845103 ÷ 91 
The aim is to understand the frequency of 91 in 845103.

Advancing to step 1:
8 divided by 91 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 91

On to step 2:
84 divided by 91 is 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Grab the next digit (5) from the dividend, add it to 84, then carry on: 845 / 91

Going ahead to step 3:
91 goes into 845 9 times with a remainder of 26.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 819 from 845 to get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 91

Step 4:
91 can be fit into 261 2 times, resulting in a remainder of 79.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
If we take 182 away from 261, we end up with 79.
Fetch the next digit (0) from the dividend, attach it to 79 and continue: 790 / 91

Going ahead to step 5:
When dividing 790 by 91, we get 8 with a remainder of 62.
The next digit of our result is 8. 
Result so far: 928.0
Subtract 728 from 790 to get 62.
Take the next digit (3) from the dividend and append it to 62, then repeat: 623 / 91

Advancing to step 6:
When dividing 623 by 91, we get 6 with a remainder of 77.
Write down 6 as next digit of the result. 
Result so far: 9286.0
If we take 546 away from 623, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 7:
770 divided by 91 is 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 9286.8
Deduct 728 from 770 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
91 can be fit into 420 4 times, resulting in a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 9286.84
Subtracting 364 from 420 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.

Advancing to step 9:
If we divide 560 by 91, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 9286.846
If we take 546 away from 560, 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.

On to step 10:
The number 91 fits into 140 1 times, leaving a remainder of 49.
The next digit of our result is 1. 
Result so far: 9286.8461
Deduct 91 from 140 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 11:
91 goes into 490 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 9286.84615
The remainder is 35 after subtracting 455 from 490.
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 12:
When dividing 350 by 91, we get 3 with a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 9286.846153
The remainder is 77 after subtracting 273 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 13:
When dividing 770 by 91, we get 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 9286.8461538
The remainder is 42 after subtracting 728 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
If we divide 420 by 91, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 9286.84615384
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.

After the division, we end up with 9286.84615384 and a remainder of 5.6e-08.
