We're dividing 48638644 by 814 
The aim is to understand the frequency of 814 in 48638644.

Let's proceed to step 1:
When dividing 4 by 814, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 814

Going ahead to step 2:
When dividing 48 by 814, we get 0 with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 814

Moving on to step 3:
814 goes into 486 0 times with a remainder of 486.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 486 to get 486.
Bring next digit (3) of the dividend behind the 486 and repeat the process: 4863 / 814

Going ahead to step 4:
814 can be fit into 4863 5 times, resulting in a remainder of 793.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 4070 from 4863 to get 793.
Include the next digit (8) from the dividend after 793, then repeat: 7938 / 814

Step 5:
If we divide 7938 by 814, we get 9 and a remainder of 612.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
The remainder is 612 after subtracting 7326 from 7938.
Take the next digit (6) from the dividend and append it to 612, then repeat: 6126 / 814

Advancing to step 6:
The number 814 fits into 6126 7 times, leaving a remainder of 428.
The number 7 becomes the next digit in our result. 
Result so far: 597.0
Subtracting 5698 from 6126 leaves us with 428.
Take the next digit (4) from the dividend and append it to 428, then repeat: 4284 / 814

Step 7:
When dividing 4284 by 814, we get 5 with a remainder of 214.
The number 5 becomes the next digit in our result. 
Result so far: 5975.0
Deduct 4070 from 4284 and we're left with 214.
Include the next digit (4) from the dividend after 214, then repeat: 2144 / 814

On to step 8:
If we divide 2144 by 814, we get 2 and a remainder of 516.
The next digit of our result is 2. 
Result so far: 59752.0
Subtracting 1628 from 2144 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 9:
If we divide 5160 by 814, we get 6 and a remainder of 276.
The next digit of our result is 6. 
Result so far: 59752.6
Subtracting 4884 from 5160 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 10:
If we divide 2760 by 814, we get 3 and a remainder of 318.
Write down 3 as next digit of the result. 
Result so far: 59752.63
The remainder is 318 after subtracting 2442 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 11:
814 goes into 3180 3 times with a remainder of 738.
The next digit of our result is 3. 
Result so far: 59752.633
If we take 2442 away from 3180, we end up with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Our division results in 59752.633 with a remaining 0.0738.
