We look at the division of 21738 by 89 
Let's see how many times 89 fits into 21738.

On to step 1:
The number 89 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 89

On to step 2:
89 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 89

Advancing to step 3:
217 divided by 89 is 2 with a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 178 from 217, we get 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 89

Moving on to step 4:
393 divided by 89 is 4 with a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtracting 356 from 393 leaves us with 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 89

Advancing to step 5:
If we divide 378 by 89, we get 4 and a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 244.0
The remainder is 22 after subtracting 356 from 378.
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 6:
The number 89 fits into 220 2 times, leaving a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 244.2
Deduct 178 from 220 and we're left 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.

Let's proceed to step 7:
89 goes into 420 4 times with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 244.24
Subtracting 356 from 420 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
89 can be fit into 640 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 244.247
If we take 623 away from 640, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
170 divided by 89 is 1 with a remainder of 81.
The next digit of our result is 1. 
Result so far: 244.2471
If we subtract 89 from 170, 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 10:
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: 244.24719
If we take 801 away from 810, we end up 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.

Step 11:
If we divide 90 by 89, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 244.247191
Subtracting 89 from 90 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 12:
The number 89 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 244.247191
Deduct 0 from 10 and we're left 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.

On to step 13:
The number 89 fits into 100 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 244.24719101
The remainder is 11 after subtracting 89 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 244.24719101 with a balance of 1.1e-08.
