We look at the division of 690867 by 21 
We want to figure out the number of times 690867 can be divided by 21.

Moving on to step 1:
When dividing 6 by 21, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 21

On to step 2:
69 divided by 21 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 63 from 69 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 21

Step 3:
21 goes into 60 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtract 42 from 60 to get 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 21

On to step 4:
188 divided by 21 is 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 328.0
If we take 168 away from 188, we end up with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 21

Going ahead to step 5:
21 can be fit into 206 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 3289.0
Subtracting 189 from 206 leaves us with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 21

Going ahead to step 6:
If we divide 177 by 21, we get 8 and a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 32898.0
Subtracting 168 from 177 leaves us 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.

Step 7:
If we divide 90 by 21, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 32898.4
If we subtract 84 from 90, 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.

Advancing to step 8:
When dividing 60 by 21, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 32898.42
If we subtract 42 from 60, we 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.

Moving on to step 9:
180 divided by 21 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 32898.428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
21 goes into 120 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 32898.4285
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.

Going ahead to step 11:
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: 32898.42857
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
When dividing 30 by 21, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 32898.428571
The remainder is 9 after subtracting 21 from 30.
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 13:
21 goes into 90 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 32898.4285714
Subtract 84 from 90 to 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.

On to step 14:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 32898.42857142
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.

The quotient of the division is 32898.42857142, and the remainder is 1.8e-08.
