We divide 523513 by 39
We want to figure out the number of times 523513 can be divided by 39.

Moving on to step 1:
When dividing 5 by 39, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 39

Going ahead to step 2:
39 can be fit into 52 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 39 from 52 to get 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 39

Let's proceed to step 3:
When dividing 133 by 39, we get 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 13.0
If we take 117 away from 133, we end up with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 39

Going ahead to step 4:
39 goes into 165 4 times with a remainder of 9.
The next digit of our result is 4. 
Result so far: 134.0
The remainder is 9 after subtracting 156 from 165.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 39

On to step 5:
39 goes into 91 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 1342.0
Subtracting 78 from 91 leaves us with 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 39

Let's proceed to step 6:
If we divide 133 by 39, we get 3 and a remainder of 16.
The next digit of our result is 3. 
Result so far: 13423.0
If we subtract 117 from 133, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
When dividing 160 by 39, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 13423.4
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
39 goes into 40 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 13423.41
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
39 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 13423.41
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
100 divided by 39 is 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 13423.4102
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
220 divided by 39 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 13423.41025
If we subtract 195 from 220, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
If we divide 250 by 39, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 13423.410256
If we take 234 away from 250, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
160 divided by 39 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 13423.4102564
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
If we divide 40 by 39, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 13423.41025641
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 13423.41025641, with a leftover of 1e-09.
