We're dividing 932402 by 91 
The aim is to understand the frequency of 91 in 932402.

On to step 1:
9 divided by 91 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 91

Step 2:
If we divide 93 by 91, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 91 from 93 leaves us with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 91

Going ahead to step 3:
91 goes into 22 0 times with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 22 leaves us with 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 91

Advancing to step 4:
If we divide 224 by 91, we get 2 and a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 102.0
The remainder is 42 after subtracting 182 from 224.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 91

On to step 5:
When dividing 420 by 91, we get 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 1024.0
If we subtract 364 from 420, we get 56.
Append the next digit (2) from the dividend to 56 and continue with: 562 / 91

Going ahead to step 6:
The number 91 fits into 562 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 10246.0
Subtract 546 from 562 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
91 can be fit into 160 1 times, resulting in a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 10246.1
Subtract 91 from 160 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 8:
When dividing 690 by 91, we get 7 with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 10246.17
Subtracting 637 from 690 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 9:
530 divided by 91 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 10246.175
If we take 455 away from 530, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 10:
If we divide 750 by 91, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 10246.1758
If we subtract 728 from 750, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
When dividing 220 by 91, we get 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 10246.17582
Subtract 182 from 220 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
380 divided by 91 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 10246.175824
Deduct 364 from 380 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
91 goes into 160 1 times with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 10246.1758241
The remainder is 69 after subtracting 91 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 14:
690 divided by 91 is 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 10246.17582417
Subtracting 637 from 690 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final result is 10246.17582417 with a remainder of 5.3e-08.
