Let's divide 844399 by 39
We want to figure out the number of times 844399 can be divided by 39.

On to step 1:
39 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 39

Moving on to step 2:
84 divided by 39 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 78 from 84, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 39

On to step 3:
39 can be fit into 64 1 times, resulting in a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 25 after subtracting 39 from 64.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 39

On to step 4:
39 goes into 253 6 times with a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 216.0
Deduct 234 from 253 and we're left with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 39

Let's proceed to step 5:
When dividing 199 by 39, we get 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 2165.0
If we subtract 195 from 199, we get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 39

Going ahead to step 6:
The number 39 fits into 49 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 21651.0
If we take 39 away from 49, 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 7:
100 divided by 39 is 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 21651.2
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.

Advancing to step 8:
If we divide 220 by 39, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 21651.25
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.

Let's proceed to step 9:
250 divided by 39 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 21651.256
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 10:
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: 21651.2564
If we subtract 156 from 160, we 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.

On to step 11:
40 divided by 39 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 21651.25641
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
The number 39 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 21651.25641
Deduct 0 from 10 and we're left 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.

On to step 13:
The number 39 fits into 100 2 times, leaving a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 21651.2564102
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.

On to step 14:
39 can be fit into 220 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 21651.25641025
The remainder is 25 after subtracting 195 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 21651.25641025 and a remainder of 2.5e-08.
