666434 divided by 88 
Our goal is to divide 666434 by 88.

Advancing to step 1:
If we divide 6 by 88, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 88

Step 2:
The number 88 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 88

Going ahead to step 3:
666 divided by 88 is 7 with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 616 from 666, we get 50.
Grab the next digit (4) from the dividend, add it to 50, then carry on: 504 / 88

Let's proceed to step 4:
If we divide 504 by 88, we get 5 and a remainder of 64.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtracting 440 from 504 leaves us with 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 88

Going ahead to step 5:
When dividing 643 by 88, we get 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 757.0
Subtracting 616 from 643 leaves us with 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 88

On to step 6:
88 goes into 274 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 7573.0
If we take 264 away from 274, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
If we divide 100 by 88, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 7573.1
Subtract 88 from 100 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
When dividing 120 by 88, we get 1 with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 7573.11
Deduct 88 from 120 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 7573.11, with a leftover of 0.032.
