Let's divide 72816505 by 173
We want to divide 72816505 by 173.

Let's proceed to step 1:
If we divide 7 by 173, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 173

Advancing to step 2:
173 can be fit into 72 0 times, resulting in a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (8) from the dividend after 72, then repeat: 728 / 173

On to step 3:
173 can be fit into 728 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 36 after subtracting 692 from 728.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 173

Going ahead to step 4:
361 divided by 173 is 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 346 from 361 leaves us with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 173

On to step 5:
173 can be fit into 156 0 times, resulting in a remainder of 156.
Put 0 as the next digit of the answer. 
Result so far: 420.0
If we take 0 away from 156, we end up with 156.
Append the next digit (5) from the dividend to 156 and continue with: 1565 / 173

Step 6:
If we divide 1565 by 173, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 4209.0
Subtract 1557 from 1565 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 173

Going ahead to step 7:
173 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 42090.0
Subtract 0 from 80 to get 80.
Grab the next digit (5) from the dividend, add it to 80, then carry on: 805 / 173

Step 8:
173 goes into 805 4 times with a remainder of 113.
Record the quotient 4 as the next digit in the result. 
Result so far: 420904.0
If we subtract 692 from 805, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 9:
When dividing 1130 by 173, we get 6 with a remainder of 92.
The next digit of our result is 6. 
Result so far: 420904.6
The remainder is 92 after subtracting 1038 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 10:
920 divided by 173 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 420904.65
Deduct 865 from 920 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 11:
The number 173 fits into 550 3 times, leaving a remainder of 31.
The next digit of our result is 3. 
Result so far: 420904.653
Deduct 519 from 550 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 12:
173 can be fit into 310 1 times, resulting in a remainder of 137.
Use 1 as the next digit of our solution. 
Result so far: 420904.6531
If we subtract 173 from 310, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 13:
If we divide 1370 by 173, we get 7 and a remainder of 159.
Record the quotient 7 as the next digit in the result. 
Result so far: 420904.65317
Deduct 1211 from 1370 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 14:
When dividing 1590 by 173, we get 9 with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 420904.653179
Subtract 1557 from 1590 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 15:
The number 173 fits into 330 1 times, leaving a remainder of 157.
Put 1 as the next digit of the answer. 
Result so far: 420904.6531791
Deduct 173 from 330 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 16:
173 goes into 1570 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 420904.65317919
Deduct 1557 from 1570 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 420904.65317919, with a leftover of 1.3e-08.
