Let's divide 470234 by 21
Let's see how many times 21 fits into 470234.

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
Deduct 0 from 4 and we're left with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 21

Step 2:
21 goes into 47 2 times with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 5 after subtracting 42 from 47.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 21

Moving on to step 3:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 42 from 50, we get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 21

Going ahead to step 4:
82 divided by 21 is 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 223.0
If we take 63 away from 82, we end up with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 21

On to step 5:
When dividing 193 by 21, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 2239.0
If we take 189 away from 193, we end up with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 21

Going ahead to step 6:
44 divided by 21 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 22392.0
If we take 42 away from 44, 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 7:
21 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 22392.0
If we take 0 away from 20, 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.

Let's proceed to step 8:
If we divide 200 by 21, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 22392.09
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 9:
110 divided by 21 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 22392.095
Deduct 105 from 110 and we're left 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.

Advancing to step 10:
If we divide 50 by 21, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 22392.0952
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.

Advancing to step 11:
21 goes into 80 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 22392.09523
Deduct 63 from 80 and we're left 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 12:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 22392.095238
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.

Advancing to step 13:
20 divided by 21 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 22392.095238
If we take 0 away from 20, 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 14:
21 goes into 200 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 22392.09523809
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.

After the division, we end up with 22392.09523809 and a remainder of 1.1e-08.
