54087328 ÷ 166 
We want to figure out the number of times 54087328 can be divided by 166.

Going ahead to step 1:
If we divide 5 by 166, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 166

Step 2:
166 goes into 54 0 times with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Append the next digit (0) from the dividend to 54 and continue with: 540 / 166

Going ahead to step 3:
The number 166 fits into 540 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 498 from 540, we get 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 166

Moving on to step 4:
428 divided by 166 is 2 with a remainder of 96.
The next digit of our result is 2. 
Result so far: 32.0
If we subtract 332 from 428, we get 96.
Bring next digit (7) of the dividend behind the 96 and repeat the process: 967 / 166

Let's proceed to step 5:
166 goes into 967 5 times with a remainder of 137.
The number 5 becomes the next digit in our result. 
Result so far: 325.0
Subtracting 830 from 967 leaves us with 137.
Take the next digit (3) from the dividend and append it to 137, then repeat: 1373 / 166

On to step 6:
When dividing 1373 by 166, we get 8 with a remainder of 45.
The next digit of our result is 8. 
Result so far: 3258.0
If we take 1328 away from 1373, we end up with 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 166

Step 7:
452 divided by 166 is 2 with a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 32582.0
Subtract 332 from 452 to get 120.
Include the next digit (8) from the dividend after 120, then repeat: 1208 / 166

Moving on to step 8:
166 goes into 1208 7 times with a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 325827.0
The remainder is 46 after subtracting 1162 from 1208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
When dividing 460 by 166, we get 2 with a remainder of 128.
The next digit of our result is 2. 
Result so far: 325827.2
The remainder is 128 after subtracting 332 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 10:
The number 166 fits into 1280 7 times, leaving a remainder of 118.
Record the quotient 7 as the next digit in the result. 
Result so far: 325827.27
Subtract 1162 from 1280 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 11:
1180 divided by 166 is 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 325827.277
If we take 1162 away from 1180, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 325827.277 with a remainder of 0.0018.
