We look at the division of 698740 by 21 
Our goal is to divide 698740 by 21.

Let's proceed to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 21

Going ahead to step 2:
21 can be fit into 69 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 63 away from 69, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 21

Going ahead to step 3:
If we divide 68 by 21, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtract 63 from 68 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 21

On to step 4:
21 goes into 57 2 times with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 332.0
The remainder is 15 after subtracting 42 from 57.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 21

Moving on to step 5:
The number 21 fits into 154 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 3327.0
If we take 147 away from 154, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 21

Going ahead to step 6:
If we divide 70 by 21, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 33273.0
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 21, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 33273.3
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
21 goes into 70 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 33273.33
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 33273.33, with a leftover of 0.007.
