Let's divide 642528 by 88
The aim is to understand the frequency of 88 in 642528.

On to step 1:
6 divided by 88 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 88

Step 2:
64 divided by 88 is 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 88

Let's proceed to step 3:
88 goes into 642 7 times with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 616 away from 642, we end up with 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 88

Step 4:
88 can be fit into 265 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 73.0
If we take 264 away from 265, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 88

On to step 5:
88 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 730.0
Subtract 0 from 12 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 88

Moving on to step 6:
128 divided by 88 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 7301.0
If we subtract 88 from 128, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
88 goes into 400 4 times with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 7301.4
Subtract 352 from 400 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
If we divide 480 by 88, we get 5 and a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 7301.45
The remainder is 40 after subtracting 440 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 88, we get 4 and a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 7301.454
Subtract 352 from 400 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
The number 88 fits into 480 5 times, leaving a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 7301.4545
Deduct 440 from 480 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
88 can be fit into 400 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 7301.45454
If we take 352 away from 400, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
If we divide 480 by 88, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 7301.454545
If we subtract 440 from 480, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
When dividing 400 by 88, we get 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 7301.4545454
Subtracting 352 from 400 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 14:
88 goes into 480 5 times with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 7301.45454545
The remainder is 40 after subtracting 440 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 7301.45454545 and a remainder of 4e-08.
