16645022 ÷ 494 
The aim is to understand the frequency of 494 in 16645022.

Moving on to step 1:
494 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 494

Let's proceed to step 2:
16 divided by 494 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 494

Moving on to step 3:
494 goes into 166 0 times with a remainder of 166.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 166, we get 166.
Grab the next digit (4) from the dividend, add it to 166, then carry on: 1664 / 494

Let's proceed to step 4:
494 goes into 1664 3 times with a remainder of 182.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 182 after subtracting 1482 from 1664.
Take the next digit (5) from the dividend and append it to 182, then repeat: 1825 / 494

Advancing to step 5:
When dividing 1825 by 494, we get 3 with a remainder of 343.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtracting 1482 from 1825 leaves us with 343.
Fetch the next digit (0) from the dividend, attach it to 343 and continue: 3430 / 494

Moving on to step 6:
When dividing 3430 by 494, we get 6 with a remainder of 466.
Write down 6 as next digit of the result. 
Result so far: 336.0
The remainder is 466 after subtracting 2964 from 3430.
Include the next digit (2) from the dividend after 466, then repeat: 4662 / 494

Step 7:
494 goes into 4662 9 times with a remainder of 216.
Write down 9 as next digit of the result. 
Result so far: 3369.0
Deduct 4446 from 4662 and we're left with 216.
Include the next digit (2) from the dividend after 216, then repeat: 2162 / 494

On to step 8:
2162 divided by 494 is 4 with a remainder of 186.
Write down 4 as next digit of the result. 
Result so far: 33694.0
Subtracting 1976 from 2162 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.

Moving on to step 9:
1860 divided by 494 is 3 with a remainder of 378.
Record the quotient 3 as the next digit in the result. 
Result so far: 33694.3
If we take 1482 away from 1860, we end up 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.

Moving on to step 10:
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: 33694.37
If we subtract 3458 from 3780, we get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 11:
494 can be fit into 3220 6 times, resulting in a remainder of 256.
Write down 6 as next digit of the result. 
Result so far: 33694.376
Subtracting 2964 from 3220 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 12:
When dividing 2560 by 494, we get 5 with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 33694.3765
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 13:
900 divided by 494 is 1 with a remainder of 406.
Write down 1 as next digit of the result. 
Result so far: 33694.37651
If we subtract 494 from 900, we 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.

Advancing to step 14:
When dividing 4060 by 494, we get 8 with a remainder of 108.
Put 8 as the next digit of the answer. 
Result so far: 33694.376518
Subtracting 3952 from 4060 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 15:
The number 494 fits into 1080 2 times, leaving a remainder of 92.
Use 2 as the next digit of our solution. 
Result so far: 33694.3765182
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.

Step 16:
If we divide 920 by 494, we get 1 and a remainder of 426.
Put 1 as the next digit of the answer. 
Result so far: 33694.37651821
If we take 494 away from 920, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

The final outcome is 33694.37651821, with a leftover of 4.26e-07.
