Let's divide 82943780 by 525
The aim is to understand the frequency of 525 in 82943780.

On 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
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 525

On to step 2:
If we divide 82 by 525, we get 0 and a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Fetch the next digit (9) from the dividend, attach it to 82 and continue: 829 / 525

Step 3:
829 divided by 525 is 1 with a remainder of 304.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 525 from 829 and we're left with 304.
Fetch the next digit (4) from the dividend, attach it to 304 and continue: 3044 / 525

Let's proceed to step 4:
525 goes into 3044 5 times with a remainder of 419.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2625 away from 3044, we end up with 419.
Fetch the next digit (3) from the dividend, attach it to 419 and continue: 4193 / 525

On to step 5:
525 can be fit into 4193 7 times, resulting in a remainder of 518.
Write down 7 as next digit of the result. 
Result so far: 157.0
If we subtract 3675 from 4193, we get 518.
Fetch the next digit (7) from the dividend, attach it to 518 and continue: 5187 / 525

Let's proceed to step 6:
525 goes into 5187 9 times with a remainder of 462.
Put 9 as the next digit of the answer. 
Result so far: 1579.0
Subtract 4725 from 5187 to get 462.
Include the next digit (8) from the dividend after 462, then repeat: 4628 / 525

Let's proceed to step 7:
525 goes into 4628 8 times with a remainder of 428.
Record the quotient 8 as the next digit in the result. 
Result so far: 15798.0
Deduct 4200 from 4628 and we're left with 428.
Include the next digit (0) from the dividend after 428, then repeat: 4280 / 525

Let's proceed to step 8:
The number 525 fits into 4280 8 times, leaving a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 157988.0
Subtract 4200 from 4280 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
525 goes into 800 1 times with a remainder of 275.
Write down 1 as next digit of the result. 
Result so far: 157988.1
Deduct 525 from 800 and we're left 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.

Let's proceed to step 10:
The number 525 fits into 2750 5 times, leaving a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 157988.15
The remainder is 125 after subtracting 2625 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 11:
The number 525 fits into 1250 2 times, leaving a remainder of 200.
Use 2 as the next digit of our solution. 
Result so far: 157988.152
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.

Step 12:
When dividing 2000 by 525, we get 3 with a remainder of 425.
Write down 3 as next digit of the result. 
Result so far: 157988.1523
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.

Going ahead to step 13:
525 goes into 4250 8 times with a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 157988.15238
Subtracting 4200 from 4250 leaves us 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 14:
The number 525 fits into 500 0 times, leaving a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 157988.15238
Subtracting 0 from 500 leaves us 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:
When dividing 5000 by 525, we get 9 with a remainder of 275.
Write down 9 as next digit of the result. 
Result so far: 157988.1523809
If we take 4725 away from 5000, we end up 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.

Step 16:
525 goes into 2750 5 times with a remainder of 125.
The next digit of our result is 5. 
Result so far: 157988.15238095
Deduct 2625 from 2750 and we're left 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.

After the division, we end up with 157988.15238095 and a remainder of 1.25e-07.
