55259 ÷ 7 
The aim is to understand the frequency of 7 in 55259.

Going ahead to step 1:
7 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 7

Advancing to step 2:
7 can be fit into 55 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 49 away from 55, we end up with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 7

Advancing to step 3:
When dividing 62 by 7, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Subtract 56 from 62 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 7

Advancing to step 4:
When dividing 65 by 7, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 789.0
Subtracting 63 from 65 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 7

On to step 5:
29 divided by 7 is 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 7894.0
Subtracting 28 from 29 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
If we divide 10 by 7, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 7894.1
If we take 7 away from 10, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
7 goes into 30 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 7894.14
Subtracting 28 from 30 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
7 goes into 20 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 7894.142
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
60 divided by 7 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 7894.1428
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 7, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 7894.14285
If we take 35 away from 40, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
When dividing 50 by 7, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7894.142857
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
If we divide 10 by 7, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 7894.1428571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 13:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 7894.14285714
Subtracting 28 from 30 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 7894.14285714 with a remainder of 2e-09.
