88723986 divided by 399 
Our goal is to divide 88723986 by 399.

Let's proceed to step 1:
The number 399 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 399

Let's proceed to step 2:
88 divided by 399 is 0 with a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Grab the next digit (7) from the dividend, add it to 88, then carry on: 887 / 399

Step 3:
399 goes into 887 2 times with a remainder of 89.
The next digit of our result is 2. 
Result so far: 2.0
If we take 798 away from 887, we end up with 89.
Fetch the next digit (2) from the dividend, attach it to 89 and continue: 892 / 399

On to step 4:
When dividing 892 by 399, we get 2 with a remainder of 94.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 94 after subtracting 798 from 892.
Bring next digit (3) of the dividend behind the 94 and repeat the process: 943 / 399

Moving on to step 5:
943 divided by 399 is 2 with a remainder of 145.
Record the quotient 2 as the next digit in the result. 
Result so far: 222.0
Subtract 798 from 943 to get 145.
Append the next digit (9) from the dividend to 145 and continue with: 1459 / 399

Advancing to step 6:
399 goes into 1459 3 times with a remainder of 262.
Put 3 as the next digit of the answer. 
Result so far: 2223.0
If we take 1197 away from 1459, we end up with 262.
Bring next digit (8) of the dividend behind the 262 and repeat the process: 2628 / 399

On to step 7:
399 goes into 2628 6 times with a remainder of 234.
The number 6 becomes the next digit in our result. 
Result so far: 22236.0
If we subtract 2394 from 2628, we get 234.
Bring next digit (6) of the dividend behind the 234 and repeat the process: 2346 / 399

Step 8:
The number 399 fits into 2346 5 times, leaving a remainder of 351.
Record the quotient 5 as the next digit in the result. 
Result so far: 222365.0
Deduct 1995 from 2346 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 9:
399 can be fit into 3510 8 times, resulting in a remainder of 318.
Write down 8 as next digit of the result. 
Result so far: 222365.8
Subtracting 3192 from 3510 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 10:
If we divide 3180 by 399, we get 7 and a remainder of 387.
Write down 7 as next digit of the result. 
Result so far: 222365.87
If we subtract 2793 from 3180, we get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Step 11:
If we divide 3870 by 399, we get 9 and a remainder of 279.
Record the quotient 9 as the next digit in the result. 
Result so far: 222365.879
The remainder is 279 after subtracting 3591 from 3870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 12:
If we divide 2790 by 399, we get 6 and a remainder of 396.
Write down 6 as next digit of the result. 
Result so far: 222365.8796
Subtracting 2394 from 2790 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 13:
3960 divided by 399 is 9 with a remainder of 369.
Put 9 as the next digit of the answer. 
Result so far: 222365.87969
The remainder is 369 after subtracting 3591 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Going ahead to step 14:
When dividing 3690 by 399, we get 9 with a remainder of 99.
Put 9 as the next digit of the answer. 
Result so far: 222365.879699
If we take 3591 away from 3690, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

After the division, we end up with 222365.879699 and a remainder of 9.9e-06.
