91007995 divided by 124 
The aim is to understand the frequency of 124 in 91007995.

On to step 1:
When dividing 9 by 124, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 124

Let's proceed to step 2:
If we divide 91 by 124, we get 0 and a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (0) from the dividend and append it to 91, then repeat: 910 / 124

On to step 3:
124 can be fit into 910 7 times, resulting in a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 868 from 910 leaves us with 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 124

Going ahead to step 4:
When dividing 420 by 124, we get 3 with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Subtracting 372 from 420 leaves us with 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 124

On to step 5:
If we divide 487 by 124, we get 3 and a remainder of 115.
Put 3 as the next digit of the answer. 
Result so far: 733.0
Subtract 372 from 487 to get 115.
Append the next digit (9) from the dividend to 115 and continue with: 1159 / 124

Advancing to step 6:
124 goes into 1159 9 times with a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 7339.0
Deduct 1116 from 1159 and we're left with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 124

Step 7:
When dividing 439 by 124, we get 3 with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 73393.0
Subtracting 372 from 439 leaves us with 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 124

Advancing to step 8:
If we divide 675 by 124, we get 5 and a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 733935.0
Subtracting 620 from 675 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
550 divided by 124 is 4 with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 733935.4
Subtract 496 from 550 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
When dividing 540 by 124, we get 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 733935.44
Subtract 496 from 540 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 733935.44 with a balance of 0.044.
