501425 divided by 21 
Our goal is to divide 501425 by 21.

Let's proceed to step 1:
21 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 21

Step 2:
When dividing 50 by 21, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 42 from 50 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 21

Going ahead to step 3:
21 can be fit into 81 3 times, resulting in a remainder of 18.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 63 from 81 to get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 21

Advancing to step 4:
When dividing 184 by 21, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 238.0
Subtract 168 from 184 to get 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 21

Going ahead to step 5:
21 goes into 162 7 times with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 2387.0
If we subtract 147 from 162, we get 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 21

Going ahead to step 6:
When dividing 155 by 21, we get 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 23877.0
If we subtract 147 from 155, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 23877.3
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
If we divide 170 by 21, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 23877.38
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 23877.38
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
When dividing 200 by 21, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 23877.3809
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 11:
When dividing 110 by 21, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 23877.38095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
21 goes into 50 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 23877.380952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
When dividing 80 by 21, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 23877.3809523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
If we divide 170 by 21, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 23877.38095238
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 23877.38095238 with a remainder of 2e-09.
