464497 ÷ 21 
We want to figure out the number of times 464497 can be divided by 21.

Going ahead to step 1:
When dividing 4 by 21, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 21

Going ahead to step 2:
21 goes into 46 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 4 after subtracting 42 from 46.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 21

Step 3:
The number 21 fits into 44 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Deduct 42 from 44 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 21

On to step 4:
If we divide 24 by 21, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 221.0
If we take 21 away from 24, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 21

Moving on to step 5:
If we divide 39 by 21, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 2211.0
If we subtract 21 from 39, we get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 21

Moving on to step 6:
21 goes into 187 8 times with a remainder of 19.
The next digit of our result is 8. 
Result so far: 22118.0
If we take 168 away from 187, we end up 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.

Going ahead to step 7:
190 divided by 21 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 22118.9
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
The number 21 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 22118.9
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
100 divided by 21 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 22118.904
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.

Going ahead to step 10:
160 divided by 21 is 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 22118.9047
If we take 147 away from 160, we end up 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 11:
When dividing 130 by 21, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 22118.90476
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.

Step 12:
When dividing 40 by 21, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 22118.904761
If we subtract 21 from 40, we 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.

Let's proceed to step 13:
The number 21 fits into 190 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 22118.9047619
If we subtract 189 from 190, we get 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 14:
10 divided by 21 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 22118.9047619
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.

The final result is 22118.9047619 with a remainder of 1e-08.
