We divide 30660163 by 525
The aim is to understand the frequency of 525 in 30660163.

Going ahead to step 1:
If we divide 3 by 525, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 525

On to step 2:
The number 525 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 525

Step 3:
If we divide 306 by 525, we get 0 and a remainder of 306.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 306 to get 306.
Take the next digit (6) from the dividend and append it to 306, then repeat: 3066 / 525

Moving on to step 4:
525 can be fit into 3066 5 times, resulting in a remainder of 441.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 2625 from 3066 and we're left with 441.
Grab the next digit (0) from the dividend, add it to 441, then carry on: 4410 / 525

Going ahead to step 5:
The number 525 fits into 4410 8 times, leaving a remainder of 210.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
The remainder is 210 after subtracting 4200 from 4410.
Append the next digit (1) from the dividend to 210 and continue with: 2101 / 525

Going ahead to step 6:
525 can be fit into 2101 4 times, resulting in a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 584.0
The remainder is 1 after subtracting 2100 from 2101.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 525

Let's proceed to step 7:
When dividing 16 by 525, we get 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 5840.0
Subtracting 0 from 16 leaves us with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 525

Moving on to step 8:
163 divided by 525 is 0 with a remainder of 163.
Record the quotient 0 as the next digit in the result. 
Result so far: 58400.0
The remainder is 163 after subtracting 0 from 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 9:
The number 525 fits into 1630 3 times, leaving a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 58400.3
Deduct 1575 from 1630 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 10:
525 can be fit into 550 1 times, resulting in a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 58400.31
If we subtract 525 from 550, we 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.

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: 58400.31
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.

Moving on to step 12:
The number 525 fits into 2500 4 times, leaving a remainder of 400.
Write down 4 as next digit of the result. 
Result so far: 58400.3104
Subtract 2100 from 2500 to get 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 13:
If we divide 4000 by 525, we get 7 and a remainder of 325.
Use 7 as the next digit of our solution. 
Result so far: 58400.31047
If we take 3675 away from 4000, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 14:
525 can be fit into 3250 6 times, resulting in a remainder of 100.
Record the quotient 6 as the next digit in the result. 
Result so far: 58400.310476
Subtract 3150 from 3250 to 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.

Advancing to step 15:
1000 divided by 525 is 1 with a remainder of 475.
The number 1 becomes the next digit in our result. 
Result so far: 58400.3104761
If we subtract 525 from 1000, we 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.

Moving on to step 16:
525 goes into 4750 9 times with a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 58400.31047619
The remainder is 25 after subtracting 4725 from 4750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 58400.31047619, with a leftover of 2.5e-08.
