We look at the division of 139466 by 9 
We want to divide 139466 by 9.

Moving on to step 1:
9 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 9

Advancing to step 2:
The number 9 fits into 13 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 9 from 13 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 9

On to step 3:
49 divided by 9 is 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 4 after subtracting 45 from 49.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 9

On to step 4:
If we divide 44 by 9, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 154.0
If we take 36 away from 44, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 9

Step 5:
86 divided by 9 is 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 1549.0
If we subtract 81 from 86, we get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 9

Step 6:
If we divide 56 by 9, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 15496.0
If we take 54 away from 56, we end up 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.

Moving on to step 7:
9 goes into 20 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 15496.2
Subtracting 18 from 20 leaves us 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.

On to step 8:
The number 9 fits into 20 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 15496.22
Deduct 18 from 20 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.

The final result is 15496.22 with a remainder of 0.002.
