725390 ÷ 88 
The aim is to understand the frequency of 88 in 725390.

Going ahead to step 1:
The number 88 fits into 7 0 times, leaving 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.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 88

Moving on to step 2:
72 divided by 88 is 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 88

Going ahead to step 3:
88 goes into 725 8 times with a remainder of 21.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 704 from 725 leaves us with 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 88

Advancing to step 4:
The number 88 fits into 213 2 times, leaving a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 82.0
Deduct 176 from 213 and we're left with 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 88

Step 5:
379 divided by 88 is 4 with a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 824.0
Subtracting 352 from 379 leaves us with 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 88

Let's proceed to step 6:
88 can be fit into 270 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 8243.0
The remainder is 6 after subtracting 264 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
88 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 8243.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
The number 88 fits into 600 6 times, leaving a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 8243.06
Deduct 528 from 600 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
720 divided by 88 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 8243.068
Subtracting 704 from 720 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
When dividing 160 by 88, we get 1 with a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 8243.0681
Subtracting 88 from 160 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
The number 88 fits into 720 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 8243.06818
Subtracting 704 from 720 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
If we divide 160 by 88, we get 1 and a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 8243.068181
Deduct 88 from 160 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
88 goes into 720 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 8243.0681818
If we take 704 away from 720, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
88 goes into 160 1 times with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 8243.06818181
Subtracting 88 from 160 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 8243.06818181 and a remainder of 7.2e-08.
