We divide 88371689 by 399
We're looking to find how many times 399 goes into 88371689.

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
Subtract 0 from 8 to get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 399

Moving on to step 2:
The number 399 fits into 88 0 times, leaving a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Fetch the next digit (3) from the dividend, attach it to 88 and continue: 883 / 399

Advancing to step 3:
883 divided by 399 is 2 with a remainder of 85.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 85 after subtracting 798 from 883.
Bring next digit (7) of the dividend behind the 85 and repeat the process: 857 / 399

Step 4:
The number 399 fits into 857 2 times, leaving a remainder of 59.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 798 from 857, we get 59.
Fetch the next digit (1) from the dividend, attach it to 59 and continue: 591 / 399

On to step 5:
399 goes into 591 1 times with a remainder of 192.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.0
If we take 399 away from 591, we end up with 192.
Grab the next digit (6) from the dividend, add it to 192, then carry on: 1926 / 399

Step 6:
399 goes into 1926 4 times with a remainder of 330.
Record the quotient 4 as the next digit in the result. 
Result so far: 2214.0
Deduct 1596 from 1926 and we're left with 330.
Include the next digit (8) from the dividend after 330, then repeat: 3308 / 399

On to step 7:
The number 399 fits into 3308 8 times, leaving a remainder of 116.
The number 8 becomes the next digit in our result. 
Result so far: 22148.0
Subtracting 3192 from 3308 leaves us with 116.
Bring next digit (9) of the dividend behind the 116 and repeat the process: 1169 / 399

Going ahead to step 8:
The number 399 fits into 1169 2 times, leaving a remainder of 371.
The number 2 becomes the next digit in our result. 
Result so far: 221482.0
If we subtract 798 from 1169, we get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Moving on to step 9:
399 can be fit into 3710 9 times, resulting in a remainder of 119.
The number 9 becomes the next digit in our result. 
Result so far: 221482.9
Subtracting 3591 from 3710 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 10:
1190 divided by 399 is 2 with a remainder of 392.
The next digit of our result is 2. 
Result so far: 221482.92
If we subtract 798 from 1190, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 11:
When dividing 3920 by 399, we get 9 with a remainder of 329.
The next digit of our result is 9. 
Result so far: 221482.929
If we subtract 3591 from 3920, we get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Step 12:
3290 divided by 399 is 8 with a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 221482.9298
Subtracting 3192 from 3290 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 13:
When dividing 980 by 399, we get 2 with a remainder of 182.
The number 2 becomes the next digit in our result. 
Result so far: 221482.92982
The remainder is 182 after subtracting 798 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 14:
The number 399 fits into 1820 4 times, leaving a remainder of 224.
Use 4 as the next digit of our solution. 
Result so far: 221482.929824
If we subtract 1596 from 1820, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 15:
The number 399 fits into 2240 5 times, leaving a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 221482.9298245
If we take 1995 away from 2240, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 16:
The number 399 fits into 2450 6 times, leaving a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 221482.92982456
Subtract 2394 from 2450 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 221482.92982456 with a remaining 5.6e-08.
