77191353 divided by 923 
The aim is to understand the frequency of 923 in 77191353.

Let's proceed to step 1:
If we divide 7 by 923, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 923

Moving on to step 2:
If we divide 77 by 923, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 923

On to step 3:
923 goes into 771 0 times with a remainder of 771.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 771, we get 771.
Grab the next digit (9) from the dividend, add it to 771, then carry on: 7719 / 923

Advancing to step 4:
The number 923 fits into 7719 8 times, leaving a remainder of 335.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 7384 from 7719 to get 335.
Fetch the next digit (1) from the dividend, attach it to 335 and continue: 3351 / 923

Advancing to step 5:
The number 923 fits into 3351 3 times, leaving a remainder of 582.
Put 3 as the next digit of the answer. 
Result so far: 83.0
The remainder is 582 after subtracting 2769 from 3351.
Take the next digit (3) from the dividend and append it to 582, then repeat: 5823 / 923

Moving on to step 6:
923 goes into 5823 6 times with a remainder of 285.
Use 6 as the next digit of our solution. 
Result so far: 836.0
If we subtract 5538 from 5823, we get 285.
Take the next digit (5) from the dividend and append it to 285, then repeat: 2855 / 923

Going ahead to step 7:
The number 923 fits into 2855 3 times, leaving a remainder of 86.
Write down 3 as next digit of the result. 
Result so far: 8363.0
Subtracting 2769 from 2855 leaves us with 86.
Fetch the next digit (3) from the dividend, attach it to 86 and continue: 863 / 923

Step 8:
The number 923 fits into 863 0 times, leaving a remainder of 863.
The next digit of our result is 0. 
Result so far: 83630.0
Subtract 0 from 863 to get 863.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8630, and continue the process.

Moving on to step 9:
If we divide 8630 by 923, we get 9 and a remainder of 323.
Use 9 as the next digit of our solution. 
Result so far: 83630.9
Subtracting 8307 from 8630 leaves us with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Let's proceed to step 10:
If we divide 3230 by 923, we get 3 and a remainder of 461.
The number 3 becomes the next digit in our result. 
Result so far: 83630.93
If we subtract 2769 from 3230, we get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Advancing to step 11:
When dividing 4610 by 923, we get 4 with a remainder of 918.
Write down 4 as next digit of the result. 
Result so far: 83630.934
Deduct 3692 from 4610 and we're left with 918.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9180, and continue the process.

Moving on to step 12:
The number 923 fits into 9180 9 times, leaving a remainder of 873.
Write down 9 as next digit of the result. 
Result so far: 83630.9349
Deduct 8307 from 9180 and we're left with 873.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8730, and continue the process.

Advancing to step 13:
8730 divided by 923 is 9 with a remainder of 423.
Record the quotient 9 as the next digit in the result. 
Result so far: 83630.93499
The remainder is 423 after subtracting 8307 from 8730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Our division results in 83630.93499 with a remaining 0.000423.
