We look at the division of 12839014 by 806 
Let's see how many times 806 fits into 12839014.

Advancing to step 1:
The number 806 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 806

Advancing to step 2:
If we divide 12 by 806, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 806

Advancing to step 3:
When dividing 128 by 806, we get 0 with a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 128 and we're left with 128.
Append the next digit (3) from the dividend to 128 and continue with: 1283 / 806

Let's proceed to step 4:
If we divide 1283 by 806, we get 1 and a remainder of 477.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 806 away from 1283, we end up with 477.
Fetch the next digit (9) from the dividend, attach it to 477 and continue: 4779 / 806

Step 5:
806 can be fit into 4779 5 times, resulting in a remainder of 749.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 4030 from 4779, we get 749.
Append the next digit (0) from the dividend to 749 and continue with: 7490 / 806

Step 6:
If we divide 7490 by 806, we get 9 and a remainder of 236.
Use 9 as the next digit of our solution. 
Result so far: 159.0
Deduct 7254 from 7490 and we're left with 236.
Fetch the next digit (1) from the dividend, attach it to 236 and continue: 2361 / 806

Advancing to step 7:
If we divide 2361 by 806, we get 2 and a remainder of 749.
The next digit of our result is 2. 
Result so far: 1592.0
The remainder is 749 after subtracting 1612 from 2361.
Take the next digit (4) from the dividend and append it to 749, then repeat: 7494 / 806

Let's proceed to step 8:
If we divide 7494 by 806, we get 9 and a remainder of 240.
Put 9 as the next digit of the answer. 
Result so far: 15929.0
If we subtract 7254 from 7494, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 9:
2400 divided by 806 is 2 with a remainder of 788.
Put 2 as the next digit of the answer. 
Result so far: 15929.2
The remainder is 788 after subtracting 1612 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Advancing to step 10:
The number 806 fits into 7880 9 times, leaving a remainder of 626.
The next digit of our result is 9. 
Result so far: 15929.29
If we take 7254 away from 7880, we end up with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Going ahead to step 11:
6260 divided by 806 is 7 with a remainder of 618.
Write down 7 as next digit of the result. 
Result so far: 15929.297
The remainder is 618 after subtracting 5642 from 6260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Moving on to step 12:
When dividing 6180 by 806, we get 7 with a remainder of 538.
The next digit of our result is 7. 
Result so far: 15929.2977
The remainder is 538 after subtracting 5642 from 6180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

The quotient of the division is 15929.2977, and the remainder is 0.00538.
