72699105 divided by 166 
We want to figure out the number of times 72699105 can be divided by 166.

Step 1:
The number 166 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 166

Going ahead to step 2:
The number 166 fits into 72 0 times, leaving a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Fetch the next digit (6) from the dividend, attach it to 72 and continue: 726 / 166

Let's proceed to step 3:
The number 166 fits into 726 4 times, leaving a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 664 from 726 and we're left with 62.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 166

Advancing to step 4:
629 divided by 166 is 3 with a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 498 from 629 leaves us with 131.
Fetch the next digit (9) from the dividend, attach it to 131 and continue: 1319 / 166

On to step 5:
166 can be fit into 1319 7 times, resulting in a remainder of 157.
Use 7 as the next digit of our solution. 
Result so far: 437.0
If we take 1162 away from 1319, we end up with 157.
Take the next digit (1) from the dividend and append it to 157, then repeat: 1571 / 166

Going ahead to step 6:
166 can be fit into 1571 9 times, resulting in a remainder of 77.
Write down 9 as next digit of the result. 
Result so far: 4379.0
The remainder is 77 after subtracting 1494 from 1571.
Fetch the next digit (0) from the dividend, attach it to 77 and continue: 770 / 166

Moving on to step 7:
When dividing 770 by 166, we get 4 with a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 43794.0
If we subtract 664 from 770, we get 106.
Take the next digit (5) from the dividend and append it to 106, then repeat: 1065 / 166

On to step 8:
166 can be fit into 1065 6 times, resulting in a remainder of 69.
The number 6 becomes the next digit in our result. 
Result so far: 437946.0
Deduct 996 from 1065 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 9:
690 divided by 166 is 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 437946.4
The remainder is 26 after subtracting 664 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
When dividing 260 by 166, we get 1 with a remainder of 94.
The next digit of our result is 1. 
Result so far: 437946.41
The remainder is 94 after subtracting 166 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 11:
If we divide 940 by 166, we get 5 and a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 437946.415
Subtract 830 from 940 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
166 goes into 1100 6 times with a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 437946.4156
The remainder is 104 after subtracting 996 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 13:
1040 divided by 166 is 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 437946.41566
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.

After the division, we end up with 437946.41566 and a remainder of 4.4e-05.
