We're dividing 72019143 by 539 
We want to figure out the number of times 72019143 can be divided by 539.

Step 1:
7 divided by 539 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 539

On to step 2:
72 divided by 539 is 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 539

Advancing to step 3:
539 can be fit into 720 1 times, resulting in a remainder of 181.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 539 from 720 to get 181.
Grab the next digit (1) from the dividend, add it to 181, then carry on: 1811 / 539

Advancing to step 4:
The number 539 fits into 1811 3 times, leaving a remainder of 194.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1617 from 1811 leaves us with 194.
Grab the next digit (9) from the dividend, add it to 194, then carry on: 1949 / 539

On to step 5:
The number 539 fits into 1949 3 times, leaving a remainder of 332.
Write down 3 as next digit of the result. 
Result so far: 133.0
If we subtract 1617 from 1949, we get 332.
Grab the next digit (1) from the dividend, add it to 332, then carry on: 3321 / 539

Let's proceed to step 6:
539 can be fit into 3321 6 times, resulting in a remainder of 87.
Put 6 as the next digit of the answer. 
Result so far: 1336.0
If we take 3234 away from 3321, we end up with 87.
Take the next digit (4) from the dividend and append it to 87, then repeat: 874 / 539

On to step 7:
When dividing 874 by 539, we get 1 with a remainder of 335.
Record the quotient 1 as the next digit in the result. 
Result so far: 13361.0
Deduct 539 from 874 and we're left with 335.
Take the next digit (3) from the dividend and append it to 335, then repeat: 3353 / 539

Advancing to step 8:
3353 divided by 539 is 6 with a remainder of 119.
Put 6 as the next digit of the answer. 
Result so far: 133616.0
If we subtract 3234 from 3353, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 9:
539 can be fit into 1190 2 times, resulting in a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 133616.2
Subtracting 1078 from 1190 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 10:
1120 divided by 539 is 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 133616.22
If we take 1078 away from 1120, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 133616.22 with a remaining 0.042.
