We divide 12821110 by 525
The aim is to understand the frequency of 525 in 12821110.

Advancing to step 1:
1 divided by 525 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 525

Going ahead to step 2:
525 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 525

Moving on to step 3:
525 goes into 128 0 times with a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 128 leaves us with 128.
Append the next digit (2) from the dividend to 128 and continue with: 1282 / 525

Step 4:
If we divide 1282 by 525, we get 2 and a remainder of 232.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1050 from 1282 and we're left with 232.
Include the next digit (1) from the dividend after 232, then repeat: 2321 / 525

Step 5:
525 goes into 2321 4 times with a remainder of 221.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 221 after subtracting 2100 from 2321.
Bring next digit (1) of the dividend behind the 221 and repeat the process: 2211 / 525

Step 6:
525 goes into 2211 4 times with a remainder of 111.
The next digit of our result is 4. 
Result so far: 244.0
If we subtract 2100 from 2211, we get 111.
Take the next digit (1) from the dividend and append it to 111, then repeat: 1111 / 525

Let's proceed to step 7:
525 goes into 1111 2 times with a remainder of 61.
Use 2 as the next digit of our solution. 
Result so far: 2442.0
Subtract 1050 from 1111 to get 61.
Bring next digit (0) of the dividend behind the 61 and repeat the process: 610 / 525

On to step 8:
If we divide 610 by 525, we get 1 and a remainder of 85.
Write down 1 as next digit of the result. 
Result so far: 24421.0
If we subtract 525 from 610, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 9:
525 can be fit into 850 1 times, resulting in a remainder of 325.
Record the quotient 1 as the next digit in the result. 
Result so far: 24421.1
Deduct 525 from 850 and we're left 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 10:
When dividing 3250 by 525, we get 6 with a remainder of 100.
Put 6 as the next digit of the answer. 
Result so far: 24421.16
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.

On to step 11:
When dividing 1000 by 525, we get 1 with a remainder of 475.
The number 1 becomes the next digit in our result. 
Result so far: 24421.161
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.

Going ahead to step 12:
If we divide 4750 by 525, we get 9 and a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 24421.1619
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.

Moving on to step 13:
When dividing 250 by 525, we get 0 with a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 24421.1619
Subtracting 0 from 250 leaves us 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.

Going ahead to step 14:
When dividing 2500 by 525, we get 4 with a remainder of 400.
Put 4 as the next digit of the answer. 
Result so far: 24421.161904
Deduct 2100 from 2500 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 15:
525 goes into 4000 7 times with a remainder of 325.
Write down 7 as next digit of the result. 
Result so far: 24421.1619047
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.

Going ahead to step 16:
The number 525 fits into 3250 6 times, leaving a remainder of 100.
The next digit of our result is 6. 
Result so far: 24421.16190476
Deduct 3150 from 3250 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 24421.16190476, and the remainder is 1e-07.
