Let's divide 521514 by 39
We want to figure out the number of times 521514 can be divided by 39.

Advancing to step 1:
5 divided by 39 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 39

Step 2:
39 can be fit into 52 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 39 from 52 leaves us with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 39

Going ahead to step 3:
131 divided by 39 is 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 117 from 131 and we're left with 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 39

Step 4:
If we divide 145 by 39, we get 3 and a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 133.0
If we take 117 away from 145, we end up with 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 39

Going ahead to step 5:
If we divide 281 by 39, we get 7 and a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 1337.0
Subtract 273 from 281 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 39

Advancing to step 6:
If we divide 84 by 39, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 13372.0
The remainder is 6 after subtracting 78 from 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
39 goes into 60 1 times with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 13372.1
Subtracting 39 from 60 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
When dividing 210 by 39, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 13372.15
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
39 can be fit into 150 3 times, resulting in a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 13372.153
Subtracting 117 from 150 leaves us with 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 10:
39 can be fit into 330 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 13372.1538
Subtract 312 from 330 to get 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 11:
39 can be fit into 180 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 13372.15384
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 13372.153846
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
The number 39 fits into 60 1 times, leaving a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 13372.1538461
Deduct 39 from 60 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 14:
39 can be fit into 210 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 13372.15384615
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 13372.15384615, and the remainder is 1.5e-08.
