We divide 476497 by 91
The aim is to understand the frequency of 91 in 476497.

On to step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 91

Advancing to step 2:
47 divided by 91 is 0 with a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 47 leaves us with 47.
Grab the next digit (6) from the dividend, add it to 47, then carry on: 476 / 91

Let's proceed to step 3:
91 goes into 476 5 times with a remainder of 21.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 21 after subtracting 455 from 476.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 91

Moving on to step 4:
When dividing 214 by 91, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 52.0
Deduct 182 from 214 and we're left with 32.
Take the next digit (9) from the dividend and append it to 32, then repeat: 329 / 91

Going ahead to step 5:
When dividing 329 by 91, we get 3 with a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 523.0
The remainder is 56 after subtracting 273 from 329.
Include the next digit (7) from the dividend after 56, then repeat: 567 / 91

Step 6:
When dividing 567 by 91, we get 6 with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 5236.0
The remainder is 21 after subtracting 546 from 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
When dividing 210 by 91, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 5236.2
The remainder is 28 after subtracting 182 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
When dividing 280 by 91, we get 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 5236.23
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
91 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 5236.23
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
If we divide 700 by 91, we get 7 and a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 5236.2307
If we take 637 away from 700, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 11:
91 can be fit into 630 6 times, resulting in a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 5236.23076
If we subtract 546 from 630, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
840 divided by 91 is 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 5236.230769
If we take 819 away from 840, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 13:
If we divide 210 by 91, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 5236.2307692
The remainder is 28 after subtracting 182 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
The number 91 fits into 280 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 5236.23076923
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 5236.23076923 and a remainder of 7e-09.
