21406 divided by 89 
We're looking to find how many times 89 goes into 21406.

Moving on to step 1:
If we divide 2 by 89, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 89

Moving on to step 2:
89 can be fit into 21 0 times, resulting in 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 (4) from the dividend, add it to 21, then carry on: 214 / 89

Advancing to step 3:
The number 89 fits into 214 2 times, leaving a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 178 away from 214, we end up with 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 89

Step 4:
If we divide 360 by 89, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 24.0
The remainder is 4 after subtracting 356 from 360.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 89

On to step 5:
The number 89 fits into 46 0 times, leaving a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 240.0
Subtract 0 from 46 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 6:
The number 89 fits into 460 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 240.5
The remainder is 15 after subtracting 445 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
When dividing 150 by 89, we get 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 240.51
Subtract 89 from 150 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 8:
The number 89 fits into 610 6 times, leaving a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 240.516
Deduct 534 from 610 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 9:
If we divide 760 by 89, we get 8 and a remainder of 48.
The next digit of our result is 8. 
Result so far: 240.5168
Subtracting 712 from 760 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
480 divided by 89 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 240.51685
Subtract 445 from 480 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 11:
350 divided by 89 is 3 with a remainder of 83.
The next digit of our result is 3. 
Result so far: 240.516853
Deduct 267 from 350 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 12:
When dividing 830 by 89, we get 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 240.5168539
Subtract 801 from 830 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 13:
The number 89 fits into 290 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 240.51685393
Subtract 267 from 290 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 240.51685393 with a remainder of 2.3e-08.
