484217 divided by 21 
We want to figure out the number of times 484217 can be divided by 21.

Moving on to step 1:
21 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 21

Step 2:
48 divided by 21 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 42 from 48, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 21

On to step 3:
64 divided by 21 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 63 from 64 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 21

Step 4:
If we divide 12 by 21, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
Subtract 0 from 12 to get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 21

Going ahead to step 5:
121 divided by 21 is 5 with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 2305.0
Subtract 105 from 121 to get 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 21

Moving on to step 6:
When dividing 167 by 21, we get 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 23057.0
The remainder is 20 after subtracting 147 from 167.
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 7:
When dividing 200 by 21, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 23057.9
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 23057.95
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
If we divide 50 by 21, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 23057.952
If we subtract 42 from 50, 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.

Step 10:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 23057.9523
Subtracting 63 from 80 leaves us 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.

Going ahead to step 11:
If we divide 170 by 21, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 23057.95238
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.

Moving on to step 12:
21 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 23057.95238
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
200 divided by 21 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 23057.9523809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
21 goes into 110 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 23057.95238095
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.

The final result is 23057.95238095 with a remainder of 5e-09.
