Let's divide 68399170 by 399
We're looking to find how many times 399 goes into 68399170.

Moving on to step 1:
The number 399 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 399

Going ahead to step 2:
The number 399 fits into 68 0 times, leaving a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 399

Let's proceed to step 3:
399 can be fit into 683 1 times, resulting in a remainder of 284.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 399 away from 683, we end up with 284.
Grab the next digit (9) from the dividend, add it to 284, then carry on: 2849 / 399

On to step 4:
If we divide 2849 by 399, we get 7 and a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 2793 from 2849 and we're left with 56.
Append the next digit (9) from the dividend to 56 and continue with: 569 / 399

Let's proceed to step 5:
When dividing 569 by 399, we get 1 with a remainder of 170.
Write down 1 as next digit of the result. 
Result so far: 171.0
If we take 399 away from 569, we end up with 170.
Grab the next digit (1) from the dividend, add it to 170, then carry on: 1701 / 399

On to step 6:
The number 399 fits into 1701 4 times, leaving a remainder of 105.
Put 4 as the next digit of the answer. 
Result so far: 1714.0
If we subtract 1596 from 1701, we get 105.
Fetch the next digit (7) from the dividend, attach it to 105 and continue: 1057 / 399

Step 7:
When dividing 1057 by 399, we get 2 with a remainder of 259.
Record the quotient 2 as the next digit in the result. 
Result so far: 17142.0
Subtract 798 from 1057 to get 259.
Grab the next digit (0) from the dividend, add it to 259, then carry on: 2590 / 399

On to step 8:
2590 divided by 399 is 6 with a remainder of 196.
The number 6 becomes the next digit in our result. 
Result so far: 171426.0
Subtracting 2394 from 2590 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 9:
If we divide 1960 by 399, we get 4 and a remainder of 364.
The number 4 becomes the next digit in our result. 
Result so far: 171426.4
Subtract 1596 from 1960 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 10:
The number 399 fits into 3640 9 times, leaving a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 171426.49
Deduct 3591 from 3640 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 11:
If we divide 490 by 399, we get 1 and a remainder of 91.
The next digit of our result is 1. 
Result so far: 171426.491
If we take 399 away from 490, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 12:
If we divide 910 by 399, we get 2 and a remainder of 112.
The number 2 becomes the next digit in our result. 
Result so far: 171426.4912
If we take 798 away from 910, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 13:
The number 399 fits into 1120 2 times, leaving a remainder of 322.
Record the quotient 2 as the next digit in the result. 
Result so far: 171426.49122
If we take 798 away from 1120, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

The final outcome is 171426.49122, with a leftover of 0.000322.
