We look at the division of 53321057 by 12 
Our goal is to divide 53321057 by 12.

Going ahead to step 1:
The number 12 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 12

Step 2:
12 goes into 53 4 times with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 48 from 53, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 12

Let's proceed to step 3:
53 divided by 12 is 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 44.0
If we take 48 away from 53, we end up with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 12

Moving on to step 4:
When dividing 52 by 12, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 444.0
If we subtract 48 from 52, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 12

Step 5:
41 divided by 12 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 4443.0
If we take 36 away from 41, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 12

Moving on to step 6:
When dividing 50 by 12, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 44434.0
Deduct 48 from 50 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 12

Advancing to step 7:
12 can be fit into 25 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 444342.0
Subtracting 24 from 25 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 12

On to step 8:
If we divide 17 by 12, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 4443421.0
Subtract 12 from 17 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
12 can be fit into 50 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4443421.4
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
12 goes into 20 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 4443421.41
If we subtract 12 from 20, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
When dividing 80 by 12, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 4443421.416
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 4443421.4166
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 4443421.4166, and the remainder is 8e-05.
