Let's divide 67287419 by 399
We're looking to find how many times 399 goes into 67287419.

Going ahead to step 1:
399 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 399

Going ahead to step 2:
When dividing 67 by 399, we get 0 with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Take the next digit (2) from the dividend and append it to 67, then repeat: 672 / 399

Advancing to step 3:
If we divide 672 by 399, we get 1 and a remainder of 273.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 399 from 672, we get 273.
Take the next digit (8) from the dividend and append it to 273, then repeat: 2738 / 399

On to step 4:
399 goes into 2738 6 times with a remainder of 344.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 2394 away from 2738, we end up with 344.
Take the next digit (7) from the dividend and append it to 344, then repeat: 3447 / 399

Step 5:
399 can be fit into 3447 8 times, resulting in a remainder of 255.
Use 8 as the next digit of our solution. 
Result so far: 168.0
If we subtract 3192 from 3447, we get 255.
Take the next digit (4) from the dividend and append it to 255, then repeat: 2554 / 399

Step 6:
2554 divided by 399 is 6 with a remainder of 160.
The next digit of our result is 6. 
Result so far: 1686.0
Subtracting 2394 from 2554 leaves us with 160.
Take the next digit (1) from the dividend and append it to 160, then repeat: 1601 / 399

Advancing to step 7:
The number 399 fits into 1601 4 times, leaving a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 16864.0
Subtracting 1596 from 1601 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 399

Let's proceed to step 8:
59 divided by 399 is 0 with a remainder of 59.
The next digit of our result is 0. 
Result so far: 168640.0
Deduct 0 from 59 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
When dividing 590 by 399, we get 1 with a remainder of 191.
Put 1 as the next digit of the answer. 
Result so far: 168640.1
Subtract 399 from 590 to get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Going ahead to step 10:
When dividing 1910 by 399, we get 4 with a remainder of 314.
Write down 4 as next digit of the result. 
Result so far: 168640.14
Subtract 1596 from 1910 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 11:
The number 399 fits into 3140 7 times, leaving a remainder of 347.
Use 7 as the next digit of our solution. 
Result so far: 168640.147
If we take 2793 away from 3140, we end up with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Going ahead to step 12:
399 goes into 3470 8 times with a remainder of 278.
Use 8 as the next digit of our solution. 
Result so far: 168640.1478
Subtracting 3192 from 3470 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 13:
2780 divided by 399 is 6 with a remainder of 386.
Write down 6 as next digit of the result. 
Result so far: 168640.14786
Subtracting 2394 from 2780 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 14:
If we divide 3860 by 399, we get 9 and a remainder of 269.
Record the quotient 9 as the next digit in the result. 
Result so far: 168640.147869
Subtracting 3591 from 3860 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Going ahead to step 15:
399 goes into 2690 6 times with a remainder of 296.
Record the quotient 6 as the next digit in the result. 
Result so far: 168640.1478696
Subtract 2394 from 2690 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 16:
2960 divided by 399 is 7 with a remainder of 167.
Put 7 as the next digit of the answer. 
Result so far: 168640.14786967
Subtract 2793 from 2960 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

The final outcome is 168640.14786967, with a leftover of 1.67e-07.
