585447 divided by 12 
We want to figure out the number of times 585447 can be divided by 12.

Step 1:
When dividing 5 by 12, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 12

Let's proceed to step 2:
12 goes into 58 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 10 after subtracting 48 from 58.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 12

Let's proceed to step 3:
12 can be fit into 105 8 times, resulting in a remainder of 9.
The next digit of our result is 8. 
Result so far: 48.0
The remainder is 9 after subtracting 96 from 105.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 12

Advancing to step 4:
12 can be fit into 94 7 times, resulting in a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 487.0
If we take 84 away from 94, we end up with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 12

Advancing to step 5:
104 divided by 12 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 4878.0
Deduct 96 from 104 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 12

Advancing to step 6:
12 goes into 87 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 48787.0
Deduct 84 from 87 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
12 goes into 30 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 48787.2
Subtracting 24 from 30 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 12 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 48787.25
If we take 60 away from 60, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 48787.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 48787.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 48787.25, and the remainder is 0.0.
