521977 divided by 12 
Our goal is to divide 521977 by 12.

Advancing to step 1:
If we divide 5 by 12, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 12

Let's proceed to step 2:
52 divided by 12 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 48 from 52, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 12

Going ahead to step 3:
If we divide 41 by 12, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtract 36 from 41 to get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 12

On to step 4:
59 divided by 12 is 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 434.0
Subtracting 48 from 59 leaves us with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 12

Advancing to step 5:
117 divided by 12 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 4349.0
If we subtract 108 from 117, we get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 12

Step 6:
If we divide 97 by 12, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 43498.0
Deduct 96 from 97 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 12 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 43498.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 12 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 43498.08
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 43498.083
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
12 goes into 40 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 43498.0833
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 43498.0833, and the remainder is 4e-05.
