We divide 672458 by 12
Our goal is to divide 672458 by 12.

Step 1:
6 divided by 12 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 12

Advancing to step 2:
When dividing 67 by 12, we get 5 with a remainder of 7.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 7 after subtracting 60 from 67.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 12

Moving on to step 3:
72 divided by 12 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 56.0
If we subtract 72 from 72, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 12

Going ahead to step 4:
12 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 560.0
Subtract 0 from 4 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 12

Moving on to step 5:
12 can be fit into 45 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 5603.0
Subtract 36 from 45 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 12

Advancing to step 6:
12 goes into 98 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 56038.0
Deduct 96 from 98 and we're left 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.

Step 7:
When dividing 20 by 12, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 56038.1
Subtract 12 from 20 to get 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 8:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 56038.16
Deduct 72 from 80 and we're left 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.

Moving on to step 9:
12 goes into 80 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 56038.166
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 56038.166, with a leftover of 0.0008.
