We divide 55440160 by 525
The aim is to understand the frequency of 525 in 55440160.

Advancing to step 1:
If we divide 5 by 525, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 525

Step 2:
525 can be fit into 55 0 times, resulting in a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 525

Step 3:
When dividing 554 by 525, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
If we take 525 away from 554, we end up with 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 525

On to step 4:
294 divided by 525 is 0 with a remainder of 294.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 294 to get 294.
Bring next digit (0) of the dividend behind the 294 and repeat the process: 2940 / 525

On to step 5:
When dividing 2940 by 525, we get 5 with a remainder of 315.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we take 2625 away from 2940, we end up with 315.
Grab the next digit (1) from the dividend, add it to 315, then carry on: 3151 / 525

Going ahead to step 6:
525 goes into 3151 6 times with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 1056.0
If we subtract 3150 from 3151, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 525

Moving on to step 7:
The number 525 fits into 16 0 times, leaving a remainder of 16.
The next digit of our result is 0. 
Result so far: 10560.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 525

On to step 8:
If we divide 160 by 525, we get 0 and a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 105600.0
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 9:
525 goes into 1600 3 times with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 105600.3
Subtract 1575 from 1600 to 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.

Going ahead to step 10:
525 goes into 250 0 times with a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 105600.3
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 11:
When dividing 2500 by 525, we get 4 with a remainder of 400.
The next digit of our result is 4. 
Result so far: 105600.304
If we subtract 2100 from 2500, we 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 12:
The number 525 fits into 4000 7 times, leaving a remainder of 325.
Use 7 as the next digit of our solution. 
Result so far: 105600.3047
The remainder is 325 after subtracting 3675 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 13:
When dividing 3250 by 525, we get 6 with a remainder of 100.
Record the quotient 6 as the next digit in the result. 
Result so far: 105600.30476
The remainder is 100 after subtracting 3150 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 14:
525 goes into 1000 1 times with a remainder of 475.
Use 1 as the next digit of our solution. 
Result so far: 105600.304761
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.

Step 15:
The number 525 fits into 4750 9 times, leaving a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 105600.3047619
Deduct 4725 from 4750 and we're left 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.

Step 16:
If we divide 250 by 525, we get 0 and a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 105600.3047619
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final outcome is 105600.3047619, with a leftover of 2.5e-07.
