13031798 ÷ 55 
The aim is to understand the frequency of 55 in 13031798.

Let's proceed to step 1:
If we divide 1 by 55, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 55

Moving on to step 2:
The number 55 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 55

Step 3:
55 goes into 130 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 110 from 130 to get 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 55

On to step 4:
When dividing 203 by 55, we get 3 with a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 165 away from 203, we end up with 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 55

Advancing to step 5:
55 goes into 381 6 times with a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 236.0
Subtract 330 from 381 to get 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 55

Step 6:
55 goes into 517 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 2369.0
If we subtract 495 from 517, we get 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 55

Moving on to step 7:
The number 55 fits into 229 4 times, leaving a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 23694.0
Deduct 220 from 229 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 55

On to step 8:
When dividing 98 by 55, we get 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 236941.0
Subtracting 55 from 98 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
When dividing 430 by 55, we get 7 with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 236941.7
The remainder is 45 after subtracting 385 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
If we divide 450 by 55, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 236941.78
If we take 440 away from 450, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
The number 55 fits into 100 1 times, leaving a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 236941.781
If we take 55 away from 100, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 12:
When dividing 450 by 55, we get 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 236941.7818
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
If we divide 100 by 55, we get 1 and a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 236941.78181
Subtract 55 from 100 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 14:
450 divided by 55 is 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 236941.781818
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 15:
When dividing 100 by 55, we get 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 236941.7818181
Deduct 55 from 100 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 16:
55 goes into 450 8 times with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 236941.78181818
Deduct 440 from 450 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 236941.78181818 with a remainder of 1e-08.
