We look at the division of 624205 by 21 
Our goal is to divide 624205 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
Subtract 0 from 6 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 21

Going ahead to step 2:
When dividing 62 by 21, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 42 from 62 leaves us with 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 21

Moving on to step 3:
21 can be fit into 204 9 times, resulting in a remainder of 15.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 189 from 204 to get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 21

Step 4:
When dividing 152 by 21, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 297.0
Subtract 147 from 152 to get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 21

Moving on to step 5:
When dividing 50 by 21, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2972.0
Subtracting 42 from 50 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 21

Step 6:
If we divide 85 by 21, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 29724.0
If we take 84 away from 85, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 21, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 29724.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 29724.04
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
21 goes into 160 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 29724.047
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
When dividing 130 by 21, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 29724.0476
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 29724.04761
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 12:
If we divide 190 by 21, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 29724.047619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
When dividing 10 by 21, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 29724.047619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
If we divide 100 by 21, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 29724.04761904
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 29724.04761904 with a balance of 1.6e-08.
