We're dividing 503340 by 39 
We want to figure out the number of times 503340 can be divided by 39.

Let's proceed to step 1:
If we divide 5 by 39, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 39

Going ahead to step 2:
50 divided by 39 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 39 from 50, we get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 39

Moving on to step 3:
When dividing 113 by 39, we get 2 with a remainder of 35.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 78 from 113 to get 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 39

Going ahead to step 4:
When dividing 353 by 39, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
Deduct 351 from 353 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 39

Going ahead to step 5:
The number 39 fits into 24 0 times, leaving a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 1290.0
Subtract 0 from 24 to get 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 39

Let's proceed to step 6:
When dividing 240 by 39, we get 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 12906.0
If we subtract 234 from 240, we 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 7:
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: 12906.1
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.

On to step 8:
39 goes into 210 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 12906.15
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.

On to step 9:
150 divided by 39 is 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 12906.153
The remainder is 33 after subtracting 117 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing 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: 12906.1538
If we subtract 312 from 330, we 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:
If we divide 180 by 39, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 12906.15384
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.

Going ahead to step 12:
When dividing 240 by 39, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 12906.153846
Deduct 234 from 240 and we're left 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.

Moving on to step 13:
If we divide 60 by 39, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 12906.1538461
If we take 39 away from 60, we end up 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.

Step 14:
39 can be fit into 210 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 12906.15384615
If we subtract 195 from 210, we 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 final result is 12906.15384615 with a remainder of 1.5e-08.
