697172 ÷ 21 
Let's see how many times 21 fits into 697172.

Moving on to step 1:
When dividing 6 by 21, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 21

Advancing to step 2:
When dividing 69 by 21, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 63 from 69 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 21

Going ahead to step 3:
21 goes into 67 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Deduct 63 from 67 and we're left with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 21

Moving on to step 4:
When dividing 41 by 21, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 331.0
The remainder is 20 after subtracting 21 from 41.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 21

Going ahead to step 5:
When dividing 207 by 21, we get 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 3319.0
If we subtract 189 from 207, we get 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 21

On to step 6:
When dividing 182 by 21, we get 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 33198.0
If we take 168 away from 182, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
21 can be fit into 140 6 times, resulting in a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 33198.6
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
21 goes into 140 6 times with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 33198.66
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 33198.66, with a leftover of 0.014.
