Let's divide 490887 by 39
Our goal is to divide 490887 by 39.

Advancing to step 1:
4 divided by 39 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 39

On to step 2:
If we divide 49 by 39, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 39 from 49, we get 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 39

On to step 3:
If we divide 100 by 39, we get 2 and a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 78 from 100 and we're left with 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 39

Advancing to step 4:
39 goes into 228 5 times with a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 125.0
The remainder is 33 after subtracting 195 from 228.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 39

Moving on to step 5:
The number 39 fits into 338 8 times, leaving a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 1258.0
Subtract 312 from 338 to get 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 39

Let's proceed to step 6:
If we divide 267 by 39, we get 6 and a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 12586.0
The remainder is 33 after subtracting 234 from 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
The number 39 fits into 330 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 12586.8
Deduct 312 from 330 and we're left with 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 8:
180 divided by 39 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 12586.84
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
If we divide 240 by 39, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 12586.846
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
60 divided by 39 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 12586.8461
The remainder is 21 after subtracting 39 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
210 divided by 39 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 12586.84615
Deduct 195 from 210 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
When dividing 150 by 39, we get 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 12586.846153
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 13:
330 divided by 39 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 12586.8461538
Subtracting 312 from 330 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
39 goes into 180 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 12586.84615384
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 12586.84615384, with a leftover of 2.4e-08.
