12060921 divided by 525 
The aim is to understand the frequency of 525 in 12060921.

On to step 1:
The number 525 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 525

Step 2:
525 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 525

On to step 3:
The number 525 fits into 120 0 times, leaving a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 120 after subtracting 0 from 120.
Append the next digit (6) from the dividend to 120 and continue with: 1206 / 525

On to step 4:
1206 divided by 525 is 2 with a remainder of 156.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1050 from 1206 leaves us with 156.
Include the next digit (0) from the dividend after 156, then repeat: 1560 / 525

Let's proceed to step 5:
If we divide 1560 by 525, we get 2 and a remainder of 510.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 510 after subtracting 1050 from 1560.
Take the next digit (9) from the dividend and append it to 510, then repeat: 5109 / 525

Going ahead to step 6:
The number 525 fits into 5109 9 times, leaving a remainder of 384.
Record the quotient 9 as the next digit in the result. 
Result so far: 229.0
If we subtract 4725 from 5109, we get 384.
Bring next digit (2) of the dividend behind the 384 and repeat the process: 3842 / 525

Let's proceed to step 7:
If we divide 3842 by 525, we get 7 and a remainder of 167.
Write down 7 as next digit of the result. 
Result so far: 2297.0
The remainder is 167 after subtracting 3675 from 3842.
Include the next digit (1) from the dividend after 167, then repeat: 1671 / 525

On to step 8:
525 can be fit into 1671 3 times, resulting in a remainder of 96.
Record the quotient 3 as the next digit in the result. 
Result so far: 22973.0
If we take 1575 away from 1671, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 9:
525 goes into 960 1 times with a remainder of 435.
The number 1 becomes the next digit in our result. 
Result so far: 22973.1
The remainder is 435 after subtracting 525 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

On to step 10:
When dividing 4350 by 525, we get 8 with a remainder of 150.
Use 8 as the next digit of our solution. 
Result so far: 22973.18
The remainder is 150 after subtracting 4200 from 4350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 11:
If we divide 1500 by 525, we get 2 and a remainder of 450.
Record the quotient 2 as the next digit in the result. 
Result so far: 22973.182
Deduct 1050 from 1500 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 12:
525 can be fit into 4500 8 times, resulting in a remainder of 300.
Write down 8 as next digit of the result. 
Result so far: 22973.1828
Subtracting 4200 from 4500 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 13:
If we divide 3000 by 525, we get 5 and a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 22973.18285
Subtracting 2625 from 3000 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 14:
525 goes into 3750 7 times with a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 22973.182857
Subtracting 3675 from 3750 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 15:
If we divide 750 by 525, we get 1 and a remainder of 225.
Write down 1 as next digit of the result. 
Result so far: 22973.1828571
Deduct 525 from 750 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 16:
2250 divided by 525 is 4 with a remainder of 150.
Write down 4 as next digit of the result. 
Result so far: 22973.18285714
Deduct 2100 from 2250 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

In conclusion, the division gives 22973.18285714 with a balance of 1.5e-07.
