We're dividing 77971443 by 525 
Let's see how many times 525 fits into 77971443.

Advancing to step 1:
When dividing 7 by 525, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 525

Going ahead to step 2:
If we divide 77 by 525, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (9) from the dividend and append it to 77, then repeat: 779 / 525

Advancing to step 3:
525 goes into 779 1 times with a remainder of 254.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 525 from 779 to get 254.
Include the next digit (7) from the dividend after 254, then repeat: 2547 / 525

Going ahead to step 4:
If we divide 2547 by 525, we get 4 and a remainder of 447.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 2100 away from 2547, we end up with 447.
Take the next digit (1) from the dividend and append it to 447, then repeat: 4471 / 525

Let's proceed to step 5:
525 goes into 4471 8 times with a remainder of 271.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
Subtract 4200 from 4471 to get 271.
Take the next digit (4) from the dividend and append it to 271, then repeat: 2714 / 525

Advancing to step 6:
525 goes into 2714 5 times with a remainder of 89.
Write down 5 as next digit of the result. 
Result so far: 1485.0
Deduct 2625 from 2714 and we're left with 89.
Fetch the next digit (4) from the dividend, attach it to 89 and continue: 894 / 525

Moving on to step 7:
The number 525 fits into 894 1 times, leaving a remainder of 369.
Use 1 as the next digit of our solution. 
Result so far: 14851.0
The remainder is 369 after subtracting 525 from 894.
Fetch the next digit (3) from the dividend, attach it to 369 and continue: 3693 / 525

Going ahead to step 8:
525 goes into 3693 7 times with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 148517.0
Subtracting 3675 from 3693 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
The number 525 fits into 180 0 times, leaving a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 148517.0
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
If we divide 1800 by 525, we get 3 and a remainder of 225.
Write down 3 as next digit of the result. 
Result so far: 148517.03
If we subtract 1575 from 1800, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 11:
When dividing 2250 by 525, we get 4 with a remainder of 150.
Write down 4 as next digit of the result. 
Result so far: 148517.034
Deduct 2100 from 2250 and we're left 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.

Moving on to step 12:
525 can be fit into 1500 2 times, resulting in a remainder of 450.
Put 2 as the next digit of the answer. 
Result so far: 148517.0342
Subtracting 1050 from 1500 leaves us 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.

Step 13:
525 can be fit into 4500 8 times, resulting in a remainder of 300.
The next digit of our result is 8. 
Result so far: 148517.03428
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 14:
When dividing 3000 by 525, we get 5 with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 148517.034285
Subtracting 2625 from 3000 leaves us 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.

Let's proceed to step 15:
3750 divided by 525 is 7 with a remainder of 75.
The number 7 becomes the next digit in our result. 
Result so far: 148517.0342857
Subtracting 3675 from 3750 leaves us 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 16:
If we divide 750 by 525, we get 1 and a remainder of 225.
The number 1 becomes the next digit in our result. 
Result so far: 148517.03428571
If we subtract 525 from 750, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The final result is 148517.03428571 with a remainder of 2.25e-07.
