We look at the division of 63628920 by 477 
The aim is to understand the frequency of 477 in 63628920.

Let's proceed to step 1:
477 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 477

Step 2:
The number 477 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Bring next digit (6) of the dividend behind the 63 and repeat the process: 636 / 477

Step 3:
When dividing 636 by 477, we get 1 with a remainder of 159.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 477 from 636 leaves us with 159.
Bring next digit (2) of the dividend behind the 159 and repeat the process: 1592 / 477

Step 4:
1592 divided by 477 is 3 with a remainder of 161.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 161 after subtracting 1431 from 1592.
Take the next digit (8) from the dividend and append it to 161, then repeat: 1618 / 477

Advancing to step 5:
477 can be fit into 1618 3 times, resulting in a remainder of 187.
Write down 3 as next digit of the result. 
Result so far: 133.0
Deduct 1431 from 1618 and we're left with 187.
Grab the next digit (9) from the dividend, add it to 187, then carry on: 1879 / 477

Let's proceed to step 6:
When dividing 1879 by 477, we get 3 with a remainder of 448.
Record the quotient 3 as the next digit in the result. 
Result so far: 1333.0
The remainder is 448 after subtracting 1431 from 1879.
Append the next digit (2) from the dividend to 448 and continue with: 4482 / 477

Step 7:
If we divide 4482 by 477, we get 9 and a remainder of 189.
The number 9 becomes the next digit in our result. 
Result so far: 13339.0
Subtracting 4293 from 4482 leaves us with 189.
Take the next digit (0) from the dividend and append it to 189, then repeat: 1890 / 477

Moving on to step 8:
477 can be fit into 1890 3 times, resulting in a remainder of 459.
The next digit of our result is 3. 
Result so far: 133393.0
If we subtract 1431 from 1890, we get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Step 9:
4590 divided by 477 is 9 with a remainder of 297.
The number 9 becomes the next digit in our result. 
Result so far: 133393.9
If we take 4293 away from 4590, we end up with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Let's proceed to step 10:
If we divide 2970 by 477, we get 6 and a remainder of 108.
Record the quotient 6 as the next digit in the result. 
Result so far: 133393.96
Subtract 2862 from 2970 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 11:
477 goes into 1080 2 times with a remainder of 126.
The next digit of our result is 2. 
Result so far: 133393.962
The remainder is 126 after subtracting 954 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 12:
If we divide 1260 by 477, we get 2 and a remainder of 306.
Record the quotient 2 as the next digit in the result. 
Result so far: 133393.9622
If we subtract 954 from 1260, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

After the division, we end up with 133393.9622 and a remainder of 0.00306.
