We're dividing 839853 by 39 
Our goal is to divide 839853 by 39.

On to step 1:
If we divide 8 by 39, we get 0 and 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.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 39

Step 2:
When dividing 83 by 39, we get 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 78 from 83 to get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 39

Advancing to step 3:
If we divide 59 by 39, we get 1 and 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.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 39

On to step 4:
208 divided by 39 is 5 with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
Subtracting 195 from 208 leaves us with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 39

Advancing to step 5:
When dividing 135 by 39, we get 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 2153.0
If we subtract 117 from 135, we get 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 39

Going ahead to step 6:
183 divided by 39 is 4 with a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 21534.0
If we subtract 156 from 183, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
When dividing 270 by 39, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 21534.6
Subtracting 234 from 270 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
When dividing 360 by 39, we get 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 21534.69
If we subtract 351 from 360, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
If we divide 90 by 39, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 21534.692
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
The number 39 fits into 120 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 21534.6923
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
30 divided by 39 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 21534.6923
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
300 divided by 39 is 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 21534.692307
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
39 goes into 270 6 times with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 21534.6923076
Subtract 234 from 270 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
If we divide 360 by 39, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 21534.69230769
Subtract 351 from 360 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 21534.69230769 with a remainder of 9e-09.
