78196019 ÷ 525 
We want to figure out the number of times 78196019 can be divided by 525.

On to step 1:
7 divided by 525 is 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.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 525

Advancing to step 2:
When dividing 78 by 525, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 525

Let's proceed to step 3:
781 divided by 525 is 1 with a remainder of 256.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 256 after subtracting 525 from 781.
Include the next digit (9) from the dividend after 256, then repeat: 2569 / 525

On to step 4:
2569 divided by 525 is 4 with a remainder of 469.
The next digit of our result is 4. 
Result so far: 14.0
If we take 2100 away from 2569, we end up with 469.
Grab the next digit (6) from the dividend, add it to 469, then carry on: 4696 / 525

On to step 5:
525 goes into 4696 8 times with a remainder of 496.
The next digit of our result is 8. 
Result so far: 148.0
Subtracting 4200 from 4696 leaves us with 496.
Take the next digit (0) from the dividend and append it to 496, then repeat: 4960 / 525

Advancing to step 6:
If we divide 4960 by 525, we get 9 and a remainder of 235.
Put 9 as the next digit of the answer. 
Result so far: 1489.0
Subtracting 4725 from 4960 leaves us with 235.
Fetch the next digit (1) from the dividend, attach it to 235 and continue: 2351 / 525

Step 7:
525 goes into 2351 4 times with a remainder of 251.
Record the quotient 4 as the next digit in the result. 
Result so far: 14894.0
If we take 2100 away from 2351, we end up with 251.
Include the next digit (9) from the dividend after 251, then repeat: 2519 / 525

Going ahead to step 8:
The number 525 fits into 2519 4 times, leaving a remainder of 419.
The number 4 becomes the next digit in our result. 
Result so far: 148944.0
If we take 2100 away from 2519, we end up with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Step 9:
When dividing 4190 by 525, we get 7 with a remainder of 515.
Write down 7 as next digit of the result. 
Result so far: 148944.7
Subtract 3675 from 4190 to get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

On to step 10:
5150 divided by 525 is 9 with a remainder of 425.
The next digit of our result is 9. 
Result so far: 148944.79
Deduct 4725 from 5150 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 11:
When dividing 4250 by 525, we get 8 with a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 148944.798
If we take 4200 away from 4250, we end up with 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 12:
500 divided by 525 is 0 with a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 148944.798
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 13:
When dividing 5000 by 525, we get 9 with a remainder of 275.
Use 9 as the next digit of our solution. 
Result so far: 148944.79809
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.

Advancing to step 14:
2750 divided by 525 is 5 with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 148944.798095
Subtracting 2625 from 2750 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 15:
525 goes into 1250 2 times with a remainder of 200.
Put 2 as the next digit of the answer. 
Result so far: 148944.7980952
Subtract 1050 from 1250 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 16:
525 goes into 2000 3 times with a remainder of 425.
The next digit of our result is 3. 
Result so far: 148944.79809523
Deduct 1575 from 2000 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

The final outcome is 148944.79809523, with a leftover of 4.25e-07.
