489807 divided by 39 
We're looking to find how many times 39 goes into 489807.

Step 1:
When dividing 4 by 39, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 39

Let's proceed to step 2:
When dividing 48 by 39, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 39 from 48 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 39

Let's proceed to step 3:
When dividing 99 by 39, we get 2 with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 78 away from 99, we end up with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 39

On to step 4:
The number 39 fits into 218 5 times, leaving a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 125.0
The remainder is 23 after subtracting 195 from 218.
Append the next digit (0) from the dividend to 23 and continue with: 230 / 39

Going ahead to step 5:
When dividing 230 by 39, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1255.0
If we take 195 away from 230, we end up with 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 39

On to step 6:
39 can be fit into 357 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 12559.0
Subtracting 351 from 357 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
When dividing 60 by 39, we get 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 12559.1
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.

Going ahead to step 8:
The number 39 fits into 210 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 12559.15
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 9:
When dividing 150 by 39, we get 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 12559.153
Deduct 117 from 150 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 10:
39 can be fit into 330 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 12559.1538
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
The number 39 fits into 180 4 times, leaving a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 12559.15384
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
39 can be fit into 240 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 12559.153846
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
60 divided by 39 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 12559.1538461
Subtracting 39 from 60 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 14:
The number 39 fits into 210 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 12559.15384615
If we take 195 away from 210, we end up 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.

The final outcome is 12559.15384615, with a leftover of 1.5e-08.
