Let's divide 72891690 by 166
Our goal is to divide 72891690 by 166.

On to step 1:
The number 166 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 166

Moving on to step 2:
166 can be fit into 72 0 times, resulting in a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Fetch the next digit (8) from the dividend, attach it to 72 and continue: 728 / 166

Let's proceed to step 3:
If we divide 728 by 166, we get 4 and a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 664 from 728 and we're left with 64.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 166

Moving on to step 4:
If we divide 649 by 166, we get 3 and a remainder of 151.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 498 from 649, we get 151.
Bring next digit (1) of the dividend behind the 151 and repeat the process: 1511 / 166

Step 5:
1511 divided by 166 is 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 439.0
If we subtract 1494 from 1511, we get 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 166

Going ahead to step 6:
176 divided by 166 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 4391.0
The remainder is 10 after subtracting 166 from 176.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 166

Moving on to step 7:
When dividing 109 by 166, we get 0 with a remainder of 109.
The number 0 becomes the next digit in our result. 
Result so far: 43910.0
The remainder is 109 after subtracting 0 from 109.
Grab the next digit (0) from the dividend, add it to 109, then carry on: 1090 / 166

Step 8:
1090 divided by 166 is 6 with a remainder of 94.
The number 6 becomes the next digit in our result. 
Result so far: 439106.0
Subtracting 996 from 1090 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 9:
166 can be fit into 940 5 times, resulting in a remainder of 110.
The next digit of our result is 5. 
Result so far: 439106.5
Subtracting 830 from 940 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
166 goes into 1100 6 times with a remainder of 104.
Record the quotient 6 as the next digit in the result. 
Result so far: 439106.56
If we subtract 996 from 1100, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 11:
The number 166 fits into 1040 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 439106.566
Subtracting 996 from 1040 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 439106.566 with a remaining 0.0044.
