172939 ÷ 73 
We want to figure out the number of times 172939 can be divided by 73.

Let's proceed to step 1:
1 divided by 73 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 73

Step 2:
17 divided by 73 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 73

Step 3:
If we divide 172 by 73, we get 2 and a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 146 from 172 leaves us with 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 73

Step 4:
The number 73 fits into 269 3 times, leaving a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 219 from 269 to get 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 73

Let's proceed to step 5:
If we divide 503 by 73, we get 6 and a remainder of 65.
Record the quotient 6 as the next digit in the result. 
Result so far: 236.0
The remainder is 65 after subtracting 438 from 503.
Bring next digit (9) of the dividend behind the 65 and repeat the process: 659 / 73

Moving on to step 6:
659 divided by 73 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 2369.0
Deduct 657 from 659 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 divided by 73 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2369.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 73 is 2 with a remainder of 54.
The next digit of our result is 2. 
Result so far: 2369.02
Subtract 146 from 200 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
If we divide 540 by 73, we get 7 and a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 2369.027
Subtracting 511 from 540 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
290 divided by 73 is 3 with a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 2369.0273
If we subtract 219 from 290, we get 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 11:
73 can be fit into 710 9 times, resulting in a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 2369.02739
Subtract 657 from 710 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 12:
73 can be fit into 530 7 times, resulting in a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 2369.027397
Subtract 511 from 530 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
73 goes into 190 2 times with a remainder of 44.
The next digit of our result is 2. 
Result so far: 2369.0273972
Subtracting 146 from 190 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.

Let's proceed to step 14:
If we divide 440 by 73, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 2369.02739726
Deduct 438 from 440 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 2369.02739726 with a remainder of 2e-09.
