We look at the division of 840501 by 12 
Our goal is to divide 840501 by 12.

Let's proceed to step 1:
When dividing 8 by 12, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 12

Going ahead to step 2:
When dividing 84 by 12, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 84 from 84, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 12

On to step 3:
If we divide 0 by 12, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 70.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 12

Moving on to step 4:
12 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 700.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 12

Step 5:
50 divided by 12 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 7004.0
Deduct 48 from 50 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 12

Step 6:
When dividing 21 by 12, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 70041.0
The remainder is 9 after subtracting 12 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
12 can be fit into 90 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 70041.7
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
12 can be fit into 60 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 70041.75
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 70041.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 70041.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 70041.75 with a remaining 0.0.
