We're dividing 72153993 by 528 
Our goal is to divide 72153993 by 528.

Going ahead to step 1:
The number 528 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 528

Advancing to step 2:
528 can be fit into 72 0 times, resulting in a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 528

Step 3:
721 divided by 528 is 1 with a remainder of 193.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 528 from 721 leaves us with 193.
Take the next digit (5) from the dividend and append it to 193, then repeat: 1935 / 528

Step 4:
The number 528 fits into 1935 3 times, leaving a remainder of 351.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1584 away from 1935, we end up with 351.
Append the next digit (3) from the dividend to 351 and continue with: 3513 / 528

Going ahead to step 5:
528 goes into 3513 6 times with a remainder of 345.
The next digit of our result is 6. 
Result so far: 136.0
The remainder is 345 after subtracting 3168 from 3513.
Fetch the next digit (9) from the dividend, attach it to 345 and continue: 3459 / 528

Going ahead to step 6:
3459 divided by 528 is 6 with a remainder of 291.
The next digit of our result is 6. 
Result so far: 1366.0
If we take 3168 away from 3459, we end up with 291.
Fetch the next digit (9) from the dividend, attach it to 291 and continue: 2919 / 528

Step 7:
If we divide 2919 by 528, we get 5 and a remainder of 279.
The number 5 becomes the next digit in our result. 
Result so far: 13665.0
If we subtract 2640 from 2919, we get 279.
Bring next digit (3) of the dividend behind the 279 and repeat the process: 2793 / 528

Moving on to step 8:
2793 divided by 528 is 5 with a remainder of 153.
Record the quotient 5 as the next digit in the result. 
Result so far: 136655.0
If we subtract 2640 from 2793, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 9:
When dividing 1530 by 528, we get 2 with a remainder of 474.
Write down 2 as next digit of the result. 
Result so far: 136655.2
The remainder is 474 after subtracting 1056 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 10:
When dividing 4740 by 528, we get 8 with a remainder of 516.
Put 8 as the next digit of the answer. 
Result so far: 136655.28
Subtracting 4224 from 4740 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 11:
When dividing 5160 by 528, we get 9 with a remainder of 408.
The next digit of our result is 9. 
Result so far: 136655.289
If we subtract 4752 from 5160, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 12:
528 can be fit into 4080 7 times, resulting in a remainder of 384.
The next digit of our result is 7. 
Result so far: 136655.2897
If we take 3696 away from 4080, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 13:
528 goes into 3840 7 times with a remainder of 144.
The next digit of our result is 7. 
Result so far: 136655.28977
The remainder is 144 after subtracting 3696 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

After the division, we end up with 136655.28977 and a remainder of 0.000144.
