863251 divided by 39 
We want to figure out the number of times 863251 can be divided by 39.

On to step 1:
The number 39 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 39

Going ahead to step 2:
When dividing 86 by 39, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 78 from 86 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 39

Moving on to step 3:
If we divide 83 by 39, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 5 after subtracting 78 from 83.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 39

Let's proceed to step 4:
If we divide 52 by 39, we get 1 and a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 221.0
Deduct 39 from 52 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 39

Advancing to step 5:
135 divided by 39 is 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 2213.0
Deduct 117 from 135 and we're left with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 39

On to step 6:
If we divide 181 by 39, we get 4 and a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 22134.0
The remainder is 25 after subtracting 156 from 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
If we divide 250 by 39, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 22134.6
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.

Step 8:
160 divided by 39 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 22134.64
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.

Advancing to step 9:
When dividing 40 by 39, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 22134.641
If we subtract 39 from 40, 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.

Let's proceed to step 10:
39 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 22134.641
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
If we divide 100 by 39, we get 2 and a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 22134.64102
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.

Advancing to step 12:
The number 39 fits into 220 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 22134.641025
Subtracting 195 from 220 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
If we divide 250 by 39, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 22134.6410256
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.

Step 14:
39 can be fit into 160 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 22134.64102564
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.

The quotient of the division is 22134.64102564, and the remainder is 4e-09.
