221601 ÷ 89 
Let's see how many times 89 fits into 221601.

On to step 1:
If we divide 2 by 89, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 89

Moving on to step 2:
89 can be fit into 22 0 times, resulting in a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 89

On to step 3:
The number 89 fits into 221 2 times, leaving a remainder of 43.
The next digit of our result is 2. 
Result so far: 2.0
If we take 178 away from 221, we end up with 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 89

Advancing to step 4:
436 divided by 89 is 4 with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we subtract 356 from 436, we get 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 89

Moving on to step 5:
89 can be fit into 800 8 times, resulting in a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 248.0
If we take 712 away from 800, we end up with 88.
Grab the next digit (1) from the dividend, add it to 88, then carry on: 881 / 89

Going ahead to step 6:
The number 89 fits into 881 9 times, leaving a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 2489.0
The remainder is 80 after subtracting 801 from 881.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 7:
89 goes into 800 8 times with a remainder of 88.
The next digit of our result is 8. 
Result so far: 2489.8
If we take 712 away from 800, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 8:
880 divided by 89 is 9 with a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 2489.89
If we take 801 away from 880, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 9:
If we divide 790 by 89, we get 8 and a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 2489.898
The remainder is 78 after subtracting 712 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 10:
When dividing 780 by 89, we get 8 with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 2489.8988
If we take 712 away from 780, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 2489.8988 with a remainder of 0.00068.
