We look at the division of 198668 by 720 
We want to figure out the number of times 198668 can be divided by 720.

Let's proceed to step 1:
720 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 720

Advancing to step 2:
19 divided by 720 is 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 720

Moving on to step 3:
720 can be fit into 198 0 times, resulting in a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 198 leaves us with 198.
Grab the next digit (6) from the dividend, add it to 198, then carry on: 1986 / 720

Let's proceed to step 4:
When dividing 1986 by 720, we get 2 with a remainder of 546.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1440 from 1986 to get 546.
Take the next digit (6) from the dividend and append it to 546, then repeat: 5466 / 720

Step 5:
If we divide 5466 by 720, we get 7 and a remainder of 426.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we take 5040 away from 5466, we end up with 426.
Take the next digit (8) from the dividend and append it to 426, then repeat: 4268 / 720

Going ahead to step 6:
If we divide 4268 by 720, we get 5 and a remainder of 668.
The next digit of our result is 5. 
Result so far: 275.0
If we subtract 3600 from 4268, we get 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Going ahead to step 7:
When dividing 6680 by 720, we get 9 with a remainder of 200.
The next digit of our result is 9. 
Result so far: 275.9
Deduct 6480 from 6680 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 8:
720 can be fit into 2000 2 times, resulting in a remainder of 560.
Record the quotient 2 as the next digit in the result. 
Result so far: 275.92
If we take 1440 away from 2000, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 9:
720 can be fit into 5600 7 times, resulting in a remainder of 560.
The number 7 becomes the next digit in our result. 
Result so far: 275.927
Deduct 5040 from 5600 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 10:
The number 720 fits into 5600 7 times, leaving a remainder of 560.
The next digit of our result is 7. 
Result so far: 275.9277
If we take 5040 away from 5600, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final result is 275.9277 with a remainder of 0.0056.
