We divide 688932 by 21
Let's see how many times 21 fits into 688932.

Moving on to step 1:
21 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 21

Moving on to step 2:
If we divide 68 by 21, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 63 from 68, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 21

Advancing to step 3:
When dividing 58 by 21, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtracting 42 from 58 leaves us with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 21

Going ahead to step 4:
21 can be fit into 169 8 times, resulting in a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 328.0
Deduct 168 from 169 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 21

Step 5:
The number 21 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 3280.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 21

On to step 6:
If we divide 132 by 21, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 32806.0
If we subtract 126 from 132, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
60 divided by 21 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 32806.2
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
If we divide 180 by 21, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 32806.28
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 32806.285
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
The number 21 fits into 150 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 32806.2857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
When dividing 30 by 21, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 32806.28571
Deduct 21 from 30 and we're left 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.

Advancing to step 12:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 32806.285714
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
21 goes into 60 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 32806.2857142
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
The number 21 fits into 180 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 32806.28571428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 32806.28571428, with a leftover of 1.2e-08.
