We're dividing 484175 by 21 
Our goal is to divide 484175 by 21.

Advancing to step 1:
4 divided by 21 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 21

Going ahead to 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
Subtract 42 from 48 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 21

Moving on to step 3:
If we divide 64 by 21, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 23.0
Deduct 63 from 64 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 21

On to step 4:
The number 21 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
The remainder is 11 after subtracting 0 from 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 21

Going ahead to step 5:
If we divide 117 by 21, we get 5 and a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 2305.0
Subtract 105 from 117 to get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 21

Moving on to step 6:
If we divide 125 by 21, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 23055.0
If we take 105 away from 125, we end up 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 7:
If we divide 200 by 21, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 23055.9
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.

Moving on to step 8:
When dividing 110 by 21, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 23055.95
If we subtract 105 from 110, we 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.

Advancing to step 9:
If we divide 50 by 21, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 23055.952
The remainder is 8 after subtracting 42 from 50.
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 10:
If we divide 80 by 21, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 23055.9523
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.

Step 11:
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: 23055.95238
Deduct 168 from 170 and we're left 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.

Advancing to step 12:
If we divide 20 by 21, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 23055.95238
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.

On to step 13:
200 divided by 21 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 23055.9523809
Deduct 189 from 200 and we're left 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 14:
21 goes into 110 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 23055.95238095
If we subtract 105 from 110, we 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 quotient of the division is 23055.95238095, and the remainder is 5e-09.
