We're dividing 55992474 by 448 
The aim is to understand the frequency of 448 in 55992474.

Moving on to step 1:
The number 448 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 448

Going ahead to step 2:
448 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 448

Step 3:
When dividing 559 by 448, we get 1 with a remainder of 111.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 448 from 559 to get 111.
Append the next digit (9) from the dividend to 111 and continue with: 1119 / 448

Advancing to step 4:
448 goes into 1119 2 times with a remainder of 223.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 223 after subtracting 896 from 1119.
Grab the next digit (2) from the dividend, add it to 223, then carry on: 2232 / 448

Step 5:
If we divide 2232 by 448, we get 4 and a remainder of 440.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we subtract 1792 from 2232, we get 440.
Fetch the next digit (4) from the dividend, attach it to 440 and continue: 4404 / 448

Advancing to step 6:
If we divide 4404 by 448, we get 9 and a remainder of 372.
The number 9 becomes the next digit in our result. 
Result so far: 1249.0
If we subtract 4032 from 4404, we get 372.
Include the next digit (7) from the dividend after 372, then repeat: 3727 / 448

Advancing to step 7:
448 can be fit into 3727 8 times, resulting in a remainder of 143.
Use 8 as the next digit of our solution. 
Result so far: 12498.0
Deduct 3584 from 3727 and we're left with 143.
Bring next digit (4) of the dividend behind the 143 and repeat the process: 1434 / 448

On to step 8:
1434 divided by 448 is 3 with a remainder of 90.
The number 3 becomes the next digit in our result. 
Result so far: 124983.0
If we take 1344 away from 1434, we end up 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.

Going ahead to step 9:
When dividing 900 by 448, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 124983.2
Deduct 896 from 900 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
448 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 124983.2
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
448 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 124983.2
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 124983.2, with a leftover of 0.04.
