507750 ÷ 39 
We want to divide 507750 by 39.

On to step 1:
If we divide 5 by 39, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 39

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
Subtracting 39 from 50 leaves us with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 39

Moving on to step 3:
39 goes into 117 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 117 from 117 to get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 39

Step 4:
When dividing 7 by 39, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 130.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 39

Moving on to step 5:
The number 39 fits into 75 1 times, leaving a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 1301.0
Subtracting 39 from 75 leaves us with 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 39

Let's proceed to step 6:
39 can be fit into 360 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 13019.0
The remainder is 9 after subtracting 351 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
The number 39 fits into 90 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 13019.2
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
When dividing 120 by 39, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 13019.23
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
30 divided by 39 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 13019.23
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
If we divide 300 by 39, we get 7 and a remainder of 27.
The next digit of our result is 7. 
Result so far: 13019.2307
Subtracting 273 from 300 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 11:
39 goes into 270 6 times with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 13019.23076
Deduct 234 from 270 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
If we divide 360 by 39, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 13019.230769
Subtracting 351 from 360 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
90 divided by 39 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 13019.2307692
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
39 goes into 120 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 13019.23076923
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 13019.23076923 with a remaining 3e-09.
