81606179 ÷ 173 
We want to figure out the number of times 81606179 can be divided by 173.

Let's proceed to step 1:
The number 173 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 173

Moving on to step 2:
When dividing 81 by 173, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (6) of the dividend behind the 81 and repeat the process: 816 / 173

Advancing to step 3:
If we divide 816 by 173, we get 4 and a remainder of 124.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 124 after subtracting 692 from 816.
Bring next digit (0) of the dividend behind the 124 and repeat the process: 1240 / 173

Going ahead to step 4:
173 can be fit into 1240 7 times, resulting in a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we subtract 1211 from 1240, we get 29.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 173

Moving on to step 5:
173 can be fit into 296 1 times, resulting in a remainder of 123.
Put 1 as the next digit of the answer. 
Result so far: 471.0
Subtracting 173 from 296 leaves us with 123.
Append the next digit (1) from the dividend to 123 and continue with: 1231 / 173

Let's proceed to step 6:
173 can be fit into 1231 7 times, resulting in a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 4717.0
The remainder is 20 after subtracting 1211 from 1231.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 173

Step 7:
If we divide 207 by 173, we get 1 and a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 47171.0
The remainder is 34 after subtracting 173 from 207.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 173

Step 8:
If we divide 349 by 173, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 471712.0
Deduct 346 from 349 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
173 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 471712.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
When dividing 300 by 173, we get 1 with a remainder of 127.
Record the quotient 1 as the next digit in the result. 
Result so far: 471712.01
The remainder is 127 after subtracting 173 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 11:
1270 divided by 173 is 7 with a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 471712.017
Subtracting 1211 from 1270 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 12:
When dividing 590 by 173, we get 3 with a remainder of 71.
Write down 3 as next digit of the result. 
Result so far: 471712.0173
Deduct 519 from 590 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 13:
If we divide 710 by 173, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 471712.01734
Subtract 692 from 710 to 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.

Moving on to step 14:
If we divide 180 by 173, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 471712.017341
Subtracting 173 from 180 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 15:
When dividing 70 by 173, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 471712.017341
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 16:
173 can be fit into 700 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 471712.01734104
The remainder is 8 after subtracting 692 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 471712.01734104 and a remainder of 8e-09.
