Let's divide 50564012 by 399
We're looking to find how many times 399 goes into 50564012.

Let's proceed to step 1:
If we divide 5 by 399, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 399

Let's proceed to step 2:
399 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 399

Let's proceed to step 3:
The number 399 fits into 505 1 times, leaving a remainder of 106.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 399 from 505 and we're left with 106.
Take the next digit (6) from the dividend and append it to 106, then repeat: 1066 / 399

Let's proceed to step 4:
When dividing 1066 by 399, we get 2 with a remainder of 268.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 268 after subtracting 798 from 1066.
Take the next digit (4) from the dividend and append it to 268, then repeat: 2684 / 399

On to step 5:
When dividing 2684 by 399, we get 6 with a remainder of 290.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
The remainder is 290 after subtracting 2394 from 2684.
Take the next digit (0) from the dividend and append it to 290, then repeat: 2900 / 399

Advancing to step 6:
399 can be fit into 2900 7 times, resulting in a remainder of 107.
The number 7 becomes the next digit in our result. 
Result so far: 1267.0
Deduct 2793 from 2900 and we're left with 107.
Bring next digit (1) of the dividend behind the 107 and repeat the process: 1071 / 399

On to step 7:
399 can be fit into 1071 2 times, resulting in a remainder of 273.
Record the quotient 2 as the next digit in the result. 
Result so far: 12672.0
Subtracting 798 from 1071 leaves us with 273.
Take the next digit (2) from the dividend and append it to 273, then repeat: 2732 / 399

Moving on to step 8:
399 can be fit into 2732 6 times, resulting in a remainder of 338.
Write down 6 as next digit of the result. 
Result so far: 126726.0
If we take 2394 away from 2732, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Step 9:
The number 399 fits into 3380 8 times, leaving a remainder of 188.
The number 8 becomes the next digit in our result. 
Result so far: 126726.8
Subtract 3192 from 3380 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 10:
The number 399 fits into 1880 4 times, leaving a remainder of 284.
Record the quotient 4 as the next digit in the result. 
Result so far: 126726.84
Subtracting 1596 from 1880 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 11:
When dividing 2840 by 399, we get 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 126726.847
Deduct 2793 from 2840 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 12:
The number 399 fits into 470 1 times, leaving a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 126726.8471
If we subtract 399 from 470, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 13:
If we divide 710 by 399, we get 1 and a remainder of 311.
Write down 1 as next digit of the result. 
Result so far: 126726.84711
The remainder is 311 after subtracting 399 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

The quotient of the division is 126726.84711, and the remainder is 0.000311.
