We're dividing 20128801 by 481 
The aim is to understand the frequency of 481 in 20128801.

Moving on to step 1:
If we divide 2 by 481, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 481

Moving on to step 2:
The number 481 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 481

Advancing to step 3:
481 goes into 201 0 times with a remainder of 201.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 201 after subtracting 0 from 201.
Include the next digit (2) from the dividend after 201, then repeat: 2012 / 481

Moving on to step 4:
The number 481 fits into 2012 4 times, leaving a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 1924 from 2012 leaves us with 88.
Fetch the next digit (8) from the dividend, attach it to 88 and continue: 888 / 481

Step 5:
481 can be fit into 888 1 times, resulting in a remainder of 407.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 481 from 888 leaves us with 407.
Bring next digit (8) of the dividend behind the 407 and repeat the process: 4078 / 481

Moving on to step 6:
4078 divided by 481 is 8 with a remainder of 230.
Use 8 as the next digit of our solution. 
Result so far: 418.0
The remainder is 230 after subtracting 3848 from 4078.
Grab the next digit (0) from the dividend, add it to 230, then carry on: 2300 / 481

Advancing to step 7:
2300 divided by 481 is 4 with a remainder of 376.
Record the quotient 4 as the next digit in the result. 
Result so far: 4184.0
Subtract 1924 from 2300 to get 376.
Include the next digit (1) from the dividend after 376, then repeat: 3761 / 481

Let's proceed to step 8:
481 can be fit into 3761 7 times, resulting in a remainder of 394.
The number 7 becomes the next digit in our result. 
Result so far: 41847.0
Subtract 3367 from 3761 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 9:
481 goes into 3940 8 times with a remainder of 92.
The number 8 becomes the next digit in our result. 
Result so far: 41847.8
If we subtract 3848 from 3940, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 10:
When dividing 920 by 481, we get 1 with a remainder of 439.
The number 1 becomes the next digit in our result. 
Result so far: 41847.81
Subtract 481 from 920 to get 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Step 11:
481 goes into 4390 9 times with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 41847.819
Subtract 4329 from 4390 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 12:
When dividing 610 by 481, we get 1 with a remainder of 129.
Write down 1 as next digit of the result. 
Result so far: 41847.8191
Deduct 481 from 610 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 13:
1290 divided by 481 is 2 with a remainder of 328.
Record the quotient 2 as the next digit in the result. 
Result so far: 41847.81912
Subtracting 962 from 1290 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 14:
The number 481 fits into 3280 6 times, leaving a remainder of 394.
The number 6 becomes the next digit in our result. 
Result so far: 41847.819126
The remainder is 394 after subtracting 2886 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 15:
If we divide 3940 by 481, we get 8 and a remainder of 92.
Use 8 as the next digit of our solution. 
Result so far: 41847.8191268
Subtracting 3848 from 3940 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 16:
The number 481 fits into 920 1 times, leaving a remainder of 439.
Use 1 as the next digit of our solution. 
Result so far: 41847.81912681
If we subtract 481 from 920, we get 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

The final result is 41847.81912681 with a remainder of 4.39e-07.
