We look at the division of 72168496 by 140 
Let's see how many times 140 fits into 72168496.

Advancing to step 1:
140 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 140

Going ahead to step 2:
The number 140 fits into 72 0 times, leaving a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 140

Advancing to step 3:
140 goes into 721 5 times with a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 700 away from 721, we end up with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 140

Step 4:
The number 140 fits into 216 1 times, leaving a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtract 140 from 216 to get 76.
Take the next digit (8) from the dividend and append it to 76, then repeat: 768 / 140

On to step 5:
140 can be fit into 768 5 times, resulting in a remainder of 68.
The number 5 becomes the next digit in our result. 
Result so far: 515.0
Deduct 700 from 768 and we're left with 68.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 140

On to step 6:
If we divide 684 by 140, we get 4 and a remainder of 124.
Write down 4 as next digit of the result. 
Result so far: 5154.0
The remainder is 124 after subtracting 560 from 684.
Bring next digit (9) of the dividend behind the 124 and repeat the process: 1249 / 140

Step 7:
1249 divided by 140 is 8 with a remainder of 129.
The number 8 becomes the next digit in our result. 
Result so far: 51548.0
The remainder is 129 after subtracting 1120 from 1249.
Grab the next digit (6) from the dividend, add it to 129, then carry on: 1296 / 140

Let's proceed to step 8:
When dividing 1296 by 140, we get 9 with a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 515489.0
The remainder is 36 after subtracting 1260 from 1296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
If we divide 360 by 140, we get 2 and a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 515489.2
Subtract 280 from 360 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.

Moving on to step 10:
800 divided by 140 is 5 with a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 515489.25
If we take 700 away from 800, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
140 can be fit into 1000 7 times, resulting in a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 515489.257
Subtract 980 from 1000 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
200 divided by 140 is 1 with a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 515489.2571
Subtracting 140 from 200 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
When dividing 600 by 140, we get 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 515489.25714
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
400 divided by 140 is 2 with a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 515489.257142
The remainder is 120 after subtracting 280 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 15:
140 can be fit into 1200 8 times, resulting in a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 515489.2571428
If we subtract 1120 from 1200, we 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.

Going ahead to step 16:
The number 140 fits into 800 5 times, leaving a remainder of 100.
The next digit of our result is 5. 
Result so far: 515489.25714285
If we subtract 700 from 800, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 515489.25714285 with a remainder of 1e-07.
