We're dividing 673887 by 12 
Let's see how many times 12 fits into 673887.

On to step 1:
If we divide 6 by 12, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 12

Let's proceed to step 2:
12 can be fit into 67 5 times, resulting in a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 7 after subtracting 60 from 67.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 12

Step 3:
When dividing 73 by 12, we get 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 56.0
If we take 72 away from 73, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 12

Moving on to step 4:
12 can be fit into 18 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 561.0
If we take 12 away from 18, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 12

Advancing to step 5:
The number 12 fits into 68 5 times, leaving a remainder of 8.
The next digit of our result is 5. 
Result so far: 5615.0
Subtract 60 from 68 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 12

Let's proceed to step 6:
87 divided by 12 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 56157.0
If we take 84 away from 87, we end up 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:
The number 12 fits into 30 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 56157.2
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.

Step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 56157.25
If we subtract 60 from 60, 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.

Let's proceed to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 56157.25
Subtracting 0 from 0 leaves us 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.

Step 10:
12 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 56157.25
Deduct 0 from 0 and we're left 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.

The quotient of the division is 56157.25, and the remainder is 0.0.
