Let's divide 86425560 by 12
We're looking to find how many times 12 goes into 86425560.

Step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 12

Let's proceed to step 2:
12 goes into 86 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 2 after subtracting 84 from 86.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 12

On to step 3:
The number 12 fits into 24 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 0 after subtracting 24 from 24.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 12

Step 4:
When dividing 2 by 12, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 720.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 12

Step 5:
The number 12 fits into 25 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 7202.0
Deduct 24 from 25 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 12

Advancing to step 6:
The number 12 fits into 15 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 72021.0
The remainder is 3 after subtracting 12 from 15.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 12

On to step 7:
36 divided by 12 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 720213.0
Subtract 36 from 36 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 12

Let's proceed to step 8:
12 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7202130.0
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 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7202130.0
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.

Moving on to step 10:
12 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7202130.0
Subtract 0 from 0 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.

The quotient of the division is 7202130.0, and the remainder is 0.0.
