We're dividing 56882165 by 399 
We want to divide 56882165 by 399.

Advancing to step 1:
The number 399 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 399

On to step 2:
56 divided by 399 is 0 with a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Append the next digit (8) from the dividend to 56 and continue with: 568 / 399

Going ahead to step 3:
If we divide 568 by 399, we get 1 and a remainder of 169.
The next digit of our result is 1. 
Result so far: 1.0
If we take 399 away from 568, we end up with 169.
Take the next digit (8) from the dividend and append it to 169, then repeat: 1698 / 399

Advancing to step 4:
1698 divided by 399 is 4 with a remainder of 102.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 1596 from 1698 and we're left with 102.
Include the next digit (2) from the dividend after 102, then repeat: 1022 / 399

On to step 5:
399 goes into 1022 2 times with a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
If we take 798 away from 1022, we end up with 224.
Append the next digit (1) from the dividend to 224 and continue with: 2241 / 399

On to step 6:
When dividing 2241 by 399, we get 5 with a remainder of 246.
Use 5 as the next digit of our solution. 
Result so far: 1425.0
If we subtract 1995 from 2241, we get 246.
Include the next digit (6) from the dividend after 246, then repeat: 2466 / 399

Going ahead to step 7:
When dividing 2466 by 399, we get 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 14256.0
If we take 2394 away from 2466, we end up with 72.
Grab the next digit (5) from the dividend, add it to 72, then carry on: 725 / 399

Advancing to step 8:
399 can be fit into 725 1 times, resulting in a remainder of 326.
Record the quotient 1 as the next digit in the result. 
Result so far: 142561.0
If we take 399 away from 725, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Step 9:
The number 399 fits into 3260 8 times, leaving a remainder of 68.
The next digit of our result is 8. 
Result so far: 142561.8
Subtracting 3192 from 3260 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
If we divide 680 by 399, we get 1 and a remainder of 281.
Write down 1 as next digit of the result. 
Result so far: 142561.81
If we take 399 away from 680, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Let's proceed to step 11:
399 goes into 2810 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 142561.817
If we take 2793 away from 2810, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 12:
When dividing 170 by 399, we get 0 with a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 142561.817
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 13:
399 goes into 1700 4 times with a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 142561.81704
Deduct 1596 from 1700 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 14:
399 can be fit into 1040 2 times, resulting in a remainder of 242.
Record the quotient 2 as the next digit in the result. 
Result so far: 142561.817042
Subtract 798 from 1040 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 15:
2420 divided by 399 is 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 142561.8170426
Subtract 2394 from 2420 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 16:
If we divide 260 by 399, we get 0 and a remainder of 260.
The next digit of our result is 0. 
Result so far: 142561.8170426
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 142561.8170426, with a leftover of 2.6e-07.
