We're dividing 53388 by 12 
We want to divide 53388 by 12.

Step 1:
5 divided by 12 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 12

Advancing to step 2:
If we divide 53 by 12, we get 4 and a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 5 after subtracting 48 from 53.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 12

On to step 3:
If we divide 53 by 12, we get 4 and a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 44.0
If we subtract 48 from 53, we get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 12

Let's proceed to step 4:
The number 12 fits into 58 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 444.0
If we subtract 48 from 58, we get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 12

Advancing to step 5:
12 can be fit into 108 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 4449.0
Subtract 108 from 108 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.

Step 6:
0 divided by 12 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4449.0
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.

Advancing to step 7:
0 divided by 12 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4449.0
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 4449.0, and the remainder is 0.0.
