520254 ÷ 39 
We want to figure out the number of times 520254 can be divided by 39.

On to step 1:
When dividing 5 by 39, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 39

Let's proceed to step 2:
When dividing 52 by 39, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 39 away from 52, we end up with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 39

Let's proceed to step 3:
When dividing 130 by 39, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 117 from 130 and we're left with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 39

On to step 4:
If we divide 132 by 39, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
Subtract 117 from 132 to get 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 39

Going ahead to step 5:
155 divided by 39 is 3 with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 1333.0
Subtract 117 from 155 to get 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 39

Let's proceed to step 6:
When dividing 384 by 39, we get 9 with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 13339.0
The remainder is 33 after subtracting 351 from 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
39 goes into 330 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 13339.8
If we take 312 away from 330, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
If we divide 180 by 39, we get 4 and a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 13339.84
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
240 divided by 39 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 13339.846
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
39 can be fit into 60 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 13339.8461
The remainder is 21 after subtracting 39 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
The number 39 fits into 210 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 13339.84615
Deduct 195 from 210 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
If we divide 150 by 39, we get 3 and a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 13339.846153
Subtract 117 from 150 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 13:
330 divided by 39 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 13339.8461538
If we take 312 away from 330, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
39 goes into 180 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 13339.84615384
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 13339.84615384, with a leftover of 2.4e-08.
