87851269 ÷ 525 
We want to figure out the number of times 87851269 can be divided by 525.

Going ahead to step 1:
When dividing 8 by 525, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 525

Advancing to step 2:
87 divided by 525 is 0 with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Take the next digit (8) from the dividend and append it to 87, then repeat: 878 / 525

Going ahead to step 3:
If we divide 878 by 525, we get 1 and a remainder of 353.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 353 after subtracting 525 from 878.
Fetch the next digit (5) from the dividend, attach it to 353 and continue: 3535 / 525

On to step 4:
3535 divided by 525 is 6 with a remainder of 385.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 3150 from 3535 leaves us with 385.
Bring next digit (1) of the dividend behind the 385 and repeat the process: 3851 / 525

Step 5:
When dividing 3851 by 525, we get 7 with a remainder of 176.
The next digit of our result is 7. 
Result so far: 167.0
If we take 3675 away from 3851, we end up with 176.
Grab the next digit (2) from the dividend, add it to 176, then carry on: 1762 / 525

Step 6:
525 can be fit into 1762 3 times, resulting in a remainder of 187.
Record the quotient 3 as the next digit in the result. 
Result so far: 1673.0
Subtract 1575 from 1762 to get 187.
Grab the next digit (6) from the dividend, add it to 187, then carry on: 1876 / 525

Going ahead to step 7:
When dividing 1876 by 525, we get 3 with a remainder of 301.
Record the quotient 3 as the next digit in the result. 
Result so far: 16733.0
Subtracting 1575 from 1876 leaves us with 301.
Bring next digit (9) of the dividend behind the 301 and repeat the process: 3019 / 525

On to step 8:
When dividing 3019 by 525, we get 5 with a remainder of 394.
Use 5 as the next digit of our solution. 
Result so far: 167335.0
Subtract 2625 from 3019 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 9:
525 goes into 3940 7 times with a remainder of 265.
Record the quotient 7 as the next digit in the result. 
Result so far: 167335.7
Subtracting 3675 from 3940 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 10:
If we divide 2650 by 525, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 167335.75
Subtract 2625 from 2650 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
If we divide 250 by 525, we get 0 and a remainder of 250.
The next digit of our result is 0. 
Result so far: 167335.75
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 12:
525 goes into 2500 4 times with a remainder of 400.
Write down 4 as next digit of the result. 
Result so far: 167335.7504
Deduct 2100 from 2500 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 13:
525 can be fit into 4000 7 times, resulting in a remainder of 325.
Write down 7 as next digit of the result. 
Result so far: 167335.75047
Subtract 3675 from 4000 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 14:
525 goes into 3250 6 times with a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 167335.750476
If we subtract 3150 from 3250, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 15:
The number 525 fits into 1000 1 times, leaving a remainder of 475.
Write down 1 as next digit of the result. 
Result so far: 167335.7504761
Subtracting 525 from 1000 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

On to step 16:
The number 525 fits into 4750 9 times, leaving a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 167335.75047619
Subtract 4725 from 4750 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 167335.75047619 with a remaining 2.5e-08.
