16494316 divided by 557 
The aim is to understand the frequency of 557 in 16494316.

Moving on to step 1:
When dividing 1 by 557, we get 0 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.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 557

Going ahead to step 2:
The number 557 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 557

Moving on to step 3:
164 divided by 557 is 0 with a remainder of 164.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 164, we get 164.
Fetch the next digit (9) from the dividend, attach it to 164 and continue: 1649 / 557

On to step 4:
557 goes into 1649 2 times with a remainder of 535.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1114 from 1649, we get 535.
Bring next digit (4) of the dividend behind the 535 and repeat the process: 5354 / 557

Step 5:
If we divide 5354 by 557, we get 9 and a remainder of 341.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Deduct 5013 from 5354 and we're left with 341.
Bring next digit (3) of the dividend behind the 341 and repeat the process: 3413 / 557

Step 6:
When dividing 3413 by 557, we get 6 with a remainder of 71.
The number 6 becomes the next digit in our result. 
Result so far: 296.0
The remainder is 71 after subtracting 3342 from 3413.
Bring next digit (1) of the dividend behind the 71 and repeat the process: 711 / 557

Moving on to step 7:
When dividing 711 by 557, we get 1 with a remainder of 154.
Record the quotient 1 as the next digit in the result. 
Result so far: 2961.0
Deduct 557 from 711 and we're left with 154.
Grab the next digit (6) from the dividend, add it to 154, then carry on: 1546 / 557

Moving on to step 8:
557 can be fit into 1546 2 times, resulting in a remainder of 432.
The next digit of our result is 2. 
Result so far: 29612.0
Deduct 1114 from 1546 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 9:
557 goes into 4320 7 times with a remainder of 421.
The next digit of our result is 7. 
Result so far: 29612.7
Subtract 3899 from 4320 to get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Let's proceed to step 10:
4210 divided by 557 is 7 with a remainder of 311.
The next digit of our result is 7. 
Result so far: 29612.77
Subtracting 3899 from 4210 leaves us with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

The final outcome is 29612.77, with a leftover of 0.311.
