21635 divided by 89 
Our goal is to divide 21635 by 89.

Let's proceed to step 1:
When dividing 2 by 89, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 89

Going ahead to step 2:
If we divide 21 by 89, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 89

On to step 3:
89 goes into 216 2 times with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 38 after subtracting 178 from 216.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 89

On to step 4:
When dividing 383 by 89, we get 4 with a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 356 away from 383, we end up with 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 89

Step 5:
The number 89 fits into 275 3 times, leaving a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 243.0
Subtract 267 from 275 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 6:
89 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 243.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 7:
800 divided by 89 is 8 with a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 243.08
The remainder is 88 after subtracting 712 from 800.
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:
If we divide 880 by 89, we get 9 and a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 243.089
Subtract 801 from 880 to get 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:
The number 89 fits into 790 8 times, leaving a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 243.0898
If we subtract 712 from 790, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 10:
89 goes into 780 8 times with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 243.08988
Subtract 712 from 780 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 243.08988 with a balance of 6.8e-05.
