Let's divide 668973 by 55
The aim is to understand the frequency of 55 in 668973.

Moving on to step 1:
55 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 55

On to step 2:
55 goes into 66 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 55 from 66, we get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 55

Advancing to step 3:
The number 55 fits into 118 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 110 from 118 leaves us with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 55

Moving on to step 4:
When dividing 89 by 55, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 121.0
Deduct 55 from 89 and we're left with 34.
Take the next digit (7) from the dividend and append it to 34, then repeat: 347 / 55

Advancing to step 5:
347 divided by 55 is 6 with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 1216.0
If we take 330 away from 347, we end up with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 55

Moving on to step 6:
55 can be fit into 173 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 12163.0
Subtracting 165 from 173 leaves us 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.

Moving on to step 7:
55 can be fit into 80 1 times, resulting in a remainder of 25.
The next digit of our result is 1. 
Result so far: 12163.1
Deduct 55 from 80 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 8:
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: 12163.14
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.

Advancing to step 9:
When dividing 300 by 55, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 12163.145
If we subtract 275 from 300, we 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.

On to step 10:
250 divided by 55 is 4 with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 12163.1454
If we subtract 220 from 250, we 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.

Going ahead to step 11:
If we divide 300 by 55, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 12163.14545
If we take 275 away from 300, 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.

Moving on to step 12:
The number 55 fits into 250 4 times, leaving a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 12163.145454
The remainder is 30 after subtracting 220 from 250.
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 13:
55 can be fit into 300 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 12163.1454545
If we subtract 275 from 300, we 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.

Moving on to step 14:
55 goes into 250 4 times with a remainder of 30.
The next digit of our result is 4. 
Result so far: 12163.14545454
The remainder is 30 after subtracting 220 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 12163.14545454, with a leftover of 3e-08.
