We're dividing 152502 by 12 
Our goal is to divide 152502 by 12.

On to step 1:
12 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 12

On to step 2:
12 goes into 15 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 12 from 15 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 12

Moving on to step 3:
12 goes into 32 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 24 away from 32, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 12

Moving on to step 4:
85 divided by 12 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
If we subtract 84 from 85, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 12

Advancing to step 5:
12 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1270.0
If we subtract 0 from 10, we get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 12

Step 6:
12 goes into 102 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 12708.0
If we take 96 away from 102, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
When dividing 60 by 12, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12708.5
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.

Advancing to step 8:
0 divided by 12 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12708.5
If we subtract 0 from 0, we 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 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12708.5
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 12708.5 with a remaining 0.0.
