We're dividing 25327809 by 481 
The aim is to understand the frequency of 481 in 25327809.

On to step 1:
The number 481 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 481

Step 2:
When dividing 25 by 481, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 481

Going ahead to step 3:
The number 481 fits into 253 0 times, leaving a remainder of 253.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 253 after subtracting 0 from 253.
Grab the next digit (2) from the dividend, add it to 253, then carry on: 2532 / 481

Step 4:
The number 481 fits into 2532 5 times, leaving a remainder of 127.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 2405 from 2532 and we're left with 127.
Bring next digit (7) of the dividend behind the 127 and repeat the process: 1277 / 481

Advancing to step 5:
481 can be fit into 1277 2 times, resulting in a remainder of 315.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
The remainder is 315 after subtracting 962 from 1277.
Bring next digit (8) of the dividend behind the 315 and repeat the process: 3158 / 481

Moving on to step 6:
481 goes into 3158 6 times with a remainder of 272.
The number 6 becomes the next digit in our result. 
Result so far: 526.0
The remainder is 272 after subtracting 2886 from 3158.
Include the next digit (0) from the dividend after 272, then repeat: 2720 / 481

Step 7:
481 goes into 2720 5 times with a remainder of 315.
Record the quotient 5 as the next digit in the result. 
Result so far: 5265.0
If we subtract 2405 from 2720, we get 315.
Include the next digit (9) from the dividend after 315, then repeat: 3159 / 481

On to step 8:
481 goes into 3159 6 times with a remainder of 273.
Record the quotient 6 as the next digit in the result. 
Result so far: 52656.0
Subtracting 2886 from 3159 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Going ahead to step 9:
2730 divided by 481 is 5 with a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 52656.5
If we take 2405 away from 2730, 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.

Let's proceed to step 10:
If we divide 3250 by 481, we get 6 and a remainder of 364.
The next digit of our result is 6. 
Result so far: 52656.56
Deduct 2886 from 3250 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 11:
When dividing 3640 by 481, we get 7 with a remainder of 273.
Record the quotient 7 as the next digit in the result. 
Result so far: 52656.567
If we take 3367 away from 3640, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 12:
If we divide 2730 by 481, we get 5 and a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 52656.5675
If we subtract 2405 from 2730, we get 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 13:
The number 481 fits into 3250 6 times, leaving a remainder of 364.
The next digit of our result is 6. 
Result so far: 52656.56756
Subtract 2886 from 3250 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 14:
481 can be fit into 3640 7 times, resulting in a remainder of 273.
The next digit of our result is 7. 
Result so far: 52656.567567
The remainder is 273 after subtracting 3367 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Going ahead to step 15:
481 can be fit into 2730 5 times, resulting in a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 52656.5675675
Subtracting 2405 from 2730 leaves us 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.

On to step 16:
481 goes into 3250 6 times with a remainder of 364.
Write down 6 as next digit of the result. 
Result so far: 52656.56756756
Subtract 2886 from 3250 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

After the division, we end up with 52656.56756756 and a remainder of 3.64e-07.
