We look at the division of 53780163 by 55 
The aim is to understand the frequency of 55 in 53780163.

Step 1:
55 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 55

Advancing to step 2:
If we divide 53 by 55, we get 0 and a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 55

On to step 3:
If we divide 537 by 55, we get 9 and a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 495 from 537 leaves us with 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 55

Going ahead to step 4:
The number 55 fits into 428 7 times, leaving a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Subtract 385 from 428 to get 43.
Append the next digit (0) from the dividend to 43 and continue with: 430 / 55

Going ahead to step 5:
55 goes into 430 7 times with a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 977.0
If we subtract 385 from 430, we get 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 55

Advancing to step 6:
When dividing 451 by 55, we get 8 with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 9778.0
The remainder is 11 after subtracting 440 from 451.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 55

Step 7:
If we divide 116 by 55, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 97782.0
Subtracting 110 from 116 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 55

Let's proceed to step 8:
55 can be fit into 63 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 977821.0
If we take 55 away from 63, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
When dividing 80 by 55, we get 1 with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 977821.1
If we take 55 away from 80, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
55 goes into 250 4 times with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 977821.14
Subtracting 220 from 250 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
55 goes into 300 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 977821.145
The remainder is 25 after subtracting 275 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
55 can be fit into 250 4 times, resulting in a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 977821.1454
Subtract 220 from 250 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
If we divide 300 by 55, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 977821.14545
Deduct 275 from 300 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 14:
55 goes into 250 4 times with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 977821.145454
Subtracting 220 from 250 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 15:
300 divided by 55 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 977821.1454545
Subtract 275 from 300 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 16:
If we divide 250 by 55, we get 4 and a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 977821.14545454
Deduct 220 from 250 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 977821.14545454 and a remainder of 3e-08.
