Let's divide 488734 by 39
Our goal is to divide 488734 by 39.

Step 1:
39 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 39

Advancing to step 2:
If we divide 48 by 39, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 39 from 48, we get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 39

Moving on to step 3:
The number 39 fits into 98 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 78 from 98 leaves us with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 39

Step 4:
207 divided by 39 is 5 with a remainder of 12.
The next digit of our result is 5. 
Result so far: 125.0
The remainder is 12 after subtracting 195 from 207.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 39

Moving on to step 5:
39 can be fit into 123 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 1253.0
Subtract 117 from 123 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 39

Going ahead to step 6:
39 can be fit into 64 1 times, resulting in a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 12531.0
The remainder is 25 after subtracting 39 from 64.
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 7:
When dividing 250 by 39, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 12531.6
Deduct 234 from 250 and we're left 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.

Step 8:
39 goes into 160 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 12531.64
Deduct 156 from 160 and we're left 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.

Moving on to step 9:
When dividing 40 by 39, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 12531.641
If we take 39 away from 40, we end up 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.

Moving on to step 10:
When dividing 10 by 39, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 12531.641
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.

Advancing to step 11:
When dividing 100 by 39, we get 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 12531.64102
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
39 can be fit into 220 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 12531.641025
Subtracting 195 from 220 leaves us 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 13:
39 can be fit into 250 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 12531.6410256
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.

Advancing to step 14:
39 can be fit into 160 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 12531.64102564
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.

The final outcome is 12531.64102564, with a leftover of 4e-09.
