Let's divide 624376 by 21
We want to divide 624376 by 21.

Advancing to step 1:
21 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 21

Let's proceed to step 2:
The number 21 fits into 62 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 42 from 62 leaves us with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 21

Step 3:
When dividing 204 by 21, we get 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we take 189 away from 204, we end up with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 21

Advancing to step 4:
153 divided by 21 is 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 297.0
If we take 147 away from 153, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 21

Let's proceed to step 5:
The number 21 fits into 67 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 2973.0
The remainder is 4 after subtracting 63 from 67.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 21

Going ahead to step 6:
When dividing 46 by 21, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 29732.0
Subtracting 42 from 46 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.

Going ahead to step 7:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 29732.1
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 8:
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: 29732.19
If we subtract 189 from 190, we 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.

On to step 9:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 29732.19
Subtracting 0 from 10 leaves us 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.

Advancing to step 10:
100 divided by 21 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 29732.1904
Deduct 84 from 100 and we're left 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.

Going ahead to step 11:
When dividing 160 by 21, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 29732.19047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
21 goes into 130 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 29732.190476
The remainder is 4 after subtracting 126 from 130.
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 13:
If we divide 40 by 21, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 29732.1904761
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.

On to step 14:
The number 21 fits into 190 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 29732.19047619
Deduct 189 from 190 and we're left 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.

In conclusion, the division gives 29732.19047619 with a balance of 1e-09.
