21422686 ÷ 689 
We're looking to find how many times 689 goes into 21422686.

Advancing to step 1:
The number 689 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
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 / 689

Going ahead to step 2:
689 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 689

On to step 3:
689 goes into 214 0 times with a remainder of 214.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 214, we get 214.
Bring next digit (2) of the dividend behind the 214 and repeat the process: 2142 / 689

Let's proceed to step 4:
The number 689 fits into 2142 3 times, leaving a remainder of 75.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 2067 from 2142 and we're left with 75.
Take the next digit (2) from the dividend and append it to 75, then repeat: 752 / 689

On to step 5:
When dividing 752 by 689, we get 1 with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 689 away from 752, we end up with 63.
Append the next digit (6) from the dividend to 63 and continue with: 636 / 689

Step 6:
When dividing 636 by 689, we get 0 with a remainder of 636.
Use 0 as the next digit of our solution. 
Result so far: 310.0
If we take 0 away from 636, we end up with 636.
Take the next digit (8) from the dividend and append it to 636, then repeat: 6368 / 689

Step 7:
689 goes into 6368 9 times with a remainder of 167.
Record the quotient 9 as the next digit in the result. 
Result so far: 3109.0
Subtracting 6201 from 6368 leaves us with 167.
Take the next digit (6) from the dividend and append it to 167, then repeat: 1676 / 689

Moving on to step 8:
If we divide 1676 by 689, we get 2 and a remainder of 298.
Use 2 as the next digit of our solution. 
Result so far: 31092.0
The remainder is 298 after subtracting 1378 from 1676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 9:
689 goes into 2980 4 times with a remainder of 224.
The next digit of our result is 4. 
Result so far: 31092.4
Subtract 2756 from 2980 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 10:
2240 divided by 689 is 3 with a remainder of 173.
Write down 3 as next digit of the result. 
Result so far: 31092.43
Subtract 2067 from 2240 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Advancing to step 11:
689 can be fit into 1730 2 times, resulting in a remainder of 352.
Use 2 as the next digit of our solution. 
Result so far: 31092.432
Subtracting 1378 from 1730 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 12:
If we divide 3520 by 689, we get 5 and a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 31092.4325
If we take 3445 away from 3520, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 13:
689 can be fit into 750 1 times, resulting in a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 31092.43251
Subtracting 689 from 750 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 14:
689 goes into 610 0 times with a remainder of 610.
Write down 0 as next digit of the result. 
Result so far: 31092.43251
If we take 0 away from 610, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 15:
689 goes into 6100 8 times with a remainder of 588.
The next digit of our result is 8. 
Result so far: 31092.4325108
Subtract 5512 from 6100 to get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Advancing to step 16:
If we divide 5880 by 689, we get 8 and a remainder of 368.
The next digit of our result is 8. 
Result so far: 31092.43251088
The remainder is 368 after subtracting 5512 from 5880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final result is 31092.43251088 with a remainder of 3.68e-07.
