We divide 209815 by 9
Our goal is to divide 209815 by 9.

Advancing to step 1:
When dividing 2 by 9, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 9

On to step 2:
9 goes into 20 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 18 from 20 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 9

Advancing to step 3:
If we divide 29 by 9, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 27 from 29 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 9

Going ahead to step 4:
When dividing 28 by 9, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 233.0
The remainder is 1 after subtracting 27 from 28.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 9

Moving on to step 5:
If we divide 11 by 9, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 2331.0
Deduct 9 from 11 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 9

Let's proceed to step 6:
25 divided by 9 is 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 23312.0
The remainder is 7 after subtracting 18 from 25.
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 7:
The number 9 fits into 70 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 23312.7
If we subtract 63 from 70, we 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.

Going ahead to step 8:
When dividing 70 by 9, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 23312.77
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.

The final outcome is 23312.77, with a leftover of 0.007.
