We're dividing 9749754 by 999 
The aim is to understand the frequency of 999 in 9749754.

Let's proceed to step 1:
999 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 999

Going ahead to step 2:
When dividing 97 by 999, we get 0 with a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Append the next digit (4) from the dividend to 97 and continue with: 974 / 999

Going ahead to step 3:
The number 999 fits into 974 0 times, leaving a remainder of 974.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 974 and we're left with 974.
Fetch the next digit (9) from the dividend, attach it to 974 and continue: 9749 / 999

Advancing to step 4:
999 can be fit into 9749 9 times, resulting in a remainder of 758.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 8991 from 9749 leaves us with 758.
Append the next digit (7) from the dividend to 758 and continue with: 7587 / 999

Going ahead to step 5:
7587 divided by 999 is 7 with a remainder of 594.
The next digit of our result is 7. 
Result so far: 97.0
Subtract 6993 from 7587 to get 594.
Append the next digit (5) from the dividend to 594 and continue with: 5945 / 999

Going ahead to step 6:
5945 divided by 999 is 5 with a remainder of 950.
The next digit of our result is 5. 
Result so far: 975.0
Subtracting 4995 from 5945 leaves us with 950.
Take the next digit (4) from the dividend and append it to 950, then repeat: 9504 / 999

Advancing to step 7:
If we divide 9504 by 999, we get 9 and a remainder of 513.
Record the quotient 9 as the next digit in the result. 
Result so far: 9759.0
If we subtract 8991 from 9504, we get 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Advancing to step 8:
999 can be fit into 5130 5 times, resulting in a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 9759.5
The remainder is 135 after subtracting 4995 from 5130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 9:
When dividing 1350 by 999, we get 1 with a remainder of 351.
Use 1 as the next digit of our solution. 
Result so far: 9759.51
Subtracting 999 from 1350 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 10:
3510 divided by 999 is 3 with a remainder of 513.
The number 3 becomes the next digit in our result. 
Result so far: 9759.513
Subtract 2997 from 3510 to get 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Let's proceed to step 11:
If we divide 5130 by 999, we get 5 and a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 9759.5135
If we subtract 4995 from 5130, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 12:
The number 999 fits into 1350 1 times, leaving a remainder of 351.
Use 1 as the next digit of our solution. 
Result so far: 9759.51351
Deduct 999 from 1350 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 13:
When dividing 3510 by 999, we get 3 with a remainder of 513.
Write down 3 as next digit of the result. 
Result so far: 9759.513513
Subtract 2997 from 3510 to get 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Let's proceed to step 14:
5130 divided by 999 is 5 with a remainder of 135.
The next digit of our result is 5. 
Result so far: 9759.5135135
The remainder is 135 after subtracting 4995 from 5130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 15:
When dividing 1350 by 999, we get 1 with a remainder of 351.
Use 1 as the next digit of our solution. 
Result so far: 9759.51351351
Deduct 999 from 1350 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

The final result is 9759.51351351 with a remainder of 3.51e-07.
