166 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 166

Step 2:
166 goes into 52 0 times with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 166

Going ahead to step 3:
When dividing 524 by 166, we get 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 498 from 524 leaves us with 26.

166 goes into 269 1 times with a remainder of 103.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 166 away from 269, we end up with 103.
Include the next digit (4) from the dividend after 103, then repeat: 1034 / 166

Moving on to step 5:
166 goes into 1034 6 times with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 316.0
If we subtract 996 from 1034, we get 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 166

Advancing to step 6:
The number 166 fits into 389 2 times, leaving a remainder of 57.
The number 2 becomes the next digit in our result. 
Result so far: 3162.0
Deduct 332 from 389 and we're left with 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 166

Let's proceed to step 7:
166 goes into 575 3 times with a remainder of 77.
The number 3 becomes the next digit in our result.

Moving on to step 8:
The number 166 fits into 777 4 times, leaving a remainder of 113.
The number 4 becomes the next digit in our result. 
Result so far: 316234.0
Subtract 664 from 777 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 9:
166 can be fit into 1130 6 times, resulting in a remainder of 134.
Use 6 as the next digit of our solution. 
Result so far: 316234.6
If we subtract 996 from 1130, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 10:
When dividing 1340 by 166, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 316234.68
Subtracting 1328 from 1340 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
When dividing 120 by 166, we get 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 316234.68
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
The number 166 fits into 1200 7 times, leaving a remainder of 38.
The next digit of our result is 7. 
Result so far: 316234.6807
Subtracting 1162 from 1200 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
380 divided by 166 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 316234.68072
If we take 332 away from 380, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 14:
480 divided by 166 is 2 with a remainder of 148.
Record the quotient 2 as the next digit in the result. 
Result so far: 316234.680722
If we subtract 332 from 480, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Our division results in 316234.680722 with a remaining 1.48e-05.
