We look at the division of 30550 by 45 
Our goal is to divide 30550 by 45.

Step 1:
When dividing 3 by 45, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 45

On to step 2:
When dividing 30 by 45, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 45

Advancing to step 3:
305 divided by 45 is 6 with a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 270 from 305 to get 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 45

Advancing to step 4:
If we divide 355 by 45, we get 7 and a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Deduct 315 from 355 and we're left with 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 45

Moving on to step 5:
45 can be fit into 400 8 times, resulting in a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 678.0
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 6:
45 can be fit into 400 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 678.8
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
400 divided by 45 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 678.88
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 678.88 and a remainder of 0.04.
