Let's divide 210861 by 9
Let's see how many times 9 fits into 210861.

Moving on to step 1:
9 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 9

Let's proceed to step 2:
9 goes into 21 2 times with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 18 from 21 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 9

Advancing to step 3:
9 goes into 30 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we take 27 away from 30, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 9

Moving on to step 4:
38 divided by 9 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 234.0
If we take 36 away from 38, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 9

Going ahead to step 5:
9 can be fit into 26 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2342.0
The remainder is 8 after subtracting 18 from 26.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 9

Moving on to step 6:
If we divide 81 by 9, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 23429.0
If we take 81 away from 81, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
0 divided by 9 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23429.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 9, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 23429.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 23429.0 with a remaining 0.0.
