640063 divided by 55 
The aim is to understand the frequency of 55 in 640063.

Advancing to step 1:
When dividing 6 by 55, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 55

Step 2:
55 can be fit into 64 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 9 after subtracting 55 from 64.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 55

Going ahead to step 3:
55 goes into 90 1 times with a remainder of 35.
The next digit of our result is 1. 
Result so far: 11.0
If we take 55 away from 90, we end up with 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 55

On to step 4:
When dividing 350 by 55, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Subtract 330 from 350 to get 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 55

Let's proceed to step 5:
55 can be fit into 206 3 times, resulting in a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 1163.0
The remainder is 41 after subtracting 165 from 206.
Bring next digit (3) of the dividend behind the 41 and repeat the process: 413 / 55

Let's proceed to step 6:
55 can be fit into 413 7 times, resulting in a remainder of 28.
The next digit of our result is 7. 
Result so far: 11637.0
Deduct 385 from 413 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
When dividing 280 by 55, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 11637.5
The remainder is 5 after subtracting 275 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
When dividing 50 by 55, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 11637.5
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
The number 55 fits into 500 9 times, leaving a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 11637.509
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
55 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 11637.509
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
55 can be fit into 500 9 times, resulting in a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 11637.50909
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
50 divided by 55 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 11637.50909
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
If we divide 500 by 55, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 11637.5090909
Deduct 495 from 500 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
55 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 11637.5090909
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 11637.5090909 with a remainder of 5e-08.
