We look at the division of 66274332 by 166 
We want to figure out the number of times 66274332 can be divided by 166.

On to step 1:
The number 166 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 166

Step 2:
166 can be fit into 66 0 times, resulting in a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (2) from the dividend, add it to 66, then carry on: 662 / 166

Moving on to step 3:
166 can be fit into 662 3 times, resulting in a remainder of 164.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 498 from 662 and we're left with 164.
Include the next digit (7) from the dividend after 164, then repeat: 1647 / 166

Let's proceed to step 4:
166 goes into 1647 9 times with a remainder of 153.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 1494 from 1647 to get 153.
Bring next digit (4) of the dividend behind the 153 and repeat the process: 1534 / 166

Advancing to step 5:
166 can be fit into 1534 9 times, resulting in a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 399.0
Subtract 1494 from 1534 to get 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 166

Moving on to step 6:
403 divided by 166 is 2 with a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 3992.0
If we take 332 away from 403, we end up with 71.
Take the next digit (3) from the dividend and append it to 71, then repeat: 713 / 166

Step 7:
166 goes into 713 4 times with a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 39924.0
Subtract 664 from 713 to get 49.
Bring next digit (2) of the dividend behind the 49 and repeat the process: 492 / 166

Advancing to step 8:
If we divide 492 by 166, we get 2 and a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 399242.0
Subtracting 332 from 492 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 9:
If we divide 1600 by 166, we get 9 and a remainder of 106.
Put 9 as the next digit of the answer. 
Result so far: 399242.9
The remainder is 106 after subtracting 1494 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 10:
When dividing 1060 by 166, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 399242.96
If we subtract 996 from 1060, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
166 goes into 640 3 times with a remainder of 142.
Use 3 as the next digit of our solution. 
Result so far: 399242.963
Subtract 498 from 640 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 12:
When dividing 1420 by 166, we get 8 with a remainder of 92.
Use 8 as the next digit of our solution. 
Result so far: 399242.9638
Subtracting 1328 from 1420 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 13:
If we divide 920 by 166, we get 5 and a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 399242.96385
If we subtract 830 from 920, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 14:
When dividing 900 by 166, we get 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 399242.963855
Subtract 830 from 900 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 399242.963855 with a remainder of 7e-06.
