We divide 400480 by 9
Our goal is to divide 400480 by 9.

Going ahead to step 1:
The number 9 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 9

Going ahead to step 2:
If we divide 40 by 9, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 36 from 40, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 9

Step 3:
40 divided by 9 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtracting 36 from 40 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 9

Step 4:
9 can be fit into 44 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 444.0
Deduct 36 from 44 and we're left with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 9

Moving on to step 5:
9 goes into 88 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 4449.0
If we subtract 81 from 88, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 9

Advancing to step 6:
The number 9 fits into 70 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 44497.0
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
9 goes into 70 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 44497.7
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
70 divided by 9 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 44497.77
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 44497.77 with a remaining 0.007.
