297185 ÷ 21 
We want to figure out the number of times 297185 can be divided by 21.

Moving on to step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 21

Going ahead to step 2:
When dividing 29 by 21, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we take 21 away from 29, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 21

Let's proceed to step 3:
If we divide 87 by 21, we get 4 and a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 84 from 87 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 21

On to step 4:
When dividing 31 by 21, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 141.0
The remainder is 10 after subtracting 21 from 31.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 21

Going ahead to step 5:
If we divide 108 by 21, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 1415.0
If we subtract 105 from 108, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 21

Going ahead to step 6:
35 divided by 21 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 14151.0
If we take 21 away from 35, 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.

Going ahead to step 7:
140 divided by 21 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 14151.6
Subtract 126 from 140 to 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.

On to step 8:
140 divided by 21 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 14151.66
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 14151.66, with a leftover of 0.014.
