We divide 983730 by 91
The aim is to understand the frequency of 91 in 983730.

Moving on to step 1:
91 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 91

Let's proceed to step 2:
When dividing 98 by 91, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 91 away from 98, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 91

Moving on to step 3:
When dividing 73 by 91, we get 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 73 after subtracting 0 from 73.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 91

Moving on to step 4:
When dividing 737 by 91, we get 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
If we subtract 728 from 737, we get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 91

Advancing to step 5:
The number 91 fits into 93 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1081.0
Subtract 91 from 93 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 91

Step 6:
91 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10810.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
91 goes into 200 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 10810.2
If we subtract 182 from 200, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
91 can be fit into 180 1 times, resulting in a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 10810.21
The remainder is 89 after subtracting 91 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 9:
When dividing 890 by 91, we get 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 10810.219
If we take 819 away from 890, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 10:
91 can be fit into 710 7 times, resulting in a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 10810.2197
The remainder is 73 after subtracting 637 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 11:
The number 91 fits into 730 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 10810.21978
Deduct 728 from 730 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
When dividing 20 by 91, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10810.21978
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
91 goes into 200 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 10810.2197802
Subtract 182 from 200 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
91 goes into 180 1 times with a remainder of 89.
The next digit of our result is 1. 
Result so far: 10810.21978021
Subtracting 91 from 180 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

The final outcome is 10810.21978021, with a leftover of 8.9e-08.
