8201386 divided by 525 
Our goal is to divide 8201386 by 525.

Let's proceed to step 1:
If we divide 8 by 525, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 525

Moving on to step 2:
If we divide 82 by 525, we get 0 and a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Grab the next digit (0) from the dividend, add it to 82, then carry on: 820 / 525

On to step 3:
The number 525 fits into 820 1 times, leaving a remainder of 295.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 525 from 820 and we're left with 295.
Take the next digit (1) from the dividend and append it to 295, then repeat: 2951 / 525

On to step 4:
525 can be fit into 2951 5 times, resulting in a remainder of 326.
The next digit of our result is 5. 
Result so far: 15.0
If we take 2625 away from 2951, we end up with 326.
Append the next digit (3) from the dividend to 326 and continue with: 3263 / 525

On to step 5:
3263 divided by 525 is 6 with a remainder of 113.
The next digit of our result is 6. 
Result so far: 156.0
Subtract 3150 from 3263 to get 113.
Include the next digit (8) from the dividend after 113, then repeat: 1138 / 525

Let's proceed to step 6:
When dividing 1138 by 525, we get 2 with a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 1562.0
Subtracting 1050 from 1138 leaves us with 88.
Take the next digit (6) from the dividend and append it to 88, then repeat: 886 / 525

Let's proceed to step 7:
When dividing 886 by 525, we get 1 with a remainder of 361.
The next digit of our result is 1. 
Result so far: 15621.0
If we subtract 525 from 886, we get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Step 8:
If we divide 3610 by 525, we get 6 and a remainder of 460.
Record the quotient 6 as the next digit in the result. 
Result so far: 15621.6
The remainder is 460 after subtracting 3150 from 3610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 9:
525 goes into 4600 8 times with a remainder of 400.
Put 8 as the next digit of the answer. 
Result so far: 15621.68
Deduct 4200 from 4600 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.

Let's proceed to step 10:
525 goes into 4000 7 times with a remainder of 325.
Record the quotient 7 as the next digit in the result. 
Result so far: 15621.687
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.

Moving on to step 11:
525 goes into 3250 6 times with a remainder of 100.
The number 6 becomes the next digit in our result. 
Result so far: 15621.6876
If we take 3150 away from 3250, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
The number 525 fits into 1000 1 times, leaving a remainder of 475.
Use 1 as the next digit of our solution. 
Result so far: 15621.68761
Subtract 525 from 1000 to get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Let's proceed to step 13:
The number 525 fits into 4750 9 times, leaving a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 15621.687619
If we take 4725 away from 4750, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 14:
250 divided by 525 is 0 with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 15621.687619
Deduct 0 from 250 and we're left with 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 15:
The number 525 fits into 2500 4 times, leaving a remainder of 400.
The number 4 becomes the next digit in our result. 
Result so far: 15621.68761904
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.

The quotient of the division is 15621.68761904, and the remainder is 4e-07.
