902257 ÷ 91 
The aim is to understand the frequency of 91 in 902257.

Step 1:
91 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 91

Let's proceed to step 2:
When dividing 90 by 91, we get 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Fetch the next digit (2) from the dividend, attach it to 90 and continue: 902 / 91

Let's proceed to step 3:
If we divide 902 by 91, we get 9 and a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 83 after subtracting 819 from 902.
Take the next digit (2) from the dividend and append it to 83, then repeat: 832 / 91

On to step 4:
832 divided by 91 is 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 99.0
The remainder is 13 after subtracting 819 from 832.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 91

Step 5:
91 goes into 135 1 times with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 991.0
Deduct 91 from 135 and we're left with 44.
Grab the next digit (7) from the dividend, add it to 44, then carry on: 447 / 91

Moving on to step 6:
91 goes into 447 4 times with a remainder of 83.
The next digit of our result is 4. 
Result so far: 9914.0
If we take 364 away from 447, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 7:
If we divide 830 by 91, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 9914.9
If we subtract 819 from 830, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 8:
When dividing 110 by 91, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 9914.91
If we take 91 away from 110, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
91 goes into 190 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 9914.912
The remainder is 8 after subtracting 182 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
91 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 9914.912
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
The number 91 fits into 800 8 times, leaving a remainder of 72.
The next digit of our result is 8. 
Result so far: 9914.91208
Deduct 728 from 800 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
720 divided by 91 is 7 with a remainder of 83.
The next digit of our result is 7. 
Result so far: 9914.912087
If we take 637 away from 720, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 13:
The number 91 fits into 830 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 9914.9120879
Subtract 819 from 830 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
If we divide 110 by 91, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 9914.91208791
Subtracting 91 from 110 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 9914.91208791 with a remaining 1.9e-08.
