Let's divide 639850 by 39
Our goal is to divide 639850 by 39.

Advancing to step 1:
When dividing 6 by 39, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 39

Let's proceed to step 2:
If we divide 63 by 39, we get 1 and a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 39 from 63 to get 24.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 39

Step 3:
249 divided by 39 is 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 234 from 249 and we're left with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 39

Step 4:
158 divided by 39 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 164.0
Subtracting 156 from 158 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 39

Let's proceed to step 5:
25 divided by 39 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 1640.0
Subtract 0 from 25 to get 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 39

Moving on to step 6:
When dividing 250 by 39, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 16406.0
Subtract 234 from 250 to 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.

Moving on to step 7:
When dividing 160 by 39, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 16406.4
Subtracting 156 from 160 leaves us 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 8:
39 goes into 40 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 16406.41
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.

Step 9:
39 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 16406.41
If we subtract 0 from 10, we get 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 10:
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: 16406.4102
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.

Moving on to step 11:
If we divide 220 by 39, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 16406.41025
If we subtract 195 from 220, we 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.

Let's proceed to step 12:
39 can be fit into 250 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 16406.410256
Deduct 234 from 250 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
If we divide 160 by 39, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 16406.4102564
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
If we divide 40 by 39, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 16406.41025641
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.

After the division, we end up with 16406.41025641 and a remainder of 1e-09.
