830062 ÷ 91 
The aim is to understand the frequency of 91 in 830062.

Advancing to step 1:
When dividing 8 by 91, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 91

Let's proceed to step 2:
When dividing 83 by 91, we get 0 with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Append the next digit (0) from the dividend to 83 and continue with: 830 / 91

Moving on to step 3:
The number 91 fits into 830 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 819 from 830, we get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 91

Step 4:
110 divided by 91 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Subtracting 91 from 110 leaves us with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 91

On to step 5:
If we divide 196 by 91, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 912.0
If we take 182 away from 196, we end up with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 91

Step 6:
142 divided by 91 is 1 with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 9121.0
Subtract 91 from 142 to 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 7:
91 can be fit into 510 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 9121.5
The remainder is 55 after subtracting 455 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 8:
550 divided by 91 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 9121.56
Subtract 546 from 550 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
91 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 9121.56
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 10:
If we divide 400 by 91, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 9121.5604
The remainder is 36 after subtracting 364 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
The number 91 fits into 360 3 times, leaving a remainder of 87.
Write down 3 as next digit of the result. 
Result so far: 9121.56043
Subtracting 273 from 360 leaves us 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 12:
If we divide 870 by 91, we get 9 and a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 9121.560439
Subtracting 819 from 870 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 13:
The number 91 fits into 510 5 times, leaving a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 9121.5604395
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.

On to step 14:
91 can be fit into 550 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 9121.56043956
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.

After the division, we end up with 9121.56043956 and a remainder of 4e-09.
