72577774 ÷ 754 
The aim is to understand the frequency of 754 in 72577774.

Let's proceed to step 1:
7 divided by 754 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 754

Step 2:
754 goes into 72 0 times with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Fetch the next digit (5) from the dividend, attach it to 72 and continue: 725 / 754

Let's proceed to step 3:
725 divided by 754 is 0 with a remainder of 725.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 725, we get 725.
Bring next digit (7) of the dividend behind the 725 and repeat the process: 7257 / 754

Advancing to step 4:
If we divide 7257 by 754, we get 9 and a remainder of 471.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 6786 from 7257 leaves us with 471.
Append the next digit (7) from the dividend to 471 and continue with: 4717 / 754

Step 5:
754 can be fit into 4717 6 times, resulting in a remainder of 193.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we subtract 4524 from 4717, we get 193.
Fetch the next digit (7) from the dividend, attach it to 193 and continue: 1937 / 754

Step 6:
The number 754 fits into 1937 2 times, leaving a remainder of 429.
The number 2 becomes the next digit in our result. 
Result so far: 962.0
If we subtract 1508 from 1937, we get 429.
Grab the next digit (7) from the dividend, add it to 429, then carry on: 4297 / 754

Moving on to step 7:
754 can be fit into 4297 5 times, resulting in a remainder of 527.
The number 5 becomes the next digit in our result. 
Result so far: 9625.0
If we subtract 3770 from 4297, we get 527.
Take the next digit (4) from the dividend and append it to 527, then repeat: 5274 / 754

Moving on to step 8:
The number 754 fits into 5274 6 times, leaving a remainder of 750.
Record the quotient 6 as the next digit in the result. 
Result so far: 96256.0
If we subtract 4524 from 5274, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Step 9:
754 goes into 7500 9 times with a remainder of 714.
Record the quotient 9 as the next digit in the result. 
Result so far: 96256.9
The remainder is 714 after subtracting 6786 from 7500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Step 10:
The number 754 fits into 7140 9 times, leaving a remainder of 354.
Use 9 as the next digit of our solution. 
Result so far: 96256.99
The remainder is 354 after subtracting 6786 from 7140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

After the division, we end up with 96256.99 and a remainder of 0.354.
