Let's divide 484108 by 21
We're looking to find how many times 21 goes into 484108.

Let's proceed to step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 21

Step 2:
When dividing 48 by 21, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 42 from 48, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 21

Let's proceed to step 3:
The number 21 fits into 64 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 63 from 64, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 21

Advancing to step 4:
When dividing 11 by 21, we get 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
If we subtract 0 from 11, we get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 21

Advancing to step 5:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 2305.0
If we take 105 away from 110, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 21

Let's proceed to step 6:
21 can be fit into 58 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 23052.0
If we take 42 away from 58, we end up 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.

Advancing to step 7:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 23052.7
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.

On to step 8:
If we divide 130 by 21, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 23052.76
Deduct 126 from 130 and we're left 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 9:
21 goes into 40 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 23052.761
Subtracting 21 from 40 leaves us 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 10:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 23052.7619
If we take 189 away from 190, we end up 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.

Let's proceed to step 11:
If we divide 10 by 21, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 23052.7619
The remainder is 10 after subtracting 0 from 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 12:
21 goes into 100 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 23052.761904
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.

Step 13:
21 goes into 160 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 23052.7619047
Subtract 147 from 160 to 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.

Advancing to step 14:
21 goes into 130 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 23052.76190476
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.

Our division results in 23052.76190476 with a remaining 4e-09.
