We look at the division of 488749 by 39 
We want to figure out the number of times 488749 can be divided by 39.

Step 1:
The number 39 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 39

Moving on to step 2:
39 goes into 48 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 9 after subtracting 39 from 48.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 39

Step 3:
39 can be fit into 98 2 times, resulting in a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 78 from 98 to get 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 39

Advancing to step 4:
207 divided by 39 is 5 with a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Deduct 195 from 207 and we're left with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 39

Let's proceed to step 5:
39 can be fit into 124 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 1253.0
Subtract 117 from 124 to get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 39

Advancing to step 6:
39 goes into 79 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 12532.0
If we take 78 away from 79, 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.

Step 7:
39 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 12532.0
Deduct 0 from 10 and we're left 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.

Let's proceed to step 8:
100 divided by 39 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 12532.02
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
If we divide 220 by 39, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 12532.025
Subtract 195 from 220 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
When dividing 250 by 39, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 12532.0256
If we subtract 234 from 250, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
The number 39 fits into 160 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 12532.02564
If we take 156 away from 160, we end up 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.

On to step 12:
40 divided by 39 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 12532.025641
Deduct 39 from 40 and we're left 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.

Advancing to step 13:
39 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 12532.025641
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.

Moving on to step 14:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 12532.02564102
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 12532.02564102 and a remainder of 2.2e-08.
