We're dividing 549619 by 7 
The aim is to understand the frequency of 7 in 549619.

Advancing to step 1:
5 divided by 7 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 7

Advancing to step 2:
When dividing 54 by 7, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 5 after subtracting 49 from 54.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 7

Advancing to step 3:
59 divided by 7 is 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 78.0
The remainder is 3 after subtracting 56 from 59.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 7

Let's proceed to step 4:
36 divided by 7 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 785.0
Subtract 35 from 36 to get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 7

Advancing to step 5:
11 divided by 7 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 7851.0
If we take 7 away from 11, we end up with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 7

Advancing to step 6:
7 can be fit into 49 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 78517.0
Subtract 49 from 49 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
7 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 78517.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 78517.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 78517.0 and a remainder of 0.0.
