We divide 24940354 by 21
We want to divide 24940354 by 21.

On to step 1:
When dividing 2 by 21, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 21

Step 2:
If we divide 24 by 21, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 21 from 24 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 21

Moving on to step 3:
The number 21 fits into 39 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 11.0
If we take 21 away from 39, we end up with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 21

Step 4:
184 divided by 21 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
If we take 168 away from 184, we end up with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 21

Moving on to step 5:
When dividing 160 by 21, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 1187.0
The remainder is 13 after subtracting 147 from 160.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 21

Let's proceed to step 6:
21 can be fit into 133 6 times, resulting in a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 11876.0
If we subtract 126 from 133, we get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 21

Step 7:
21 goes into 75 3 times with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 118763.0
Subtracting 63 from 75 leaves us with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 21

Moving on to step 8:
21 can be fit into 124 5 times, resulting in a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 1187635.0
Subtract 105 from 124 to 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.

Step 9:
When dividing 190 by 21, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1187635.9
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.

Moving on to 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: 1187635.9
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.

Step 11:
When dividing 100 by 21, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1187635.904
The remainder is 16 after subtracting 84 from 100.
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 12:
If we divide 160 by 21, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 1187635.9047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 13:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1187635.90476
If we subtract 126 from 130, we get 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 14:
When dividing 40 by 21, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1187635.904761
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.

Going ahead to step 15:
When dividing 190 by 21, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1187635.9047619
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.

On to step 16:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1187635.9047619
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.

The quotient of the division is 1187635.9047619, and the remainder is 1e-08.
