We're dividing 7507258 by 166 
Our goal is to divide 7507258 by 166.

Step 1:
If we divide 7 by 166, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 166

Going ahead to step 2:
166 can be fit into 75 0 times, resulting in a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Grab the next digit (0) from the dividend, add it to 75, then carry on: 750 / 166

Step 3:
The number 166 fits into 750 4 times, leaving a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 86 after subtracting 664 from 750.
Include the next digit (7) from the dividend after 86, then repeat: 867 / 166

On to step 4:
When dividing 867 by 166, we get 5 with a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we subtract 830 from 867, we get 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 166

Advancing to step 5:
When dividing 372 by 166, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 452.0
If we take 332 away from 372, we end up with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 166

Moving on to step 6:
If we divide 405 by 166, we get 2 and a remainder of 73.
Record the quotient 2 as the next digit in the result. 
Result so far: 4522.0
If we subtract 332 from 405, we get 73.
Append the next digit (8) from the dividend to 73 and continue with: 738 / 166

Advancing to step 7:
When dividing 738 by 166, we get 4 with a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 45224.0
If we subtract 664 from 738, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 8:
166 can be fit into 740 4 times, resulting in a remainder of 76.
The next digit of our result is 4. 
Result so far: 45224.4
If we take 664 away from 740, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 9:
166 goes into 760 4 times with a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 45224.44
Subtract 664 from 760 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Our division results in 45224.44 with a remaining 0.096.
