839965 ÷ 39 
We want to divide 839965 by 39.

Step 1:
8 divided by 39 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 39

Step 2:
The number 39 fits into 83 2 times, leaving a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 5 after subtracting 78 from 83.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 39

Going ahead to step 3:
When dividing 59 by 39, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 20 after subtracting 39 from 59.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 39

Let's proceed to step 4:
39 goes into 209 5 times with a remainder of 14.
The next digit of our result is 5. 
Result so far: 215.0
If we take 195 away from 209, we end up with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 39

Let's proceed to step 5:
If we divide 146 by 39, we get 3 and a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 2153.0
If we subtract 117 from 146, we get 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 39

Moving on to step 6:
39 goes into 295 7 times with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 21537.0
Deduct 273 from 295 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 7:
If we divide 220 by 39, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 21537.5
If we take 195 away from 220, we end up 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 8:
39 goes into 250 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 21537.56
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.

Advancing to step 9:
The number 39 fits into 160 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 21537.564
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.

Going ahead to step 10:
The number 39 fits into 40 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 21537.5641
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 11:
10 divided by 39 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 21537.5641
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 12:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 21537.564102
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 13:
The number 39 fits into 220 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 21537.5641025
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.

Advancing to step 14:
39 can be fit into 250 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 21537.56410256
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.

The final outcome is 21537.56410256, with a leftover of 1.6e-08.
