes into 850 9 times with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 10092.9
If we subtract 819 from 850, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
91 goes into 310 3 times with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 10092.93
The remainder is 37 after subtracting 273 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
91 goes into 370 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 10092.934
The remainder is 6 after subtracting 364 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
When dividing 60 by 91, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10092.934
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
The number 91 fits into 600 6 times, leaving a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 10092.93406
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
91 goes into 540 5 times with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 10092.934065
The remainder is 85 after subtracting 455 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 13:
When dividing 850 by 91, we get 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 10092.9340659
If we subtract 819 from 850, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 14:
If we divide 310 by 91, we get 3 and a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 10092.93406593
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Our division results in 10092.93406593 with a remaining 3.7e-08.
