Let's divide 460564 by 21
We're looking to find how many times 21 goes into 460564.

Going ahead to step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 21

Step 2:
If we divide 46 by 21, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 42 away from 46, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 21

Advancing to step 3:
40 divided by 21 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 21 from 40 to get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 21

Going ahead to step 4:
The number 21 fits into 195 9 times, leaving a remainder of 6.
The next digit of our result is 9. 
Result so far: 219.0
Subtract 189 from 195 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 21

Going ahead to step 5:
21 can be fit into 66 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 2193.0
If we subtract 63 from 66, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 21

Moving on to step 6:
If we divide 34 by 21, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 21931.0
Subtract 21 from 34 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 7:
When dividing 130 by 21, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 21931.6
If we subtract 126 from 130, we get 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 8:
When dividing 40 by 21, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 21931.61
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
21 goes into 190 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 21931.619
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.

Advancing to step 10:
10 divided by 21 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 21931.619
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
21 can be fit into 100 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 21931.61904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
160 divided by 21 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 21931.619047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 13:
21 goes into 130 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 21931.6190476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
The number 21 fits into 40 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 21931.61904761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 21931.61904761 and a remainder of 1.9e-08.
