166224 ÷ 43 
We want to figure out the number of times 166224 can be divided by 43.

Let's proceed to step 1:
When dividing 1 by 43, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 43

On to step 2:
16 divided by 43 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 43

Step 3:
The number 43 fits into 166 3 times, leaving a remainder of 37.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 37 after subtracting 129 from 166.
Append the next digit (2) from the dividend to 37 and continue with: 372 / 43

Moving on to step 4:
43 can be fit into 372 8 times, resulting in a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we subtract 344 from 372, we get 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 43

On to step 5:
43 goes into 282 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 386.0
Deduct 258 from 282 and we're left with 24.
Bring next digit (4) of the dividend behind the 24 and repeat the process: 244 / 43

Going ahead to step 6:
If we divide 244 by 43, we get 5 and a remainder of 29.
Use 5 as the next digit of our solution. 
Result so far: 3865.0
The remainder is 29 after subtracting 215 from 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
43 goes into 290 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 3865.6
If we subtract 258 from 290, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
When dividing 320 by 43, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 3865.67
Subtracting 301 from 320 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
The number 43 fits into 190 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 3865.674
If we subtract 172 from 190, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
If we divide 180 by 43, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 3865.6744
If we subtract 172 from 180, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 3865.6744, and the remainder is 8e-05.
