We're dividing 91997576 by 664 
We're looking to find how many times 664 goes into 91997576.

Going ahead to step 1:
664 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 664

Moving on to step 2:
If we divide 91 by 664, we get 0 and a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Grab the next digit (9) from the dividend, add it to 91, then carry on: 919 / 664

Step 3:
When dividing 919 by 664, we get 1 with a remainder of 255.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 664 from 919 to get 255.
Append the next digit (9) from the dividend to 255 and continue with: 2559 / 664

Step 4:
The number 664 fits into 2559 3 times, leaving a remainder of 567.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1992 from 2559 to get 567.
Fetch the next digit (7) from the dividend, attach it to 567 and continue: 5677 / 664

On to step 5:
When dividing 5677 by 664, we get 8 with a remainder of 365.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we take 5312 away from 5677, we end up with 365.
Bring next digit (5) of the dividend behind the 365 and repeat the process: 3655 / 664

Let's proceed to step 6:
664 can be fit into 3655 5 times, resulting in a remainder of 335.
Use 5 as the next digit of our solution. 
Result so far: 1385.0
Deduct 3320 from 3655 and we're left with 335.
Take the next digit (7) from the dividend and append it to 335, then repeat: 3357 / 664

Step 7:
664 can be fit into 3357 5 times, resulting in a remainder of 37.
The next digit of our result is 5. 
Result so far: 13855.0
If we take 3320 away from 3357, we end up with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 664

Going ahead to step 8:
664 can be fit into 376 0 times, resulting in a remainder of 376.
Put 0 as the next digit of the answer. 
Result so far: 138550.0
Subtracting 0 from 376 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 9:
When dividing 3760 by 664, we get 5 with a remainder of 440.
The number 5 becomes the next digit in our result. 
Result so far: 138550.5
Deduct 3320 from 3760 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 10:
4400 divided by 664 is 6 with a remainder of 416.
Record the quotient 6 as the next digit in the result. 
Result so far: 138550.56
Subtracting 3984 from 4400 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 11:
The number 664 fits into 4160 6 times, leaving a remainder of 176.
Record the quotient 6 as the next digit in the result. 
Result so far: 138550.566
If we subtract 3984 from 4160, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final outcome is 138550.566, with a leftover of 0.0176.
