85668606 ÷ 664 
We're looking to find how many times 664 goes into 85668606.

Going ahead to step 1:
664 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 664

On to step 2:
664 goes into 85 0 times with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Bring next digit (6) of the dividend behind the 85 and repeat the process: 856 / 664

Moving on to step 3:
664 can be fit into 856 1 times, resulting in a remainder of 192.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 664 from 856, we get 192.
Bring next digit (6) of the dividend behind the 192 and repeat the process: 1926 / 664

Moving on to step 4:
The number 664 fits into 1926 2 times, leaving a remainder of 598.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1328 from 1926 to get 598.
Include the next digit (8) from the dividend after 598, then repeat: 5988 / 664

Advancing to step 5:
664 goes into 5988 9 times with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 129.0
The remainder is 12 after subtracting 5976 from 5988.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 664

Step 6:
664 can be fit into 126 0 times, resulting in a remainder of 126.
The next digit of our result is 0. 
Result so far: 1290.0
Subtracting 0 from 126 leaves us with 126.
Fetch the next digit (0) from the dividend, attach it to 126 and continue: 1260 / 664

Going ahead to step 7:
When dividing 1260 by 664, we get 1 with a remainder of 596.
Write down 1 as next digit of the result. 
Result so far: 12901.0
Deduct 664 from 1260 and we're left with 596.
Include the next digit (6) from the dividend after 596, then repeat: 5966 / 664

On to step 8:
If we divide 5966 by 664, we get 8 and a remainder of 654.
Write down 8 as next digit of the result. 
Result so far: 129018.0
If we take 5312 away from 5966, we end up with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Moving on to step 9:
When dividing 6540 by 664, we get 9 with a remainder of 564.
Use 9 as the next digit of our solution. 
Result so far: 129018.9
Subtracting 5976 from 6540 leaves us with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Advancing to step 10:
If we divide 5640 by 664, we get 8 and a remainder of 328.
Write down 8 as next digit of the result. 
Result so far: 129018.98
If we subtract 5312 from 5640, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 11:
664 goes into 3280 4 times with a remainder of 624.
Record the quotient 4 as the next digit in the result. 
Result so far: 129018.984
Subtract 2656 from 3280 to get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Step 12:
The number 664 fits into 6240 9 times, leaving a remainder of 264.
The number 9 becomes the next digit in our result. 
Result so far: 129018.9849
Deduct 5976 from 6240 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 13:
664 can be fit into 2640 3 times, resulting in a remainder of 648.
Record the quotient 3 as the next digit in the result. 
Result so far: 129018.98493
The remainder is 648 after subtracting 1992 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Let's proceed to step 14:
6480 divided by 664 is 9 with a remainder of 504.
Write down 9 as next digit of the result. 
Result so far: 129018.984939
The remainder is 504 after subtracting 5976 from 6480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 15:
If we divide 5040 by 664, we get 7 and a remainder of 392.
Write down 7 as next digit of the result. 
Result so far: 129018.9849397
If we subtract 4648 from 5040, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 16:
If we divide 3920 by 664, we get 5 and a remainder of 600.
The next digit of our result is 5. 
Result so far: 129018.98493975
If we subtract 3320 from 3920, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 129018.98493975 with a remainder of 6e-07.
