72996219 ÷ 525 
Our goal is to divide 72996219 by 525.

Going ahead to step 1:
When dividing 7 by 525, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 525

Advancing to step 2:
When dividing 72 by 525, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 525

Step 3:
If we divide 729 by 525, we get 1 and a remainder of 204.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 204 after subtracting 525 from 729.
Append the next digit (9) from the dividend to 204 and continue with: 2049 / 525

Moving on to step 4:
2049 divided by 525 is 3 with a remainder of 474.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 1575 from 2049, we get 474.
Append the next digit (6) from the dividend to 474 and continue with: 4746 / 525

Advancing to step 5:
4746 divided by 525 is 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 139.0
The remainder is 21 after subtracting 4725 from 4746.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 525

Advancing to step 6:
If we divide 212 by 525, we get 0 and a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 1390.0
The remainder is 212 after subtracting 0 from 212.
Take the next digit (1) from the dividend and append it to 212, then repeat: 2121 / 525

Going ahead to step 7:
The number 525 fits into 2121 4 times, leaving a remainder of 21.
The next digit of our result is 4. 
Result so far: 13904.0
Deduct 2100 from 2121 and we're left with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 525

Moving on to step 8:
If we divide 219 by 525, we get 0 and a remainder of 219.
The next digit of our result is 0. 
Result so far: 139040.0
Subtract 0 from 219 to get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Let's proceed to step 9:
The number 525 fits into 2190 4 times, leaving a remainder of 90.
Put 4 as the next digit of the answer. 
Result so far: 139040.4
Deduct 2100 from 2190 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
900 divided by 525 is 1 with a remainder of 375.
Write down 1 as next digit of the result. 
Result so far: 139040.41
If we subtract 525 from 900, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 11:
The number 525 fits into 3750 7 times, leaving a remainder of 75.
Use 7 as the next digit of our solution. 
Result so far: 139040.417
If we take 3675 away from 3750, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 12:
The number 525 fits into 750 1 times, leaving a remainder of 225.
Record the quotient 1 as the next digit in the result. 
Result so far: 139040.4171
If we take 525 away from 750, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 13:
The number 525 fits into 2250 4 times, leaving a remainder of 150.
The number 4 becomes the next digit in our result. 
Result so far: 139040.41714
If we take 2100 away from 2250, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 14:
1500 divided by 525 is 2 with a remainder of 450.
The next digit of our result is 2. 
Result so far: 139040.417142
If we take 1050 away from 1500, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 15:
If we divide 4500 by 525, we get 8 and a remainder of 300.
The next digit of our result is 8. 
Result so far: 139040.4171428
The remainder is 300 after subtracting 4200 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 16:
When dividing 3000 by 525, we get 5 with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 139040.41714285
Deduct 2625 from 3000 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

The quotient of the division is 139040.41714285, and the remainder is 3.75e-07.
