14589290 ÷ 525 
The aim is to understand the frequency of 525 in 14589290.

Going ahead to step 1:
525 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 525

Moving on to step 2:
The number 525 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 525

Moving on to step 3:
When dividing 145 by 525, we get 0 with a remainder of 145.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 145 leaves us with 145.
Bring next digit (8) of the dividend behind the 145 and repeat the process: 1458 / 525

On to step 4:
525 can be fit into 1458 2 times, resulting in a remainder of 408.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1050 from 1458 leaves us with 408.
Grab the next digit (9) from the dividend, add it to 408, then carry on: 4089 / 525

On to step 5:
The number 525 fits into 4089 7 times, leaving a remainder of 414.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtract 3675 from 4089 to get 414.
Take the next digit (2) from the dividend and append it to 414, then repeat: 4142 / 525

On to step 6:
When dividing 4142 by 525, we get 7 with a remainder of 467.
Use 7 as the next digit of our solution. 
Result so far: 277.0
Subtract 3675 from 4142 to get 467.
Fetch the next digit (9) from the dividend, attach it to 467 and continue: 4679 / 525

Moving on to step 7:
525 can be fit into 4679 8 times, resulting in a remainder of 479.
Put 8 as the next digit of the answer. 
Result so far: 2778.0
If we take 4200 away from 4679, we end up with 479.
Append the next digit (0) from the dividend to 479 and continue with: 4790 / 525

Going ahead to step 8:
If we divide 4790 by 525, we get 9 and a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 27789.0
Subtract 4725 from 4790 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 9:
The number 525 fits into 650 1 times, leaving a remainder of 125.
Record the quotient 1 as the next digit in the result. 
Result so far: 27789.1
Subtract 525 from 650 to 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.

On to step 10:
1250 divided by 525 is 2 with a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 27789.12
If we take 1050 away from 1250, we end up 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.

Going ahead to step 11:
If we divide 2000 by 525, we get 3 and a remainder of 425.
The next digit of our result is 3. 
Result so far: 27789.123
The remainder is 425 after subtracting 1575 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 12:
525 can be fit into 4250 8 times, resulting in a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 27789.1238
Subtract 4200 from 4250 to 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 13:
525 can be fit into 500 0 times, resulting in a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 27789.1238
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 14:
When dividing 5000 by 525, we get 9 with a remainder of 275.
Put 9 as the next digit of the answer. 
Result so far: 27789.123809
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.

Let's proceed to step 15:
525 can be fit into 2750 5 times, resulting in a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 27789.1238095
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.

Moving on to step 16:
1250 divided by 525 is 2 with a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 27789.12380952
If we subtract 1050 from 1250, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 27789.12380952, with a leftover of 2e-07.
