494677 divided by 21 
We want to figure out the number of times 494677 can be divided by 21.

Let's proceed to step 1:
21 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 21

Advancing to step 2:
When dividing 49 by 21, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 42 from 49 leaves us with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 21

Advancing to step 3:
The number 21 fits into 74 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 63 from 74 to get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 21

Advancing to step 4:
If we divide 116 by 21, we get 5 and a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 235.0
Deduct 105 from 116 and we're left with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 21

Going ahead to step 5:
21 goes into 117 5 times with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 2355.0
Deduct 105 from 117 and we're left with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 21

Moving on to step 6:
127 divided by 21 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 23556.0
If we subtract 126 from 127, 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 7:
21 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 23556.0
Subtracting 0 from 10 leaves us 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.

On to step 8:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 23556.04
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
21 goes into 160 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 23556.047
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.

On to step 10:
If we divide 130 by 21, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 23556.0476
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 23556.04761
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.

Moving on to step 12:
190 divided by 21 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 23556.047619
The remainder is 1 after subtracting 189 from 190.
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 13:
10 divided by 21 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 23556.047619
Deduct 0 from 10 and we're left 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.

Moving on to step 14:
21 goes into 100 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 23556.04761904
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.

The quotient of the division is 23556.04761904, and the remainder is 1.6e-08.
