We're dividing 66187173 by 264 
We want to divide 66187173 by 264.

Let's proceed to step 1:
If we divide 6 by 264, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 264

Advancing to step 2:
264 goes into 66 0 times with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 264

Let's proceed to step 3:
If we divide 661 by 264, we get 2 and a remainder of 133.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 528 away from 661, we end up with 133.
Bring next digit (8) of the dividend behind the 133 and repeat the process: 1338 / 264

Going ahead to step 4:
When dividing 1338 by 264, we get 5 with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 1320 from 1338 leaves us with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 264

Step 5:
When dividing 187 by 264, we get 0 with a remainder of 187.
The next digit of our result is 0. 
Result so far: 250.0
The remainder is 187 after subtracting 0 from 187.
Append the next digit (1) from the dividend to 187 and continue with: 1871 / 264

Moving on to step 6:
1871 divided by 264 is 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 2507.0
If we take 1848 away from 1871, we end up with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 264

On to step 7:
237 divided by 264 is 0 with a remainder of 237.
Write down 0 as next digit of the result. 
Result so far: 25070.0
Subtracting 0 from 237 leaves us with 237.
Bring next digit (3) of the dividend behind the 237 and repeat the process: 2373 / 264

Going ahead to step 8:
When dividing 2373 by 264, we get 8 with a remainder of 261.
The number 8 becomes the next digit in our result. 
Result so far: 250708.0
If we subtract 2112 from 2373, we get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Advancing to step 9:
264 goes into 2610 9 times with a remainder of 234.
The next digit of our result is 9. 
Result so far: 250708.9
The remainder is 234 after subtracting 2376 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 10:
If we divide 2340 by 264, we get 8 and a remainder of 228.
Put 8 as the next digit of the answer. 
Result so far: 250708.98
Subtract 2112 from 2340 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 11:
If we divide 2280 by 264, we get 8 and a remainder of 168.
Use 8 as the next digit of our solution. 
Result so far: 250708.988
The remainder is 168 after subtracting 2112 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final result is 250708.988 with a remainder of 0.0168.
