Let's divide 71225702 by 999
The aim is to understand the frequency of 999 in 71225702.

Advancing to step 1:
999 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 999

Going ahead to step 2:
When dividing 71 by 999, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Grab the next digit (2) from the dividend, add it to 71, then carry on: 712 / 999

Advancing to step 3:
999 goes into 712 0 times with a remainder of 712.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 712 and we're left with 712.
Bring next digit (2) of the dividend behind the 712 and repeat the process: 7122 / 999

On to step 4:
The number 999 fits into 7122 7 times, leaving a remainder of 129.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 6993 from 7122 and we're left with 129.
Append the next digit (5) from the dividend to 129 and continue with: 1295 / 999

Moving on to step 5:
1295 divided by 999 is 1 with a remainder of 296.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we take 999 away from 1295, we end up with 296.
Include the next digit (7) from the dividend after 296, then repeat: 2967 / 999

Going ahead to step 6:
If we divide 2967 by 999, we get 2 and a remainder of 969.
Write down 2 as next digit of the result. 
Result so far: 712.0
If we subtract 1998 from 2967, we get 969.
Grab the next digit (0) from the dividend, add it to 969, then carry on: 9690 / 999

Let's proceed to step 7:
When dividing 9690 by 999, we get 9 with a remainder of 699.
The number 9 becomes the next digit in our result. 
Result so far: 7129.0
Subtracting 8991 from 9690 leaves us with 699.
Take the next digit (2) from the dividend and append it to 699, then repeat: 6992 / 999

Moving on to step 8:
6992 divided by 999 is 6 with a remainder of 998.
The next digit of our result is 6. 
Result so far: 71296.0
If we subtract 5994 from 6992, we get 998.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9980, and continue the process.

On to step 9:
999 can be fit into 9980 9 times, resulting in a remainder of 989.
Write down 9 as next digit of the result. 
Result so far: 71296.9
Subtracting 8991 from 9980 leaves us with 989.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9890, and continue the process.

On to step 10:
If we divide 9890 by 999, we get 9 and a remainder of 899.
Use 9 as the next digit of our solution. 
Result so far: 71296.99
Subtract 8991 from 9890 to get 899.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8990, and continue the process.

The final outcome is 71296.99, with a leftover of 0.899.
