20494893 ÷ 494 
The aim is to understand the frequency of 494 in 20494893.

Let's proceed to step 1:
494 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 494

Moving on to step 2:
494 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 494

Step 3:
If we divide 204 by 494, we get 0 and a remainder of 204.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 204 to get 204.
Include the next digit (9) from the dividend after 204, then repeat: 2049 / 494

Going ahead to step 4:
If we divide 2049 by 494, we get 4 and a remainder of 73.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 73 after subtracting 1976 from 2049.
Include the next digit (4) from the dividend after 73, then repeat: 734 / 494

On to step 5:
734 divided by 494 is 1 with a remainder of 240.
The next digit of our result is 1. 
Result so far: 41.0
If we take 494 away from 734, we end up with 240.
Include the next digit (8) from the dividend after 240, then repeat: 2408 / 494

Going ahead to step 6:
When dividing 2408 by 494, we get 4 with a remainder of 432.
Use 4 as the next digit of our solution. 
Result so far: 414.0
The remainder is 432 after subtracting 1976 from 2408.
Take the next digit (9) from the dividend and append it to 432, then repeat: 4329 / 494

Moving on to step 7:
494 can be fit into 4329 8 times, resulting in a remainder of 377.
Record the quotient 8 as the next digit in the result. 
Result so far: 4148.0
If we take 3952 away from 4329, we end up with 377.
Take the next digit (3) from the dividend and append it to 377, then repeat: 3773 / 494

Moving on to step 8:
When dividing 3773 by 494, we get 7 with a remainder of 315.
The next digit of our result is 7. 
Result so far: 41487.0
If we take 3458 away from 3773, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 9:
494 can be fit into 3150 6 times, resulting in a remainder of 186.
The next digit of our result is 6. 
Result so far: 41487.6
Subtracting 2964 from 3150 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 10:
When dividing 1860 by 494, we get 3 with a remainder of 378.
The number 3 becomes the next digit in our result. 
Result so far: 41487.63
Deduct 1482 from 1860 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 11:
494 can be fit into 3780 7 times, resulting in a remainder of 322.
Write down 7 as next digit of the result. 
Result so far: 41487.637
Subtracting 3458 from 3780 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 12:
3220 divided by 494 is 6 with a remainder of 256.
The next digit of our result is 6. 
Result so far: 41487.6376
Subtract 2964 from 3220 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 13:
494 goes into 2560 5 times with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 41487.63765
Subtracting 2470 from 2560 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 14:
The number 494 fits into 900 1 times, leaving a remainder of 406.
Record the quotient 1 as the next digit in the result. 
Result so far: 41487.637651
Subtract 494 from 900 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

On to step 15:
494 goes into 4060 8 times with a remainder of 108.
Use 8 as the next digit of our solution. 
Result so far: 41487.6376518
The remainder is 108 after subtracting 3952 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 16:
When dividing 1080 by 494, we get 2 with a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 41487.63765182
If we subtract 988 from 1080, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final outcome is 41487.63765182, with a leftover of 9.2e-08.
