We divide 648521 by 88
We want to figure out the number of times 648521 can be divided by 88.

Step 1:
6 divided by 88 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 88

Let's proceed to step 2:
64 divided by 88 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 88

On to step 3:
If we divide 648 by 88, we get 7 and a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 32 after subtracting 616 from 648.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 88

Advancing to step 4:
88 goes into 325 3 times with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Subtracting 264 from 325 leaves us with 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 88

Step 5:
612 divided by 88 is 6 with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 736.0
Deduct 528 from 612 and we're left with 84.
Take the next digit (1) from the dividend and append it to 84, then repeat: 841 / 88

Advancing to step 6:
841 divided by 88 is 9 with a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 7369.0
The remainder is 49 after subtracting 792 from 841.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
The number 88 fits into 490 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 7369.5
Subtracting 440 from 490 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
500 divided by 88 is 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 7369.55
The remainder is 60 after subtracting 440 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 7369.55 and a remainder of 0.06.
