501803 divided by 12 
Our goal is to divide 501803 by 12.

On to step 1:
12 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 12

Let's proceed to step 2:
50 divided by 12 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 48 from 50 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 12

Step 3:
When dividing 21 by 12, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 12 from 21 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 12

Advancing to step 4:
12 goes into 98 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 418.0
Subtracting 96 from 98 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 12

Going ahead to step 5:
20 divided by 12 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 4181.0
Subtract 12 from 20 to get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 12

Going ahead to step 6:
The number 12 fits into 83 6 times, leaving a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 41816.0
Subtract 72 from 83 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
When dividing 110 by 12, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 41816.9
Subtracting 108 from 110 leaves us 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.

On to step 8:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 41816.91
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.

Advancing to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 41816.916
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.

Going ahead to step 10:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 41816.9166
Subtracting 72 from 80 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.

After the division, we end up with 41816.9166 and a remainder of 8e-05.
