Let's divide 504813 by 39
We're looking to find how many times 39 goes into 504813.

Advancing to step 1:
39 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 39

Let's proceed to step 2:
39 goes into 50 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 39 from 50 to get 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 39

Going ahead to step 3:
When dividing 114 by 39, we get 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 78 from 114, we get 36.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 39

Let's proceed to step 4:
The number 39 fits into 368 9 times, leaving a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Subtract 351 from 368 to get 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 39

On to step 5:
The number 39 fits into 171 4 times, leaving a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 1294.0
Subtracting 156 from 171 leaves us with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 39

Going ahead to step 6:
39 goes into 153 3 times with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 12943.0
If we take 117 away from 153, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
39 can be fit into 360 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 12943.9
Subtract 351 from 360 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
If we divide 90 by 39, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 12943.92
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
If we divide 120 by 39, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 12943.923
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
39 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 12943.923
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
39 goes into 300 7 times with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 12943.92307
Subtracting 273 from 300 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 12:
39 can be fit into 270 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 12943.923076
Subtracting 234 from 270 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
39 can be fit into 360 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 12943.9230769
Subtract 351 from 360 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 14:
39 can be fit into 90 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 12943.92307692
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 12943.92307692, with a leftover of 1.2e-08.
