We look at the division of 21855260 by 89 
We want to figure out the number of times 21855260 can be divided by 89.

Let's proceed to step 1:
89 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in 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:
21 divided by 89 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 89

Step 3:
89 can be fit into 218 2 times, resulting in a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 178 from 218 leaves us with 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 89

Advancing to step 4:
When dividing 405 by 89, we get 4 with a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 49 after subtracting 356 from 405.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 89

Step 5:
495 divided by 89 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 245.0
If we subtract 445 from 495, we get 50.
Include the next digit (2) from the dividend after 50, then repeat: 502 / 89

Advancing to step 6:
The number 89 fits into 502 5 times, leaving a remainder of 57.
The next digit of our result is 5. 
Result so far: 2455.0
The remainder is 57 after subtracting 445 from 502.
Bring next digit (6) of the dividend behind the 57 and repeat the process: 576 / 89

Advancing to step 7:
When dividing 576 by 89, we get 6 with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 24556.0
Subtract 534 from 576 to get 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 89

Moving on to step 8:
89 can be fit into 420 4 times, resulting in a remainder of 64.
The next digit of our result is 4. 
Result so far: 245564.0
Deduct 356 from 420 and we're left 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.

Advancing to step 9:
89 goes into 640 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 245564.7
If we subtract 623 from 640, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
The number 89 fits into 170 1 times, leaving a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 245564.71
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 11:
89 goes into 810 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 245564.719
If we subtract 801 from 810, we get 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 12:
The number 89 fits into 90 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 245564.7191
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.

Going ahead to step 13:
The number 89 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 245564.7191
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
89 can be fit into 100 1 times, resulting in a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 245564.719101
If we subtract 89 from 100, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 15:
89 goes into 110 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 245564.7191011
Subtracting 89 from 110 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 245564.7191011 with a remainder of 2.1e-07.
