We're dividing 621325 by 88 
The aim is to understand the frequency of 88 in 621325.

Advancing to step 1:
The number 88 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 88

On to step 2:
62 divided by 88 is 0 with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 88

Step 3:
The number 88 fits into 621 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 5 after subtracting 616 from 621.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 88

Advancing to step 4:
88 can be fit into 53 0 times, resulting in a remainder of 53.
The next digit of our result is 0. 
Result so far: 70.0
If we take 0 away from 53, we end up with 53.
Include the next digit (2) from the dividend after 53, then repeat: 532 / 88

Let's proceed to step 5:
When dividing 532 by 88, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 706.0
Subtract 528 from 532 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 88

Step 6:
88 can be fit into 45 0 times, resulting in a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 7060.0
Subtract 0 from 45 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
450 divided by 88 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 7060.5
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
88 can be fit into 100 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 7060.51
If we take 88 away from 100, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
If we divide 120 by 88, we get 1 and a remainder of 32.
The next digit of our result is 1. 
Result so far: 7060.511
The remainder is 32 after subtracting 88 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 7060.511 and a remainder of 0.0032.
