We look at the division of 25361679 by 448 
The aim is to understand the frequency of 448 in 25361679.

Advancing to step 1:
448 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 448

Let's proceed to step 2:
25 divided by 448 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 448

Moving on to step 3:
448 can be fit into 253 0 times, resulting in a remainder of 253.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 253 leaves us with 253.
Take the next digit (6) from the dividend and append it to 253, then repeat: 2536 / 448

Going ahead to step 4:
2536 divided by 448 is 5 with a remainder of 296.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 2240 from 2536 and we're left with 296.
Append the next digit (1) from the dividend to 296 and continue with: 2961 / 448

Step 5:
The number 448 fits into 2961 6 times, leaving a remainder of 273.
The next digit of our result is 6. 
Result so far: 56.0
If we take 2688 away from 2961, we end up with 273.
Append the next digit (6) from the dividend to 273 and continue with: 2736 / 448

On to step 6:
The number 448 fits into 2736 6 times, leaving a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 566.0
If we subtract 2688 from 2736, we get 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 448

Going ahead to step 7:
When dividing 487 by 448, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 5661.0
Subtracting 448 from 487 leaves us with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 448

Going ahead to step 8:
448 can be fit into 399 0 times, resulting in a remainder of 399.
The next digit of our result is 0. 
Result so far: 56610.0
If we take 0 away from 399, we end up with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Going ahead to step 9:
If we divide 3990 by 448, we get 8 and a remainder of 406.
Record the quotient 8 as the next digit in the result. 
Result so far: 56610.8
The remainder is 406 after subtracting 3584 from 3990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 10:
If we divide 4060 by 448, we get 9 and a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 56610.89
The remainder is 28 after subtracting 4032 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
When dividing 280 by 448, we get 0 with a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 56610.89
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
448 can be fit into 2800 6 times, resulting in a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 56610.8906
Subtract 2688 from 2800 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 13:
If we divide 1120 by 448, we get 2 and a remainder of 224.
Write down 2 as next digit of the result. 
Result so far: 56610.89062
Subtract 896 from 1120 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 14:
When dividing 2240 by 448, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 56610.890625
Subtract 2240 from 2240 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 15:
448 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 56610.890625
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 16:
448 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 56610.890625
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 56610.890625, with a leftover of 0.0.
