We're dividing 687097 by 21 
Let's see how many times 21 fits into 687097.

Step 1:
When dividing 6 by 21, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 21

Step 2:
When dividing 68 by 21, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 63 from 68 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 21

Moving on to step 3:
21 can be fit into 57 2 times, resulting in a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtract 42 from 57 to get 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 21

Moving on to step 4:
21 goes into 150 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 327.0
If we take 147 away from 150, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 21

On to step 5:
21 can be fit into 39 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 3271.0
If we subtract 21 from 39, we get 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 21

Step 6:
When dividing 187 by 21, we get 8 with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 32718.0
Subtracting 168 from 187 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 32718.9
The remainder is 1 after subtracting 189 from 190.
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 8:
If we divide 10 by 21, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 32718.9
If we subtract 0 from 10, we 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.

Going ahead to step 9:
21 goes into 100 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 32718.904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
If we divide 160 by 21, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 32718.9047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
130 divided by 21 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 32718.90476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
40 divided by 21 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 32718.904761
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
The number 21 fits into 190 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 32718.9047619
If we take 189 away from 190, we end up 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.

Advancing to step 14:
When dividing 10 by 21, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 32718.9047619
Subtracting 0 from 10 leaves us 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.

The final outcome is 32718.9047619, with a leftover of 1e-08.
