We're dividing 91083932 by 921 
The aim is to understand the frequency of 921 in 91083932.

Moving on to step 1:
921 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 921

On to step 2:
91 divided by 921 is 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Bring next digit (0) of the dividend behind the 91 and repeat the process: 910 / 921

On to step 3:
921 can be fit into 910 0 times, resulting in a remainder of 910.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 910, we get 910.
Include the next digit (8) from the dividend after 910, then repeat: 9108 / 921

Advancing to step 4:
If we divide 9108 by 921, we get 9 and a remainder of 819.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 8289 away from 9108, we end up with 819.
Take the next digit (3) from the dividend and append it to 819, then repeat: 8193 / 921

Going ahead to step 5:
921 goes into 8193 8 times with a remainder of 825.
The next digit of our result is 8. 
Result so far: 98.0
Deduct 7368 from 8193 and we're left with 825.
Grab the next digit (9) from the dividend, add it to 825, then carry on: 8259 / 921

Let's proceed to step 6:
When dividing 8259 by 921, we get 8 with a remainder of 891.
The next digit of our result is 8. 
Result so far: 988.0
Deduct 7368 from 8259 and we're left with 891.
Fetch the next digit (3) from the dividend, attach it to 891 and continue: 8913 / 921

On to step 7:
When dividing 8913 by 921, we get 9 with a remainder of 624.
Write down 9 as next digit of the result. 
Result so far: 9889.0
Deduct 8289 from 8913 and we're left with 624.
Append the next digit (2) from the dividend to 624 and continue with: 6242 / 921

Let's proceed to step 8:
921 goes into 6242 6 times with a remainder of 716.
Use 6 as the next digit of our solution. 
Result so far: 98896.0
Deduct 5526 from 6242 and we're left with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Step 9:
If we divide 7160 by 921, we get 7 and a remainder of 713.
Write down 7 as next digit of the result. 
Result so far: 98896.7
If we take 6447 away from 7160, we end up with 713.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7130, and continue the process.

Let's proceed to step 10:
7130 divided by 921 is 7 with a remainder of 683.
Record the quotient 7 as the next digit in the result. 
Result so far: 98896.77
Subtract 6447 from 7130 to get 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Our division results in 98896.77 with a remaining 0.683.
