305521 ÷ 89 
Our goal is to divide 305521 by 89.

Let's proceed to step 1:
When dividing 3 by 89, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 89

Moving on to step 2:
89 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 89

Advancing to step 3:
89 can be fit into 305 3 times, resulting in a remainder of 38.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 267 from 305 to get 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 89

On to step 4:
89 can be fit into 385 4 times, resulting in a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
The remainder is 29 after subtracting 356 from 385.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 89

Let's proceed to step 5:
If we divide 292 by 89, we get 3 and a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 343.0
If we subtract 267 from 292, we get 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 89

Advancing to step 6:
89 can be fit into 251 2 times, resulting in a remainder of 73.
Record the quotient 2 as the next digit in the result. 
Result so far: 3432.0
Deduct 178 from 251 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.

Moving on to step 7:
When dividing 730 by 89, we get 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 3432.8
If we take 712 away from 730, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
89 can be fit into 180 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 3432.82
Subtracting 178 from 180 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
20 divided by 89 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3432.82
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
89 goes into 200 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 3432.8202
If we take 178 away from 200, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
220 divided by 89 is 2 with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 3432.82022
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 result is 3432.82022 with a remainder of 4.2e-05.
