470509 ÷ 39 
We want to figure out the number of times 470509 can be divided by 39.

Advancing to step 1:
The number 39 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 39

Moving on to step 2:
39 can be fit into 47 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 39 from 47, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 39

Advancing to step 3:
If we divide 80 by 39, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 78 from 80 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 39

Moving on to step 4:
39 can be fit into 25 0 times, resulting in a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 39

Advancing to step 5:
When dividing 250 by 39, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 1206.0
If we subtract 234 from 250, we get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 39

Step 6:
The number 39 fits into 169 4 times, leaving a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 12064.0
The remainder is 13 after subtracting 156 from 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
If we divide 130 by 39, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 12064.3
Deduct 117 from 130 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
When dividing 130 by 39, we get 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 12064.33
If we subtract 117 from 130, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 12064.33 with a remaining 0.013.
