We look at the division of 984859 by 12 
Our goal is to divide 984859 by 12.

On to step 1:
If we divide 9 by 12, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 12

On to step 2:
12 goes into 98 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 96 away from 98, we end up with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 12

On to step 3:
If we divide 24 by 12, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we subtract 24 from 24, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 12

Advancing to step 4:
If we divide 8 by 12, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 820.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 12

Going ahead to step 5:
12 can be fit into 85 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 8207.0
Subtract 84 from 85 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 12

Going ahead to step 6:
12 goes into 19 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 82071.0
Deduct 12 from 19 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
12 goes into 70 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 82071.5
If we take 60 away from 70, 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.

On to step 8:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 82071.58
Subtracting 96 from 100 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 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 82071.583
Subtract 36 from 40 to 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.

Moving on to step 10:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 82071.5833
If we subtract 36 from 40, 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.

Our division results in 82071.5833 with a remaining 4e-05.
