We're dividing 44570394 by 557 
The aim is to understand the frequency of 557 in 44570394.

On to step 1:
The number 557 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 557

Moving on to step 2:
557 can be fit into 44 0 times, resulting in a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 557

Let's proceed to step 3:
The number 557 fits into 445 0 times, leaving a remainder of 445.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 445 leaves us with 445.
Bring next digit (7) of the dividend behind the 445 and repeat the process: 4457 / 557

Advancing to step 4:
The number 557 fits into 4457 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 4456 from 4457 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 557

Moving on to step 5:
10 divided by 557 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 80.0
If we subtract 0 from 10, we get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 557

On to step 6:
The number 557 fits into 103 0 times, leaving a remainder of 103.
The number 0 becomes the next digit in our result. 
Result so far: 800.0
Subtract 0 from 103 to get 103.
Grab the next digit (9) from the dividend, add it to 103, then carry on: 1039 / 557

Advancing to step 7:
1039 divided by 557 is 1 with a remainder of 482.
Record the quotient 1 as the next digit in the result. 
Result so far: 8001.0
If we subtract 557 from 1039, we get 482.
Grab the next digit (4) from the dividend, add it to 482, then carry on: 4824 / 557

Moving on to step 8:
557 can be fit into 4824 8 times, resulting in a remainder of 368.
Record the quotient 8 as the next digit in the result. 
Result so far: 80018.0
The remainder is 368 after subtracting 4456 from 4824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 9:
The number 557 fits into 3680 6 times, leaving a remainder of 338.
The number 6 becomes the next digit in our result. 
Result so far: 80018.6
The remainder is 338 after subtracting 3342 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 10:
557 can be fit into 3380 6 times, resulting in a remainder of 38.
The next digit of our result is 6. 
Result so far: 80018.66
Subtract 3342 from 3380 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 80018.66 and a remainder of 0.038.
