Let's divide 83093966 by 525
The aim is to understand the frequency of 525 in 83093966.

Step 1:
525 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 525

On to step 2:
The number 525 fits into 83 0 times, leaving a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Append the next digit (0) from the dividend to 83 and continue with: 830 / 525

Advancing to step 3:
830 divided by 525 is 1 with a remainder of 305.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 525 from 830 leaves us with 305.
Fetch the next digit (9) from the dividend, attach it to 305 and continue: 3059 / 525

On to step 4:
525 can be fit into 3059 5 times, resulting in a remainder of 434.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 2625 from 3059 to get 434.
Fetch the next digit (3) from the dividend, attach it to 434 and continue: 4343 / 525

Advancing to step 5:
When dividing 4343 by 525, we get 8 with a remainder of 143.
Write down 8 as next digit of the result. 
Result so far: 158.0
Subtract 4200 from 4343 to get 143.
Take the next digit (9) from the dividend and append it to 143, then repeat: 1439 / 525

On to step 6:
The number 525 fits into 1439 2 times, leaving a remainder of 389.
The next digit of our result is 2. 
Result so far: 1582.0
If we subtract 1050 from 1439, we get 389.
Take the next digit (6) from the dividend and append it to 389, then repeat: 3896 / 525

Step 7:
The number 525 fits into 3896 7 times, leaving a remainder of 221.
The number 7 becomes the next digit in our result. 
Result so far: 15827.0
Subtract 3675 from 3896 to get 221.
Bring next digit (6) of the dividend behind the 221 and repeat the process: 2216 / 525

Going ahead to step 8:
525 can be fit into 2216 4 times, resulting in a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 158274.0
If we subtract 2100 from 2216, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 9:
The number 525 fits into 1160 2 times, leaving a remainder of 110.
Write down 2 as next digit of the result. 
Result so far: 158274.2
Deduct 1050 from 1160 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
When dividing 1100 by 525, we get 2 with a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 158274.22
If we subtract 1050 from 1100, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 158274.22 and a remainder of 0.05.
