7208875 ÷ 448 
The aim is to understand the frequency of 448 in 7208875.

Moving on to step 1:
7 divided by 448 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 448

Let's proceed to step 2:
When dividing 72 by 448, we get 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 448

On to step 3:
The number 448 fits into 720 1 times, leaving a remainder of 272.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 448 from 720 and we're left with 272.
Bring next digit (8) of the dividend behind the 272 and repeat the process: 2728 / 448

Step 4:
448 goes into 2728 6 times with a remainder of 40.
The next digit of our result is 6. 
Result so far: 16.0
If we take 2688 away from 2728, we end up with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 448

Advancing to step 5:
448 can be fit into 408 0 times, resulting in a remainder of 408.
Put 0 as the next digit of the answer. 
Result so far: 160.0
The remainder is 408 after subtracting 0 from 408.
Include the next digit (7) from the dividend after 408, then repeat: 4087 / 448

Let's proceed to step 6:
If we divide 4087 by 448, we get 9 and a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 1609.0
Subtract 4032 from 4087 to get 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 448

Step 7:
448 can be fit into 555 1 times, resulting in a remainder of 107.
Use 1 as the next digit of our solution. 
Result so far: 16091.0
If we subtract 448 from 555, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 8:
When dividing 1070 by 448, we get 2 with a remainder of 174.
Use 2 as the next digit of our solution. 
Result so far: 16091.2
Subtracting 896 from 1070 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 9:
448 goes into 1740 3 times with a remainder of 396.
Write down 3 as next digit of the result. 
Result so far: 16091.23
If we subtract 1344 from 1740, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 10:
3960 divided by 448 is 8 with a remainder of 376.
Record the quotient 8 as the next digit in the result. 
Result so far: 16091.238
If we take 3584 away from 3960, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 11:
The number 448 fits into 3760 8 times, leaving a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 16091.2388
If we take 3584 away from 3760, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final outcome is 16091.2388, with a leftover of 0.00176.
