We're dividing 7303233 by 999 
The aim is to understand the frequency of 999 in 7303233.

Advancing to step 1:
When dividing 7 by 999, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 999

Going ahead to step 2:
73 divided by 999 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Fetch the next digit (0) from the dividend, attach it to 73 and continue: 730 / 999

Going ahead to step 3:
The number 999 fits into 730 0 times, leaving a remainder of 730.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 730 leaves us with 730.
Include the next digit (3) from the dividend after 730, then repeat: 7303 / 999

Moving on to step 4:
If we divide 7303 by 999, we get 7 and a remainder of 310.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 310 after subtracting 6993 from 7303.
Append the next digit (2) from the dividend to 310 and continue with: 3102 / 999

Advancing to step 5:
999 can be fit into 3102 3 times, resulting in a remainder of 105.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
If we subtract 2997 from 3102, we get 105.
Grab the next digit (3) from the dividend, add it to 105, then carry on: 1053 / 999

Let's proceed to step 6:
999 can be fit into 1053 1 times, resulting in a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 731.0
If we take 999 away from 1053, we end up with 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 999

Advancing to step 7:
999 can be fit into 543 0 times, resulting in a remainder of 543.
Use 0 as the next digit of our solution. 
Result so far: 7310.0
Deduct 0 from 543 and we're left with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Advancing to step 8:
If we divide 5430 by 999, we get 5 and a remainder of 435.
Use 5 as the next digit of our solution. 
Result so far: 7310.5
If we subtract 4995 from 5430, we get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Moving on to step 9:
999 can be fit into 4350 4 times, resulting in a remainder of 354.
Record the quotient 4 as the next digit in the result. 
Result so far: 7310.54
Subtracting 3996 from 4350 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 10:
When dividing 3540 by 999, we get 3 with a remainder of 543.
The next digit of our result is 3. 
Result so far: 7310.543
The remainder is 543 after subtracting 2997 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Going ahead to step 11:
If we divide 5430 by 999, we get 5 and a remainder of 435.
Record the quotient 5 as the next digit in the result. 
Result so far: 7310.5435
Subtract 4995 from 5430 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Moving on to step 12:
999 can be fit into 4350 4 times, resulting in a remainder of 354.
Write down 4 as next digit of the result. 
Result so far: 7310.54354
If we subtract 3996 from 4350, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 13:
999 goes into 3540 3 times with a remainder of 543.
Put 3 as the next digit of the answer. 
Result so far: 7310.543543
Subtracting 2997 from 3540 leaves us with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Step 14:
The number 999 fits into 5430 5 times, leaving a remainder of 435.
Write down 5 as next digit of the result. 
Result so far: 7310.5435435
Deduct 4995 from 5430 and we're left with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Step 15:
If we divide 4350 by 999, we get 4 and a remainder of 354.
The next digit of our result is 4. 
Result so far: 7310.54354354
If we subtract 3996 from 4350, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

The quotient of the division is 7310.54354354, and the remainder is 3.54e-07.
