Let's divide 863929 by 39
We want to divide 863929 by 39.

Advancing to step 1:
When dividing 8 by 39, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 39

Let's proceed to step 2:
When dividing 86 by 39, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 78 away from 86, we end up with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 39

Going ahead to step 3:
39 goes into 83 2 times with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 78 from 83, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 39

On to step 4:
When dividing 59 by 39, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 221.0
Subtracting 39 from 59 leaves us with 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 39

Going ahead to step 5:
If we divide 202 by 39, we get 5 and a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 2215.0
The remainder is 7 after subtracting 195 from 202.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 39

On to step 6:
79 divided by 39 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 22152.0
If we subtract 78 from 79, we get 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 7:
39 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 22152.0
If we take 0 away from 10, we end up 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 8:
100 divided by 39 is 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 22152.02
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
If we divide 220 by 39, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 22152.025
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.

Advancing to step 10:
If we divide 250 by 39, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 22152.0256
The remainder is 16 after subtracting 234 from 250.
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:
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: 22152.02564
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
The number 39 fits into 40 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 22152.025641
Subtracting 39 from 40 leaves us 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 13:
If we divide 10 by 39, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 22152.025641
Subtract 0 from 10 to 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.

On to step 14:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 22152.02564102
Subtract 78 from 100 to 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.

The final result is 22152.02564102 with a remainder of 2.2e-08.
