66500381 divided by 525 
We want to figure out the number of times 66500381 can be divided by 525.

Step 1:
If we divide 6 by 525, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 525

On to step 2:
If we divide 66 by 525, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 525

On to step 3:
When dividing 665 by 525, we get 1 with a remainder of 140.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 525 from 665, we get 140.
Fetch the next digit (0) from the dividend, attach it to 140 and continue: 1400 / 525

Going ahead to step 4:
The number 525 fits into 1400 2 times, leaving a remainder of 350.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 1050 from 1400 leaves us with 350.
Include the next digit (0) from the dividend after 350, then repeat: 3500 / 525

Moving on to step 5:
3500 divided by 525 is 6 with a remainder of 350.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
The remainder is 350 after subtracting 3150 from 3500.
Include the next digit (3) from the dividend after 350, then repeat: 3503 / 525

Let's proceed to step 6:
When dividing 3503 by 525, we get 6 with a remainder of 353.
The number 6 becomes the next digit in our result. 
Result so far: 1266.0
Deduct 3150 from 3503 and we're left with 353.
Take the next digit (8) from the dividend and append it to 353, then repeat: 3538 / 525

Let's proceed to step 7:
The number 525 fits into 3538 6 times, leaving a remainder of 388.
Write down 6 as next digit of the result. 
Result so far: 12666.0
Subtract 3150 from 3538 to get 388.
Include the next digit (1) from the dividend after 388, then repeat: 3881 / 525

On to step 8:
If we divide 3881 by 525, we get 7 and a remainder of 206.
Put 7 as the next digit of the answer. 
Result so far: 126667.0
Deduct 3675 from 3881 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 9:
2060 divided by 525 is 3 with a remainder of 485.
The next digit of our result is 3. 
Result so far: 126667.3
Subtract 1575 from 2060 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

On to step 10:
525 goes into 4850 9 times with a remainder of 125.
Use 9 as the next digit of our solution. 
Result so far: 126667.39
Subtract 4725 from 4850 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 11:
The number 525 fits into 1250 2 times, leaving a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 126667.392
The remainder is 200 after subtracting 1050 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
2000 divided by 525 is 3 with a remainder of 425.
Write down 3 as next digit of the result. 
Result so far: 126667.3923
Subtract 1575 from 2000 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 13:
If we divide 4250 by 525, we get 8 and a remainder of 50.
The next digit of our result is 8. 
Result so far: 126667.39238
If we subtract 4200 from 4250, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
If we divide 500 by 525, we get 0 and a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 126667.39238
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 15:
If we divide 5000 by 525, we get 9 and a remainder of 275.
The number 9 becomes the next digit in our result. 
Result so far: 126667.3923809
Subtracting 4725 from 5000 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 16:
525 goes into 2750 5 times with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 126667.39238095
If we subtract 2625 from 2750, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The final result is 126667.39238095 with a remainder of 1.25e-07.
