We divide 212124 by 9
Let's see how many times 9 fits into 212124.

Moving on to step 1:
The number 9 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 9

Going ahead to step 2:
9 can be fit into 21 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 18 from 21 and we're left with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 9

Advancing to step 3:
If we divide 32 by 9, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 5 after subtracting 27 from 32.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 9

On to step 4:
When dividing 51 by 9, we get 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 235.0
The remainder is 6 after subtracting 45 from 51.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 9

Let's proceed to step 5:
The number 9 fits into 62 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 2356.0
Subtract 54 from 62 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 9

Step 6:
The number 9 fits into 84 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 23569.0
If we take 81 away from 84, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
If we divide 30 by 9, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 23569.3
Deduct 27 from 30 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
When dividing 30 by 9, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 23569.33
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 23569.33, and the remainder is 0.003.
