Let's divide 862521 by 12
We're looking to find how many times 12 goes into 862521.

On to step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 12

Step 2:
When dividing 86 by 12, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 84 from 86 leaves us with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 12

On to step 3:
If we divide 22 by 12, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 71.0
Subtract 12 from 22 to get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 12

Advancing to step 4:
105 divided by 12 is 8 with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 718.0
The remainder is 9 after subtracting 96 from 105.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 12

Going ahead to step 5:
When dividing 92 by 12, we get 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 7187.0
The remainder is 8 after subtracting 84 from 92.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 12

On to step 6:
The number 12 fits into 81 6 times, leaving a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 71876.0
The remainder is 9 after subtracting 72 from 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
90 divided by 12 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 71876.7
Subtract 84 from 90 to 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:
When dividing 60 by 12, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 71876.75
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 71876.75
If we take 0 away from 0, we end up 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.

Going ahead to step 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 71876.75
The remainder is 0 after subtracting 0 from 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 71876.75 with a remaining 0.0.
