We divide 566839 by 12
Our goal is to divide 566839 by 12.

Going ahead to step 1:
If we divide 5 by 12, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 12

Step 2:
12 goes into 56 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 48 from 56 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 12

Moving on to step 3:
12 goes into 86 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 84 from 86 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 12

On to step 4:
The number 12 fits into 28 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 472.0
Deduct 24 from 28 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 12

Moving on to step 5:
43 divided by 12 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 4723.0
Subtract 36 from 43 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 12

Step 6:
12 goes into 79 6 times with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 47236.0
Subtracting 72 from 79 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
If we divide 70 by 12, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 47236.5
Subtract 60 from 70 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 12, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 47236.58
Subtracting 96 from 100 leaves us 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.

Step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 47236.583
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.

On to step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 47236.5833
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.

After the division, we end up with 47236.5833 and a remainder of 4e-05.
