6112721 ÷ 448 
The aim is to understand the frequency of 448 in 6112721.

Advancing to step 1:
If we divide 6 by 448, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 448

Advancing to step 2:
The number 448 fits into 61 0 times, leaving a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 448

Moving on to step 3:
If we divide 611 by 448, we get 1 and a remainder of 163.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 448 from 611 to get 163.
Include the next digit (2) from the dividend after 163, then repeat: 1632 / 448

On to step 4:
If we divide 1632 by 448, we get 3 and a remainder of 288.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1344 from 1632 and we're left with 288.
Append the next digit (7) from the dividend to 288 and continue with: 2887 / 448

Let's proceed to step 5:
When dividing 2887 by 448, we get 6 with a remainder of 199.
Write down 6 as next digit of the result. 
Result so far: 136.0
Subtracting 2688 from 2887 leaves us with 199.
Include the next digit (2) from the dividend after 199, then repeat: 1992 / 448

Moving on to step 6:
When dividing 1992 by 448, we get 4 with a remainder of 200.
The next digit of our result is 4. 
Result so far: 1364.0
Subtract 1792 from 1992 to get 200.
Take the next digit (1) from the dividend and append it to 200, then repeat: 2001 / 448

Step 7:
When dividing 2001 by 448, we get 4 with a remainder of 209.
Record the quotient 4 as the next digit in the result. 
Result so far: 13644.0
If we take 1792 away from 2001, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 8:
448 can be fit into 2090 4 times, resulting in a remainder of 298.
Record the quotient 4 as the next digit in the result. 
Result so far: 13644.4
The remainder is 298 after subtracting 1792 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 9:
448 can be fit into 2980 6 times, resulting in a remainder of 292.
The number 6 becomes the next digit in our result. 
Result so far: 13644.46
If we subtract 2688 from 2980, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 10:
2920 divided by 448 is 6 with a remainder of 232.
Use 6 as the next digit of our solution. 
Result so far: 13644.466
Deduct 2688 from 2920 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Our division results in 13644.466 with a remaining 0.0232.
