We divide 577397 by 12
Our goal is to divide 577397 by 12.

Step 1:
12 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 12

Advancing to step 2:
When dividing 57 by 12, we get 4 with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 48 from 57 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 12

On to step 3:
12 can be fit into 97 8 times, resulting in a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Deduct 96 from 97 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 12

Step 4:
The number 12 fits into 13 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 481.0
Subtract 12 from 13 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 12

Advancing to step 5:
The number 12 fits into 19 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 4811.0
Deduct 12 from 19 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 12

Advancing to step 6:
The number 12 fits into 77 6 times, leaving a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 48116.0
If we take 72 away from 77, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
50 divided by 12 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 48116.4
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
When dividing 20 by 12, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 48116.41
Subtracting 12 from 20 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 48116.416
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.

Step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 48116.4166
If we take 72 away from 80, we end up with 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 48116.4166, and the remainder is 8e-05.
