746113 ÷ 91 
The aim is to understand the frequency of 91 in 746113.

On to step 1:
If we divide 7 by 91, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 91

Moving on to step 2:
The number 91 fits into 74 0 times, leaving a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Bring next digit (6) of the dividend behind the 74 and repeat the process: 746 / 91

On to step 3:
91 goes into 746 8 times with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 18 after subtracting 728 from 746.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 91

Moving on to step 4:
91 can be fit into 181 1 times, resulting in a remainder of 90.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we take 91 away from 181, we end up with 90.
Include the next digit (1) from the dividend after 90, then repeat: 901 / 91

Advancing to step 5:
When dividing 901 by 91, we get 9 with a remainder of 82.
Put 9 as the next digit of the answer. 
Result so far: 819.0
Subtract 819 from 901 to get 82.
Take the next digit (3) from the dividend and append it to 82, then repeat: 823 / 91

Moving on to step 6:
If we divide 823 by 91, we get 9 and a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 8199.0
The remainder is 4 after subtracting 819 from 823.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
When dividing 40 by 91, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8199.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
When dividing 400 by 91, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 8199.04
If we subtract 364 from 400, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
360 divided by 91 is 3 with a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 8199.043
If we take 273 away from 360, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 10:
If we divide 870 by 91, we get 9 and a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 8199.0439
If we subtract 819 from 870, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 11:
91 goes into 510 5 times with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 8199.04395
If we take 455 away from 510, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 12:
550 divided by 91 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 8199.043956
Deduct 546 from 550 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
91 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8199.043956
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
When dividing 400 by 91, we get 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 8199.04395604
If we subtract 364 from 400, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 8199.04395604 with a remaining 3.6e-08.
