We look at the division of 12709391 by 672 
We want to figure out the number of times 12709391 can be divided by 672.

Step 1:
1 divided by 672 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 672

On to step 2:
The number 672 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 672

On to step 3:
127 divided by 672 is 0 with a remainder of 127.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 127 leaves us with 127.
Fetch the next digit (0) from the dividend, attach it to 127 and continue: 1270 / 672

On to step 4:
672 can be fit into 1270 1 times, resulting in a remainder of 598.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 672 from 1270 to get 598.
Take the next digit (9) from the dividend and append it to 598, then repeat: 5989 / 672

On to step 5:
672 goes into 5989 8 times with a remainder of 613.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 5376 from 5989 to get 613.
Take the next digit (3) from the dividend and append it to 613, then repeat: 6133 / 672

Going ahead to step 6:
If we divide 6133 by 672, we get 9 and a remainder of 85.
The number 9 becomes the next digit in our result. 
Result so far: 189.0
Subtract 6048 from 6133 to get 85.
Include the next digit (9) from the dividend after 85, then repeat: 859 / 672

Moving on to step 7:
The number 672 fits into 859 1 times, leaving a remainder of 187.
Write down 1 as next digit of the result. 
Result so far: 1891.0
The remainder is 187 after subtracting 672 from 859.
Append the next digit (1) from the dividend to 187 and continue with: 1871 / 672

Moving on to step 8:
672 can be fit into 1871 2 times, resulting in a remainder of 527.
Use 2 as the next digit of our solution. 
Result so far: 18912.0
Deduct 1344 from 1871 and we're left with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Going ahead to step 9:
If we divide 5270 by 672, we get 7 and a remainder of 566.
The next digit of our result is 7. 
Result so far: 18912.7
Deduct 4704 from 5270 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Advancing to step 10:
672 goes into 5660 8 times with a remainder of 284.
The number 8 becomes the next digit in our result. 
Result so far: 18912.78
The remainder is 284 after subtracting 5376 from 5660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 11:
672 can be fit into 2840 4 times, resulting in a remainder of 152.
Write down 4 as next digit of the result. 
Result so far: 18912.784
If we take 2688 away from 2840, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 12:
The number 672 fits into 1520 2 times, leaving a remainder of 176.
Record the quotient 2 as the next digit in the result. 
Result so far: 18912.7842
If we subtract 1344 from 1520, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 13:
The number 672 fits into 1760 2 times, leaving a remainder of 416.
Write down 2 as next digit of the result. 
Result so far: 18912.78422
If we subtract 1344 from 1760, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The quotient of the division is 18912.78422, and the remainder is 0.000416.
