81255872 ÷ 924 
The aim is to understand the frequency of 924 in 81255872.

Going ahead to step 1:
8 divided by 924 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 924

Let's proceed to step 2:
924 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 924

Let's proceed to step 3:
924 goes into 812 0 times with a remainder of 812.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 812 leaves us with 812.
Grab the next digit (5) from the dividend, add it to 812, then carry on: 8125 / 924

Advancing to step 4:
8125 divided by 924 is 8 with a remainder of 733.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 7392 from 8125, we get 733.
Grab the next digit (5) from the dividend, add it to 733, then carry on: 7335 / 924

Going ahead to step 5:
The number 924 fits into 7335 7 times, leaving a remainder of 867.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we take 6468 away from 7335, we end up with 867.
Fetch the next digit (8) from the dividend, attach it to 867 and continue: 8678 / 924

Let's proceed to step 6:
924 goes into 8678 9 times with a remainder of 362.
The next digit of our result is 9. 
Result so far: 879.0
Deduct 8316 from 8678 and we're left with 362.
Bring next digit (7) of the dividend behind the 362 and repeat the process: 3627 / 924

Going ahead to step 7:
3627 divided by 924 is 3 with a remainder of 855.
Put 3 as the next digit of the answer. 
Result so far: 8793.0
If we take 2772 away from 3627, we end up with 855.
Grab the next digit (2) from the dividend, add it to 855, then carry on: 8552 / 924

Moving on to step 8:
If we divide 8552 by 924, we get 9 and a remainder of 236.
Put 9 as the next digit of the answer. 
Result so far: 87939.0
Deduct 8316 from 8552 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 9:
924 can be fit into 2360 2 times, resulting in a remainder of 512.
Use 2 as the next digit of our solution. 
Result so far: 87939.2
Deduct 1848 from 2360 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 10:
When dividing 5120 by 924, we get 5 with a remainder of 500.
The next digit of our result is 5. 
Result so far: 87939.25
Deduct 4620 from 5120 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 11:
The number 924 fits into 5000 5 times, leaving a remainder of 380.
The next digit of our result is 5. 
Result so far: 87939.255
Subtract 4620 from 5000 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Our division results in 87939.255 with a remaining 0.038.
