We look at the division of 30735580 by 720 
We want to divide 30735580 by 720.

Going ahead to step 1:
The number 720 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 720

On to step 2:
30 divided by 720 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 720

Step 3:
720 can be fit into 307 0 times, resulting in a remainder of 307.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 307, we end up with 307.
Include the next digit (3) from the dividend after 307, then repeat: 3073 / 720

Advancing to step 4:
If we divide 3073 by 720, we get 4 and a remainder of 193.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 2880 from 3073 and we're left with 193.
Take the next digit (5) from the dividend and append it to 193, then repeat: 1935 / 720

Step 5:
The number 720 fits into 1935 2 times, leaving a remainder of 495.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 1440 from 1935 to get 495.
Bring next digit (5) of the dividend behind the 495 and repeat the process: 4955 / 720

Advancing to step 6:
If we divide 4955 by 720, we get 6 and a remainder of 635.
Write down 6 as next digit of the result. 
Result so far: 426.0
Subtract 4320 from 4955 to get 635.
Fetch the next digit (8) from the dividend, attach it to 635 and continue: 6358 / 720

Let's proceed to step 7:
720 goes into 6358 8 times with a remainder of 598.
Put 8 as the next digit of the answer. 
Result so far: 4268.0
Subtract 5760 from 6358 to get 598.
Fetch the next digit (0) from the dividend, attach it to 598 and continue: 5980 / 720

On to step 8:
The number 720 fits into 5980 8 times, leaving a remainder of 220.
Use 8 as the next digit of our solution. 
Result so far: 42688.0
The remainder is 220 after subtracting 5760 from 5980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 9:
720 goes into 2200 3 times with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 42688.3
The remainder is 40 after subtracting 2160 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 720 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 42688.3
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 11:
4000 divided by 720 is 5 with a remainder of 400.
The number 5 becomes the next digit in our result. 
Result so far: 42688.305
The remainder is 400 after subtracting 3600 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 12:
If we divide 4000 by 720, we get 5 and a remainder of 400.
The next digit of our result is 5. 
Result so far: 42688.3055
Subtract 3600 from 4000 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 42688.3055 and a remainder of 0.004.
