Let's divide 623224 by 21
We want to divide 623224 by 21.

Step 1:
21 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 21

On to step 2:
21 can be fit into 62 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 42 away from 62, we end up with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 21

Step 3:
If we divide 203 by 21, we get 9 and a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 29.0
The remainder is 14 after subtracting 189 from 203.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 21

Moving on to step 4:
21 goes into 142 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 296.0
Subtracting 126 from 142 leaves us with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 21

Moving on to step 5:
The number 21 fits into 162 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 2967.0
The remainder is 15 after subtracting 147 from 162.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 21

Going ahead to step 6:
154 divided by 21 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 29677.0
Deduct 147 from 154 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.

Going ahead to step 7:
When dividing 70 by 21, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 29677.3
Subtracting 63 from 70 leaves us 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.

Moving on to step 8:
70 divided by 21 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 29677.33
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.

In conclusion, the division gives 29677.33 with a balance of 0.007.
