We look at the division of 23980219 by 455 
Let's see how many times 455 fits into 23980219.

Let's proceed to step 1:
When dividing 2 by 455, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 455

Let's proceed to step 2:
If we divide 23 by 455, we get 0 and a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 455

On to step 3:
455 goes into 239 0 times with a remainder of 239.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 239, we get 239.
Grab the next digit (8) from the dividend, add it to 239, then carry on: 2398 / 455

Moving on to step 4:
455 goes into 2398 5 times with a remainder of 123.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 2275 from 2398 leaves us with 123.
Fetch the next digit (0) from the dividend, attach it to 123 and continue: 1230 / 455

Step 5:
The number 455 fits into 1230 2 times, leaving a remainder of 320.
The next digit of our result is 2. 
Result so far: 52.0
The remainder is 320 after subtracting 910 from 1230.
Append the next digit (2) from the dividend to 320 and continue with: 3202 / 455

On to step 6:
The number 455 fits into 3202 7 times, leaving a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 527.0
Deduct 3185 from 3202 and we're left with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 455

On to step 7:
455 can be fit into 171 0 times, resulting in a remainder of 171.
The next digit of our result is 0. 
Result so far: 5270.0
Subtracting 0 from 171 leaves us with 171.
Fetch the next digit (9) from the dividend, attach it to 171 and continue: 1719 / 455

Advancing to step 8:
The number 455 fits into 1719 3 times, leaving a remainder of 354.
Record the quotient 3 as the next digit in the result. 
Result so far: 52703.0
Subtracting 1365 from 1719 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 9:
If we divide 3540 by 455, we get 7 and a remainder of 355.
The number 7 becomes the next digit in our result. 
Result so far: 52703.7
Subtract 3185 from 3540 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 10:
The number 455 fits into 3550 7 times, leaving a remainder of 365.
Write down 7 as next digit of the result. 
Result so far: 52703.77
Deduct 3185 from 3550 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Our division results in 52703.77 with a remaining 0.365.
