Let's divide 870540 by 12
We want to figure out the number of times 870540 can be divided by 12.

Going ahead to step 1:
When dividing 8 by 12, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 12

Step 2:
If we divide 87 by 12, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 84 from 87 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 12

Step 3:
The number 12 fits into 30 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Deduct 24 from 30 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 12

Going ahead to step 4:
When dividing 65 by 12, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 725.0
Deduct 60 from 65 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 12

Advancing to step 5:
12 goes into 54 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 7254.0
The remainder is 6 after subtracting 48 from 54.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 12

Moving on to step 6:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 72545.0
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.

Moving on to step 7:
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: 72545.0
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.

Let's proceed to step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 72545.0
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.

The quotient of the division is 72545.0, and the remainder is 0.0.
