456692 ÷ 21 
We're looking to find how many times 21 goes into 456692.

Let's proceed to step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 21

On to step 2:
If we divide 45 by 21, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 42 from 45 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 21

On to step 3:
36 divided by 21 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 15 after subtracting 21 from 36.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 21

On to step 4:
21 can be fit into 156 7 times, resulting in a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 217.0
Deduct 147 from 156 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 21

Advancing to step 5:
21 can be fit into 99 4 times, resulting in a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 2174.0
If we subtract 84 from 99, we get 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 21

Let's proceed to step 6:
21 goes into 152 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 21747.0
If we take 147 away from 152, we end up 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.

On to step 7:
If we divide 50 by 21, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 21747.2
Subtracting 42 from 50 leaves us with 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 8:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 21747.23
If we subtract 63 from 80, we 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.

On to step 9:
21 goes into 170 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 21747.238
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.

Let's proceed to step 10:
21 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 21747.238
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.

Going ahead to step 11:
If we divide 200 by 21, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 21747.23809
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 12:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 21747.238095
If we take 105 away from 110, we end up 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.

On to step 13:
50 divided by 21 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 21747.2380952
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 21747.23809523
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.

The final outcome is 21747.23809523, with a leftover of 1.7e-08.
