25392241 ÷ 448 
The aim is to understand the frequency of 448 in 25392241.

Moving on to step 1:
The number 448 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 448

Step 2:
448 can be fit into 25 0 times, resulting in a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 448

Advancing to step 3:
The number 448 fits into 253 0 times, leaving a remainder of 253.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 253, we end up with 253.
Include the next digit (9) from the dividend after 253, then repeat: 2539 / 448

Advancing to step 4:
If we divide 2539 by 448, we get 5 and a remainder of 299.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 2240 from 2539 leaves us with 299.
Grab the next digit (2) from the dividend, add it to 299, then carry on: 2992 / 448

Let's proceed to step 5:
The number 448 fits into 2992 6 times, leaving a remainder of 304.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we subtract 2688 from 2992, we get 304.
Grab the next digit (2) from the dividend, add it to 304, then carry on: 3042 / 448

Let's proceed to step 6:
If we divide 3042 by 448, we get 6 and a remainder of 354.
The next digit of our result is 6. 
Result so far: 566.0
If we take 2688 away from 3042, we end up with 354.
Grab the next digit (4) from the dividend, add it to 354, then carry on: 3544 / 448

Step 7:
If we divide 3544 by 448, we get 7 and a remainder of 408.
The number 7 becomes the next digit in our result. 
Result so far: 5667.0
The remainder is 408 after subtracting 3136 from 3544.
Append the next digit (1) from the dividend to 408 and continue with: 4081 / 448

Going ahead to step 8:
448 goes into 4081 9 times with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 56679.0
Deduct 4032 from 4081 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
448 goes into 490 1 times with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 56679.1
If we take 448 away from 490, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
420 divided by 448 is 0 with a remainder of 420.
The next digit of our result is 0. 
Result so far: 56679.1
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 11:
If we divide 4200 by 448, we get 9 and a remainder of 168.
Record the quotient 9 as the next digit in the result. 
Result so far: 56679.109
Subtracting 4032 from 4200 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 12:
448 can be fit into 1680 3 times, resulting in a remainder of 336.
Use 3 as the next digit of our solution. 
Result so far: 56679.1093
The remainder is 336 after subtracting 1344 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 13:
The number 448 fits into 3360 7 times, leaving a remainder of 224.
Record the quotient 7 as the next digit in the result. 
Result so far: 56679.10937
If we subtract 3136 from 3360, we 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.

Step 14:
The number 448 fits into 2240 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 56679.109375
The remainder is 0 after subtracting 2240 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 15:
If we divide 0 by 448, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 56679.109375
The remainder is 0 after subtracting 0 from 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 16:
When dividing 0 by 448, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 56679.109375
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 56679.109375, with a leftover of 0.0.
