Let's divide 487850 by 39
We're looking to find how many times 39 goes into 487850.

Let's proceed to step 1:
4 divided by 39 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 39

Let's proceed 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
Deduct 39 from 48 and we're left with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 39

Moving on to step 3:
If we divide 97 by 39, we get 2 and a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 19 after subtracting 78 from 97.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 39

Advancing to step 4:
198 divided by 39 is 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 125.0
Deduct 195 from 198 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 39

Going ahead to step 5:
35 divided by 39 is 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 1250.0
If we take 0 away from 35, we end up with 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 39

Moving on to step 6:
The number 39 fits into 350 8 times, leaving a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 12508.0
Subtract 312 from 350 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
380 divided by 39 is 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 12508.9
Deduct 351 from 380 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 8:
The number 39 fits into 290 7 times, leaving a remainder of 17.
The next digit of our result is 7. 
Result so far: 12508.97
Subtract 273 from 290 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
When dividing 170 by 39, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 12508.974
If we subtract 156 from 170, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
39 goes into 140 3 times with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 12508.9743
The remainder is 23 after subtracting 117 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
39 goes into 230 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 12508.97435
If we take 195 away from 230, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
The number 39 fits into 350 8 times, leaving a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 12508.974358
If we take 312 away from 350, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 12508.9743589
If we take 351 away from 380, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 14:
The number 39 fits into 290 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 12508.97435897
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 12508.97435897 and a remainder of 1.7e-08.
