30255 ÷ 89 
We want to figure out the number of times 30255 can be divided by 89.

On to step 1:
3 divided by 89 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 89

On to step 2:
The number 89 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 89

Advancing to step 3:
If we divide 302 by 89, we get 3 and a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 267 away from 302, we end up with 35.
Take the next digit (5) from the dividend and append it to 35, then repeat: 355 / 89

Moving on to step 4:
The number 89 fits into 355 3 times, leaving a remainder of 88.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Deduct 267 from 355 and we're left with 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 89

Step 5:
The number 89 fits into 885 9 times, leaving a remainder of 84.
Record the quotient 9 as the next digit in the result. 
Result so far: 339.0
Deduct 801 from 885 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 6:
If we divide 840 by 89, we get 9 and a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 339.9
Deduct 801 from 840 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
The number 89 fits into 390 4 times, leaving a remainder of 34.
The next digit of our result is 4. 
Result so far: 339.94
The remainder is 34 after subtracting 356 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
89 can be fit into 340 3 times, resulting in a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 339.943
Deduct 267 from 340 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 9:
89 can be fit into 730 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 339.9438
If we subtract 712 from 730, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
89 goes into 180 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 339.94382
The remainder is 2 after subtracting 178 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
89 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 339.94382
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
The number 89 fits into 200 2 times, leaving a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 339.9438202
If we subtract 178 from 200, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
89 goes into 220 2 times with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 339.94382022
Subtracting 178 from 220 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 339.94382022, with a leftover of 4.2e-08.
