We're dividing 73912089 by 166 
We want to figure out the number of times 73912089 can be divided by 166.

Step 1:
166 goes into 7 0 times with 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.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 166

Let's proceed to step 2:
166 can be fit into 73 0 times, resulting in a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 166

Moving on to step 3:
166 can be fit into 739 4 times, resulting in a remainder of 75.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 664 from 739 and we're left with 75.
Grab the next digit (1) from the dividend, add it to 75, then carry on: 751 / 166

Going ahead to step 4:
751 divided by 166 is 4 with a remainder of 87.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtracting 664 from 751 leaves us with 87.
Include the next digit (2) from the dividend after 87, then repeat: 872 / 166

On to step 5:
166 goes into 872 5 times with a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 445.0
The remainder is 42 after subtracting 830 from 872.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 166

Advancing to step 6:
420 divided by 166 is 2 with a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 4452.0
If we subtract 332 from 420, we get 88.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 166

Moving on to step 7:
888 divided by 166 is 5 with a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 44525.0
Deduct 830 from 888 and we're left with 58.
Bring next digit (9) of the dividend behind the 58 and repeat the process: 589 / 166

Step 8:
When dividing 589 by 166, we get 3 with a remainder of 91.
Record the quotient 3 as the next digit in the result. 
Result so far: 445253.0
The remainder is 91 after subtracting 498 from 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 9:
When dividing 910 by 166, we get 5 with a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 445253.5
Subtract 830 from 910 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
800 divided by 166 is 4 with a remainder of 136.
Write down 4 as next digit of the result. 
Result so far: 445253.54
If we take 664 away from 800, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 11:
166 can be fit into 1360 8 times, resulting in a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 445253.548
Subtract 1328 from 1360 to 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.

On to step 12:
166 can be fit into 320 1 times, resulting in a remainder of 154.
Use 1 as the next digit of our solution. 
Result so far: 445253.5481
Subtracting 166 from 320 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 13:
When dividing 1540 by 166, we get 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 445253.54819
Deduct 1494 from 1540 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
166 goes into 460 2 times with a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 445253.548192
The remainder is 128 after subtracting 332 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 15:
166 goes into 1280 7 times with a remainder of 118.
Use 7 as the next digit of our solution. 
Result so far: 445253.5481927
Deduct 1162 from 1280 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 16:
If we divide 1180 by 166, we get 7 and a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 445253.54819277
If we subtract 1162 from 1180, 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.

Our division results in 445253.54819277 with a remaining 1.8e-08.
