We're dividing 470740 by 91 
The aim is to understand the frequency of 91 in 470740.

Let's proceed to step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 91

Moving on to step 2:
91 can be fit into 47 0 times, resulting in a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 91

Moving on to step 3:
The number 91 fits into 470 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 455 from 470 leaves us with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 91

On to step 4:
If we divide 157 by 91, we get 1 and a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Deduct 91 from 157 and we're left with 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 91

On to step 5:
664 divided by 91 is 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 517.0
Deduct 637 from 664 and we're left with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 91

Advancing to step 6:
91 can be fit into 270 2 times, resulting in a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 5172.0
Subtract 182 from 270 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 7:
When dividing 880 by 91, we get 9 with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 5172.9
Subtracting 819 from 880 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 8:
When dividing 610 by 91, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 5172.96
Subtracting 546 from 610 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
The number 91 fits into 640 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 5172.967
The remainder is 3 after subtracting 637 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
30 divided by 91 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 5172.967
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
When dividing 300 by 91, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 5172.96703
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
If we divide 270 by 91, we get 2 and a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 5172.967032
Subtracting 182 from 270 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 13:
If we divide 880 by 91, we get 9 and a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 5172.9670329
If we subtract 819 from 880, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 14:
610 divided by 91 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 5172.96703296
If we subtract 546 from 610, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 5172.96703296 with a remainder of 6.4e-08.
