Let's divide 86265914 by 999
Our goal is to divide 86265914 by 999.

Advancing to step 1:
The number 999 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 999

Let's proceed to step 2:
If we divide 86 by 999, we get 0 and a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Include the next digit (2) from the dividend after 86, then repeat: 862 / 999

Advancing to step 3:
The number 999 fits into 862 0 times, leaving a remainder of 862.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 862 leaves us with 862.
Fetch the next digit (6) from the dividend, attach it to 862 and continue: 8626 / 999

Advancing to step 4:
The number 999 fits into 8626 8 times, leaving a remainder of 634.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 7992 away from 8626, we end up with 634.
Bring next digit (5) of the dividend behind the 634 and repeat the process: 6345 / 999

Let's proceed to step 5:
6345 divided by 999 is 6 with a remainder of 351.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we take 5994 away from 6345, we end up with 351.
Take the next digit (9) from the dividend and append it to 351, then repeat: 3519 / 999

Going ahead to step 6:
If we divide 3519 by 999, we get 3 and a remainder of 522.
The next digit of our result is 3. 
Result so far: 863.0
Subtracting 2997 from 3519 leaves us with 522.
Grab the next digit (1) from the dividend, add it to 522, then carry on: 5221 / 999

On to step 7:
5221 divided by 999 is 5 with a remainder of 226.
The next digit of our result is 5. 
Result so far: 8635.0
If we take 4995 away from 5221, we end up with 226.
Append the next digit (4) from the dividend to 226 and continue with: 2264 / 999

Going ahead to step 8:
The number 999 fits into 2264 2 times, leaving a remainder of 266.
The next digit of our result is 2. 
Result so far: 86352.0
If we subtract 1998 from 2264, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 9:
999 can be fit into 2660 2 times, resulting in a remainder of 662.
Put 2 as the next digit of the answer. 
Result so far: 86352.2
The remainder is 662 after subtracting 1998 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

On to step 10:
The number 999 fits into 6620 6 times, leaving a remainder of 626.
Write down 6 as next digit of the result. 
Result so far: 86352.26
The remainder is 626 after subtracting 5994 from 6620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Let's proceed to step 11:
If we divide 6260 by 999, we get 6 and a remainder of 266.
Use 6 as the next digit of our solution. 
Result so far: 86352.266
If we subtract 5994 from 6260, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

The final result is 86352.266 with a remainder of 0.0266.
