Let's divide 724890 by 55
The aim is to understand the frequency of 55 in 724890.

Going ahead to step 1:
The number 55 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 55

Moving on to step 2:
If we divide 72 by 55, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 55 from 72 and we're left with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 55

On to step 3:
55 can be fit into 174 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 165 from 174 leaves us with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 55

Step 4:
55 can be fit into 98 1 times, resulting in a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 131.0
If we take 55 away from 98, we end up with 43.
Grab the next digit (9) from the dividend, add it to 43, then carry on: 439 / 55

Moving on to step 5:
If we divide 439 by 55, we get 7 and a remainder of 54.
The next digit of our result is 7. 
Result so far: 1317.0
If we subtract 385 from 439, we get 54.
Take the next digit (0) from the dividend and append it to 54, then repeat: 540 / 55

Step 6:
55 goes into 540 9 times with a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 13179.0
Deduct 495 from 540 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.

Advancing to step 7:
The number 55 fits into 450 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 13179.8
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.

Going ahead to step 8:
If we divide 100 by 55, we get 1 and a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 13179.81
The remainder is 45 after subtracting 55 from 100.
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 9:
55 can be fit into 450 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 13179.818
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.

Advancing to step 10:
100 divided by 55 is 1 with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 13179.8181
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 11:
450 divided by 55 is 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 13179.81818
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.

Let's proceed to step 12:
The number 55 fits into 100 1 times, leaving a remainder of 45.
The next digit of our result is 1. 
Result so far: 13179.818181
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.

On to step 13:
When dividing 450 by 55, we get 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 13179.8181818
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 14:
The number 55 fits into 100 1 times, leaving a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 13179.81818181
The remainder is 45 after subtracting 55 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 13179.81818181 with a remainder of 4.5e-08.
