74563050 ÷ 166 
Our goal is to divide 74563050 by 166.

Advancing to step 1:
If we divide 7 by 166, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 166

Step 2:
74 divided by 166 is 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Bring next digit (5) of the dividend behind the 74 and repeat the process: 745 / 166

Going ahead to step 3:
745 divided by 166 is 4 with a remainder of 81.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 664 from 745 to get 81.
Include the next digit (6) from the dividend after 81, then repeat: 816 / 166

Going ahead to step 4:
166 goes into 816 4 times with a remainder of 152.
The next digit of our result is 4. 
Result so far: 44.0
If we subtract 664 from 816, we get 152.
Fetch the next digit (3) from the dividend, attach it to 152 and continue: 1523 / 166

Going ahead to step 5:
The number 166 fits into 1523 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 449.0
Deduct 1494 from 1523 and we're left with 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 166

Advancing to step 6:
166 goes into 290 1 times with a remainder of 124.
Record the quotient 1 as the next digit in the result. 
Result so far: 4491.0
Subtracting 166 from 290 leaves us with 124.
Append the next digit (5) from the dividend to 124 and continue with: 1245 / 166

Step 7:
1245 divided by 166 is 7 with a remainder of 83.
Write down 7 as next digit of the result. 
Result so far: 44917.0
Subtract 1162 from 1245 to get 83.
Grab the next digit (0) from the dividend, add it to 83, then carry on: 830 / 166

Going ahead to step 8:
If we divide 830 by 166, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 449175.0
Subtracting 830 from 830 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 166 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 449175.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 166 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 449175.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 449175.0 with a remainder of 0.0.
