Let's divide 12010085 by 999
The aim is to understand the frequency of 999 in 12010085.

On to step 1:
If we divide 1 by 999, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 999

Let's proceed to step 2:
12 divided by 999 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 999

Let's proceed to step 3:
999 can be fit into 120 0 times, resulting in a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 120, we get 120.
Fetch the next digit (1) from the dividend, attach it to 120 and continue: 1201 / 999

On to step 4:
The number 999 fits into 1201 1 times, leaving a remainder of 202.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 999 from 1201 and we're left with 202.
Bring next digit (0) of the dividend behind the 202 and repeat the process: 2020 / 999

Let's proceed to step 5:
999 goes into 2020 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 22 after subtracting 1998 from 2020.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 999

Advancing to step 6:
999 goes into 220 0 times with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
Subtracting 0 from 220 leaves us with 220.
Append the next digit (8) from the dividend to 220 and continue with: 2208 / 999

Advancing to step 7:
The number 999 fits into 2208 2 times, leaving a remainder of 210.
Use 2 as the next digit of our solution. 
Result so far: 1202.0
Deduct 1998 from 2208 and we're left with 210.
Take the next digit (5) from the dividend and append it to 210, then repeat: 2105 / 999

Going ahead to step 8:
If we divide 2105 by 999, we get 2 and a remainder of 107.
Record the quotient 2 as the next digit in the result. 
Result so far: 12022.0
The remainder is 107 after subtracting 1998 from 2105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 9:
999 can be fit into 1070 1 times, resulting in a remainder of 71.
The next digit of our result is 1. 
Result so far: 12022.1
Deduct 999 from 1070 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 10:
The number 999 fits into 710 0 times, leaving a remainder of 710.
Put 0 as the next digit of the answer. 
Result so far: 12022.1
Subtract 0 from 710 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Moving on to step 11:
7100 divided by 999 is 7 with a remainder of 107.
Record the quotient 7 as the next digit in the result. 
Result so far: 12022.107
Subtract 6993 from 7100 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 12:
999 can be fit into 1070 1 times, resulting in a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 12022.1071
Subtracting 999 from 1070 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 13:
If we divide 710 by 999, we get 0 and a remainder of 710.
The number 0 becomes the next digit in our result. 
Result so far: 12022.1071
Subtract 0 from 710 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Let's proceed to step 14:
7100 divided by 999 is 7 with a remainder of 107.
Put 7 as the next digit of the answer. 
Result so far: 12022.107107
Subtract 6993 from 7100 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 15:
999 can be fit into 1070 1 times, resulting in a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 12022.1071071
If we subtract 999 from 1070, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 16:
If we divide 710 by 999, we get 0 and a remainder of 710.
The next digit of our result is 0. 
Result so far: 12022.1071071
Deduct 0 from 710 and we're left with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

In conclusion, the division gives 12022.1071071 with a balance of 7.1e-07.
