Let's divide 624658 by 21
Our goal is to divide 624658 by 21.

Moving on to step 1:
21 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 21

Moving on to step 2:
When dividing 62 by 21, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 42 from 62 to get 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 21

On to step 3:
21 can be fit into 204 9 times, resulting in a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 189 from 204, we get 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 21

Advancing to step 4:
21 goes into 156 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 297.0
Deduct 147 from 156 and we're left with 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 21

Going ahead to step 5:
21 can be fit into 95 4 times, resulting in a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 2974.0
Subtract 84 from 95 to get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 21

Advancing to step 6:
The number 21 fits into 118 5 times, leaving a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 29745.0
The remainder is 13 after subtracting 105 from 118.
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 7:
21 goes into 130 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 29745.6
If we take 126 away from 130, we end up 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 8:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 29745.61
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.

Advancing to step 9:
190 divided by 21 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 29745.619
Subtract 189 from 190 to get 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 10:
10 divided by 21 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 29745.619
If we subtract 0 from 10, we 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.

On to step 11:
When dividing 100 by 21, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 29745.61904
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
21 goes into 160 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 29745.619047
If we take 147 away from 160, we end up 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 13:
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: 29745.6190476
Subtracting 126 from 130 leaves us 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.

Advancing to step 14:
If we divide 40 by 21, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 29745.61904761
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 29745.61904761 with a balance of 1.9e-08.
