Let's divide 86329168 by 399
We want to figure out the number of times 86329168 can be divided by 399.

Going ahead to step 1:
399 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 399

On to step 2:
If we divide 86 by 399, we get 0 and a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Include the next digit (3) from the dividend after 86, then repeat: 863 / 399

Let's proceed to step 3:
399 goes into 863 2 times with a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 798 from 863 and we're left with 65.
Take the next digit (2) from the dividend and append it to 65, then repeat: 652 / 399

Advancing to step 4:
399 can be fit into 652 1 times, resulting in a remainder of 253.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 399 from 652 to get 253.
Grab the next digit (9) from the dividend, add it to 253, then carry on: 2539 / 399

Let's proceed to step 5:
399 can be fit into 2539 6 times, resulting in a remainder of 145.
The number 6 becomes the next digit in our result. 
Result so far: 216.0
The remainder is 145 after subtracting 2394 from 2539.
Include the next digit (1) from the dividend after 145, then repeat: 1451 / 399

Step 6:
When dividing 1451 by 399, we get 3 with a remainder of 254.
The next digit of our result is 3. 
Result so far: 2163.0
If we take 1197 away from 1451, we end up with 254.
Take the next digit (6) from the dividend and append it to 254, then repeat: 2546 / 399

On to step 7:
399 goes into 2546 6 times with a remainder of 152.
The next digit of our result is 6. 
Result so far: 21636.0
If we subtract 2394 from 2546, we get 152.
Append the next digit (8) from the dividend to 152 and continue with: 1528 / 399

Going ahead to step 8:
399 can be fit into 1528 3 times, resulting in a remainder of 331.
The next digit of our result is 3. 
Result so far: 216363.0
Subtracting 1197 from 1528 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Let's proceed to step 9:
The number 399 fits into 3310 8 times, leaving a remainder of 118.
Record the quotient 8 as the next digit in the result. 
Result so far: 216363.8
Deduct 3192 from 3310 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 10:
When dividing 1180 by 399, we get 2 with a remainder of 382.
The next digit of our result is 2. 
Result so far: 216363.82
Subtract 798 from 1180 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Let's proceed to step 11:
399 goes into 3820 9 times with a remainder of 229.
The number 9 becomes the next digit in our result. 
Result so far: 216363.829
If we subtract 3591 from 3820, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Moving on to step 12:
When dividing 2290 by 399, we get 5 with a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 216363.8295
If we subtract 1995 from 2290, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 13:
399 can be fit into 2950 7 times, resulting in a remainder of 157.
Record the quotient 7 as the next digit in the result. 
Result so far: 216363.82957
If we take 2793 away from 2950, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 14:
1570 divided by 399 is 3 with a remainder of 373.
Write down 3 as next digit of the result. 
Result so far: 216363.829573
The remainder is 373 after subtracting 1197 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

On to step 15:
399 goes into 3730 9 times with a remainder of 139.
Put 9 as the next digit of the answer. 
Result so far: 216363.8295739
If we take 3591 away from 3730, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 16:
If we divide 1390 by 399, we get 3 and a remainder of 193.
Use 3 as the next digit of our solution. 
Result so far: 216363.82957393
The remainder is 193 after subtracting 1197 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

In conclusion, the division gives 216363.82957393 with a balance of 1.93e-07.
