Let's divide 12256534 by 921
The aim is to understand the frequency of 921 in 12256534.

Step 1:
When dividing 1 by 921, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 921

Going ahead to step 2:
When dividing 12 by 921, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 921

Advancing to step 3:
If we divide 122 by 921, we get 0 and a remainder of 122.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 122 after subtracting 0 from 122.
Grab the next digit (5) from the dividend, add it to 122, then carry on: 1225 / 921

On to step 4:
921 can be fit into 1225 1 times, resulting in a remainder of 304.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 921 from 1225 leaves us with 304.
Include the next digit (6) from the dividend after 304, then repeat: 3046 / 921

Going ahead to step 5:
921 can be fit into 3046 3 times, resulting in a remainder of 283.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 2763 from 3046 leaves us with 283.
Grab the next digit (5) from the dividend, add it to 283, then carry on: 2835 / 921

Let's proceed to step 6:
When dividing 2835 by 921, we get 3 with a remainder of 72.
The next digit of our result is 3. 
Result so far: 133.0
Subtracting 2763 from 2835 leaves us with 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 921

On to step 7:
When dividing 723 by 921, we get 0 with a remainder of 723.
Put 0 as the next digit of the answer. 
Result so far: 1330.0
If we subtract 0 from 723, we get 723.
Include the next digit (4) from the dividend after 723, then repeat: 7234 / 921

On to step 8:
If we divide 7234 by 921, we get 7 and a remainder of 787.
Put 7 as the next digit of the answer. 
Result so far: 13307.0
Subtract 6447 from 7234 to get 787.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7870, and continue the process.

On to step 9:
921 goes into 7870 8 times with a remainder of 502.
The next digit of our result is 8. 
Result so far: 13307.8
The remainder is 502 after subtracting 7368 from 7870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Moving on to step 10:
When dividing 5020 by 921, we get 5 with a remainder of 415.
The next digit of our result is 5. 
Result so far: 13307.85
Subtracting 4605 from 5020 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

On to step 11:
The number 921 fits into 4150 4 times, leaving a remainder of 466.
Write down 4 as next digit of the result. 
Result so far: 13307.854
If we take 3684 away from 4150, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 12:
The number 921 fits into 4660 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 13307.8545
If we subtract 4605 from 4660, we get 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 13:
921 goes into 550 0 times with a remainder of 550.
Put 0 as the next digit of the answer. 
Result so far: 13307.8545
Subtract 0 from 550 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 14:
921 goes into 5500 5 times with a remainder of 895.
Write down 5 as next digit of the result. 
Result so far: 13307.854505
The remainder is 895 after subtracting 4605 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8950, and continue the process.

On to step 15:
921 can be fit into 8950 9 times, resulting in a remainder of 661.
Write down 9 as next digit of the result. 
Result so far: 13307.8545059
The remainder is 661 after subtracting 8289 from 8950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

Going ahead to step 16:
When dividing 6610 by 921, we get 7 with a remainder of 163.
The number 7 becomes the next digit in our result. 
Result so far: 13307.85450597
Subtracting 6447 from 6610 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

After the division, we end up with 13307.85450597 and a remainder of 1.63e-07.
