We look at the division of 871400 by 55 
The aim is to understand the frequency of 55 in 871400.

Going ahead to step 1:
55 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 55

Going ahead to step 2:
87 divided by 55 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 55 away from 87, we end up with 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 55

On to step 3:
55 can be fit into 321 5 times, resulting in a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 275 from 321 to get 46.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 55

Step 4:
55 can be fit into 464 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
The remainder is 24 after subtracting 440 from 464.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 55

Advancing to step 5:
55 can be fit into 240 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 1584.0
Subtracting 220 from 240 leaves us with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 55

Advancing to step 6:
200 divided by 55 is 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 15843.0
Subtracting 165 from 200 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
55 can be fit into 350 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 15843.6
If we subtract 330 from 350, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
55 can be fit into 200 3 times, resulting in a remainder of 35.
The next digit of our result is 3. 
Result so far: 15843.63
If we take 165 away from 200, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
55 can be fit into 350 6 times, resulting in a remainder of 20.
The next digit of our result is 6. 
Result so far: 15843.636
Subtract 330 from 350 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
200 divided by 55 is 3 with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 15843.6363
The remainder is 35 after subtracting 165 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
When dividing 350 by 55, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 15843.63636
Deduct 330 from 350 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
When dividing 200 by 55, we get 3 with a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 15843.636363
If we subtract 165 from 200, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 13:
55 goes into 350 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 15843.6363636
If we subtract 330 from 350, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
When dividing 200 by 55, we get 3 with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 15843.63636363
The remainder is 35 after subtracting 165 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 15843.63636363, and the remainder is 3.5e-08.
