We look at the division of 30608 by 89 
We want to divide 30608 by 89.

Going ahead to step 1:
3 divided by 89 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 89

Step 2:
30 divided by 89 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 89

Moving on to step 3:
89 can be fit into 306 3 times, resulting in a remainder of 39.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 39 after subtracting 267 from 306.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 89

Step 4:
390 divided by 89 is 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtracting 356 from 390 leaves us with 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 89

On to step 5:
If we divide 348 by 89, we get 3 and a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 343.0
If we subtract 267 from 348, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 6:
89 can be fit into 810 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 343.9
Deduct 801 from 810 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
89 goes into 90 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 343.91
If we subtract 89 from 90, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
89 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 343.91
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
When dividing 100 by 89, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 343.9101
Deduct 89 from 100 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
110 divided by 89 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 343.91011
The remainder is 21 after subtracting 89 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 343.91011 with a remaining 2.1e-05.
