We look at the division of 488154 by 39 
Let's see how many times 39 fits into 488154.

Step 1:
39 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 39

On to step 2:
39 can be fit into 48 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 9 after subtracting 39 from 48.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 39

Let's proceed to step 3:
When dividing 98 by 39, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 20 after subtracting 78 from 98.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 39

Step 4:
201 divided by 39 is 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 125.0
If we take 195 away from 201, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 39

Let's proceed to step 5:
If we divide 65 by 39, we get 1 and a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1251.0
Subtracting 39 from 65 leaves us with 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 39

Advancing to step 6:
39 can be fit into 264 6 times, resulting in a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 12516.0
The remainder is 30 after subtracting 234 from 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
When dividing 300 by 39, we get 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 12516.7
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
39 can be fit into 270 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 12516.76
Subtracting 234 from 270 leaves us 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.

Going ahead to step 9:
39 goes into 360 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 12516.769
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.

Let's proceed to step 10:
39 can be fit into 90 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 12516.7692
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
When dividing 120 by 39, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 12516.76923
Deduct 117 from 120 and we're left 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 12:
39 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 12516.76923
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.

Moving on to step 13:
If we divide 300 by 39, we get 7 and a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 12516.7692307
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 14:
The number 39 fits into 270 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 12516.76923076
If we subtract 234 from 270, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 12516.76923076, with a leftover of 3.6e-08.
