We look at the division of 72988732 by 522 
We want to divide 72988732 by 522.

Step 1:
522 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 522

Advancing to step 2:
The number 522 fits into 72 0 times, leaving a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 522

Let's proceed to step 3:
522 goes into 729 1 times with a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 522 from 729, we get 207.
Bring next digit (8) of the dividend behind the 207 and repeat the process: 2078 / 522

Going ahead to step 4:
The number 522 fits into 2078 3 times, leaving a remainder of 512.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1566 from 2078, we get 512.
Take the next digit (8) from the dividend and append it to 512, then repeat: 5128 / 522

Moving on to step 5:
5128 divided by 522 is 9 with a remainder of 430.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
Subtract 4698 from 5128 to get 430.
Bring next digit (7) of the dividend behind the 430 and repeat the process: 4307 / 522

On to step 6:
The number 522 fits into 4307 8 times, leaving a remainder of 131.
Write down 8 as next digit of the result. 
Result so far: 1398.0
The remainder is 131 after subtracting 4176 from 4307.
Fetch the next digit (3) from the dividend, attach it to 131 and continue: 1313 / 522

Step 7:
1313 divided by 522 is 2 with a remainder of 269.
Write down 2 as next digit of the result. 
Result so far: 13982.0
Subtracting 1044 from 1313 leaves us with 269.
Include the next digit (2) from the dividend after 269, then repeat: 2692 / 522

On to step 8:
If we divide 2692 by 522, we get 5 and a remainder of 82.
Write down 5 as next digit of the result. 
Result so far: 139825.0
Subtract 2610 from 2692 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 9:
The number 522 fits into 820 1 times, leaving a remainder of 298.
The next digit of our result is 1. 
Result so far: 139825.1
If we take 522 away from 820, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 10:
When dividing 2980 by 522, we get 5 with a remainder of 370.
The number 5 becomes the next digit in our result. 
Result so far: 139825.15
If we take 2610 away from 2980, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 11:
The number 522 fits into 3700 7 times, leaving a remainder of 46.
Put 7 as the next digit of the answer. 
Result so far: 139825.157
The remainder is 46 after subtracting 3654 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
If we divide 460 by 522, we get 0 and a remainder of 460.
Write down 0 as next digit of the result. 
Result so far: 139825.157
If we subtract 0 from 460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 13:
522 goes into 4600 8 times with a remainder of 424.
Write down 8 as next digit of the result. 
Result so far: 139825.15708
Subtracting 4176 from 4600 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 14:
The number 522 fits into 4240 8 times, leaving a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 139825.157088
The remainder is 64 after subtracting 4176 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 139825.157088 with a remainder of 6.4e-06.
