We look at the division of 87818042 by 55 
The aim is to understand the frequency of 55 in 87818042.

Let's proceed to step 1:
The number 55 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 55

Step 2:
55 can be fit into 87 1 times, resulting in a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 55 from 87, we get 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 55

Let's proceed to step 3:
328 divided by 55 is 5 with a remainder of 53.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 275 from 328 and we're left with 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 55

Advancing to step 4:
If we divide 531 by 55, we get 9 and a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Subtracting 495 from 531 leaves us with 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 55

Let's proceed to step 5:
When dividing 368 by 55, we get 6 with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 1596.0
The remainder is 38 after subtracting 330 from 368.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 55

Let's proceed to step 6:
55 goes into 380 6 times with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 15966.0
Deduct 330 from 380 and we're left with 50.
Take the next digit (4) from the dividend and append it to 50, then repeat: 504 / 55

Advancing to step 7:
If we divide 504 by 55, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 159669.0
If we take 495 away from 504, we end up with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 55

Moving on to step 8:
92 divided by 55 is 1 with a remainder of 37.
The next digit of our result is 1. 
Result so far: 1596691.0
Subtract 55 from 92 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
When dividing 370 by 55, we get 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 1596691.6
If we subtract 330 from 370, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 1596691.67
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
55 goes into 150 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 1596691.672
Subtract 110 from 150 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
When dividing 400 by 55, we get 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 1596691.6727
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
If we divide 150 by 55, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 1596691.67272
If we subtract 110 from 150, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
When dividing 400 by 55, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 1596691.672727
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 15:
The number 55 fits into 150 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 1596691.6727272
If we subtract 110 from 150, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 16:
55 goes into 400 7 times with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 1596691.67272727
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 1596691.67272727, and the remainder is 1.5e-08.
