We divide 503959 by 39
We want to figure out the number of times 503959 can be divided by 39.

On to step 1:
The number 39 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 39

Let's proceed to step 2:
50 divided by 39 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 39 from 50 to get 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 39

Let's proceed to step 3:
The number 39 fits into 113 2 times, leaving a remainder of 35.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 78 from 113 leaves us with 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 39

On to step 4:
39 goes into 359 9 times with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Deduct 351 from 359 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 39

Step 5:
When dividing 85 by 39, we get 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 1292.0
Subtracting 78 from 85 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 39

Let's proceed to step 6:
79 divided by 39 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 12922.0
Deduct 78 from 79 and we're left 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.

On to step 7:
When dividing 10 by 39, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 12922.0
Deduct 0 from 10 and we're left with 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 8:
If we divide 100 by 39, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 12922.02
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
39 goes into 220 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 12922.025
Deduct 195 from 220 and we're left with 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 10:
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: 12922.0256
Subtracting 234 from 250 leaves us 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.

On to step 11:
If we divide 160 by 39, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 12922.02564
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.

Step 12:
39 goes into 40 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 12922.025641
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
If we divide 10 by 39, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 12922.025641
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 12922.02564102
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 12922.02564102 and a remainder of 2.2e-08.
