We divide 73188095 by 525
The aim is to understand the frequency of 525 in 73188095.

On to step 1:
7 divided by 525 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 525

Advancing to step 2:
525 goes into 73 0 times with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 525

Step 3:
731 divided by 525 is 1 with a remainder of 206.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 525 away from 731, we end up with 206.
Bring next digit (8) of the dividend behind the 206 and repeat the process: 2068 / 525

Moving on to step 4:
The number 525 fits into 2068 3 times, leaving a remainder of 493.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 1575 from 2068, we get 493.
Include the next digit (8) from the dividend after 493, then repeat: 4938 / 525

Advancing to step 5:
4938 divided by 525 is 9 with a remainder of 213.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
Subtracting 4725 from 4938 leaves us with 213.
Append the next digit (0) from the dividend to 213 and continue with: 2130 / 525

Step 6:
When dividing 2130 by 525, we get 4 with a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 1394.0
If we subtract 2100 from 2130, we get 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 525

Step 7:
When dividing 309 by 525, we get 0 with a remainder of 309.
Put 0 as the next digit of the answer. 
Result so far: 13940.0
Subtract 0 from 309 to get 309.
Include the next digit (5) from the dividend after 309, then repeat: 3095 / 525

Let's proceed to step 8:
The number 525 fits into 3095 5 times, leaving a remainder of 470.
Use 5 as the next digit of our solution. 
Result so far: 139405.0
Subtract 2625 from 3095 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 9:
4700 divided by 525 is 8 with a remainder of 500.
Record the quotient 8 as the next digit in the result. 
Result so far: 139405.8
If we take 4200 away from 4700, we end up 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.

Going ahead to step 10:
525 can be fit into 5000 9 times, resulting in a remainder of 275.
Record the quotient 9 as the next digit in the result. 
Result so far: 139405.89
If we subtract 4725 from 5000, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 11:
525 goes into 2750 5 times with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 139405.895
If we subtract 2625 from 2750, we get 125.
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 12:
525 can be fit into 1250 2 times, resulting in a remainder of 200.
Put 2 as the next digit of the answer. 
Result so far: 139405.8952
Subtracting 1050 from 1250 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 13:
525 goes into 2000 3 times with a remainder of 425.
The number 3 becomes the next digit in our result. 
Result so far: 139405.89523
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 14:
If we divide 4250 by 525, we get 8 and a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 139405.895238
If we subtract 4200 from 4250, 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.

Step 15:
525 can be fit into 500 0 times, resulting in a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 139405.895238
Deduct 0 from 500 and we're left 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.

On to step 16:
5000 divided by 525 is 9 with a remainder of 275.
Put 9 as the next digit of the answer. 
Result so far: 139405.89523809
Subtract 4725 from 5000 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

The final outcome is 139405.89523809, with a leftover of 2.75e-07.
