71459786 divided by 999 
The aim is to understand the frequency of 999 in 71459786.

Moving on 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
Subtracting 0 from 7 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 999

Step 2:
999 goes into 71 0 times with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 999

Moving on to step 3:
When dividing 714 by 999, we get 0 with a remainder of 714.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 714, we get 714.
Include the next digit (5) from the dividend after 714, then repeat: 7145 / 999

Let's proceed to step 4:
999 can be fit into 7145 7 times, resulting in a remainder of 152.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 6993 from 7145 to get 152.
Fetch the next digit (9) from the dividend, attach it to 152 and continue: 1529 / 999

Step 5:
When dividing 1529 by 999, we get 1 with a remainder of 530.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Subtracting 999 from 1529 leaves us with 530.
Include the next digit (7) from the dividend after 530, then repeat: 5307 / 999

Let's proceed to step 6:
999 can be fit into 5307 5 times, resulting in a remainder of 312.
Write down 5 as next digit of the result. 
Result so far: 715.0
If we take 4995 away from 5307, we end up with 312.
Include the next digit (8) from the dividend after 312, then repeat: 3128 / 999

Let's proceed to step 7:
When dividing 3128 by 999, we get 3 with a remainder of 131.
Record the quotient 3 as the next digit in the result. 
Result so far: 7153.0
The remainder is 131 after subtracting 2997 from 3128.
Include the next digit (6) from the dividend after 131, then repeat: 1316 / 999

Going ahead to step 8:
1316 divided by 999 is 1 with a remainder of 317.
Write down 1 as next digit of the result. 
Result so far: 71531.0
Subtract 999 from 1316 to get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Moving on to step 9:
When dividing 3170 by 999, we get 3 with a remainder of 173.
The next digit of our result is 3. 
Result so far: 71531.3
Subtracting 2997 from 3170 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

On to step 10:
999 goes into 1730 1 times with a remainder of 731.
The number 1 becomes the next digit in our result. 
Result so far: 71531.31
If we subtract 999 from 1730, we get 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Let's proceed to step 11:
999 goes into 7310 7 times with a remainder of 317.
Put 7 as the next digit of the answer. 
Result so far: 71531.317
Subtracting 6993 from 7310 leaves us with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Let's proceed to step 12:
999 goes into 3170 3 times with a remainder of 173.
Record the quotient 3 as the next digit in the result. 
Result so far: 71531.3173
Subtracting 2997 from 3170 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

On to step 13:
1730 divided by 999 is 1 with a remainder of 731.
Put 1 as the next digit of the answer. 
Result so far: 71531.31731
If we take 999 away from 1730, we end up with 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Moving on to step 14:
999 can be fit into 7310 7 times, resulting in a remainder of 317.
Put 7 as the next digit of the answer. 
Result so far: 71531.317317
Subtracting 6993 from 7310 leaves us with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Advancing to step 15:
3170 divided by 999 is 3 with a remainder of 173.
The number 3 becomes the next digit in our result. 
Result so far: 71531.3173173
If we subtract 2997 from 3170, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Step 16:
The number 999 fits into 1730 1 times, leaving a remainder of 731.
Record the quotient 1 as the next digit in the result. 
Result so far: 71531.31731731
Deduct 999 from 1730 and we're left with 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

The final outcome is 71531.31731731, with a leftover of 7.31e-07.
