4448491 divided by 557 
The aim is to understand the frequency of 557 in 4448491.

Let's proceed to step 1:
4 divided by 557 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 557

Moving on to step 2:
44 divided by 557 is 0 with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Bring next digit (4) of the dividend behind the 44 and repeat the process: 444 / 557

Advancing to step 3:
557 can be fit into 444 0 times, resulting in a remainder of 444.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 444, we get 444.
Take the next digit (8) from the dividend and append it to 444, then repeat: 4448 / 557

Advancing to step 4:
557 can be fit into 4448 7 times, resulting in a remainder of 549.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 549 after subtracting 3899 from 4448.
Grab the next digit (4) from the dividend, add it to 549, then carry on: 5494 / 557

Going ahead to step 5:
557 can be fit into 5494 9 times, resulting in a remainder of 481.
Write down 9 as next digit of the result. 
Result so far: 79.0
If we take 5013 away from 5494, we end up with 481.
Take the next digit (9) from the dividend and append it to 481, then repeat: 4819 / 557

Moving on to step 6:
The number 557 fits into 4819 8 times, leaving a remainder of 363.
Record the quotient 8 as the next digit in the result. 
Result so far: 798.0
Subtracting 4456 from 4819 leaves us with 363.
Include the next digit (1) from the dividend after 363, then repeat: 3631 / 557

Advancing to step 7:
557 goes into 3631 6 times with a remainder of 289.
Write down 6 as next digit of the result. 
Result so far: 7986.0
Subtract 3342 from 3631 to get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 8:
557 goes into 2890 5 times with a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 7986.5
The remainder is 105 after subtracting 2785 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 9:
557 can be fit into 1050 1 times, resulting in a remainder of 493.
Put 1 as the next digit of the answer. 
Result so far: 7986.51
Deduct 557 from 1050 and we're left with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Going ahead to step 10:
4930 divided by 557 is 8 with a remainder of 474.
Put 8 as the next digit of the answer. 
Result so far: 7986.518
Deduct 4456 from 4930 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Advancing to step 11:
4740 divided by 557 is 8 with a remainder of 284.
Record the quotient 8 as the next digit in the result. 
Result so far: 7986.5188
If we subtract 4456 from 4740, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

After the division, we end up with 7986.5188 and a remainder of 0.00284.
