We look at the division of 43184403 by 166 
We want to divide 43184403 by 166.

Step 1:
When dividing 4 by 166, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 166

Going ahead to step 2:
166 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 166

Let's proceed to step 3:
166 goes into 431 2 times with a remainder of 99.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 332 from 431 leaves us with 99.
Bring next digit (8) of the dividend behind the 99 and repeat the process: 998 / 166

Moving on to step 4:
166 goes into 998 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 2 after subtracting 996 from 998.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 166

Let's proceed to step 5:
24 divided by 166 is 0 with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 260.0
If we subtract 0 from 24, we get 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 166

Going ahead to step 6:
The number 166 fits into 244 1 times, leaving a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 2601.0
Subtracting 166 from 244 leaves us with 78.
Take the next digit (0) from the dividend and append it to 78, then repeat: 780 / 166

Moving on to step 7:
166 goes into 780 4 times with a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 26014.0
Subtract 664 from 780 to get 116.
Append the next digit (3) from the dividend to 116 and continue with: 1163 / 166

Moving on to step 8:
If we divide 1163 by 166, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 260147.0
The remainder is 1 after subtracting 1162 from 1163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
When dividing 10 by 166, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 260147.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 166 is 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 260147.0
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 260147.0 with a remainder of 0.1.
