91436174 ÷ 666 
Let's see how many times 666 fits into 91436174.

Step 1:
When dividing 9 by 666, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 666

Step 2:
91 divided by 666 is 0 with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Append the next digit (4) from the dividend to 91 and continue with: 914 / 666

Moving on to step 3:
666 can be fit into 914 1 times, resulting in a remainder of 248.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 666 from 914, we get 248.
Append the next digit (3) from the dividend to 248 and continue with: 2483 / 666

Advancing to step 4:
2483 divided by 666 is 3 with a remainder of 485.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 1998 from 2483 leaves us with 485.
Bring next digit (6) of the dividend behind the 485 and repeat the process: 4856 / 666

Going ahead to step 5:
4856 divided by 666 is 7 with a remainder of 194.
Write down 7 as next digit of the result. 
Result so far: 137.0
Subtract 4662 from 4856 to get 194.
Fetch the next digit (1) from the dividend, attach it to 194 and continue: 1941 / 666

Step 6:
If we divide 1941 by 666, we get 2 and a remainder of 609.
The number 2 becomes the next digit in our result. 
Result so far: 1372.0
Subtracting 1332 from 1941 leaves us with 609.
Include the next digit (7) from the dividend after 609, then repeat: 6097 / 666

Advancing to step 7:
If we divide 6097 by 666, we get 9 and a remainder of 103.
Write down 9 as next digit of the result. 
Result so far: 13729.0
Subtract 5994 from 6097 to get 103.
Grab the next digit (4) from the dividend, add it to 103, then carry on: 1034 / 666

Let's proceed to step 8:
If we divide 1034 by 666, we get 1 and a remainder of 368.
The next digit of our result is 1. 
Result so far: 137291.0
If we subtract 666 from 1034, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 9:
3680 divided by 666 is 5 with a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 137291.5
Subtract 3330 from 3680 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 10:
If we divide 3500 by 666, we get 5 and a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 137291.55
Deduct 3330 from 3500 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final result is 137291.55 with a remainder of 0.17.
