554535 divided by 7 
The aim is to understand the frequency of 7 in 554535.

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
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 7

Advancing to step 2:
55 divided by 7 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 6 after subtracting 49 from 55.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 7

Going ahead to step 3:
7 can be fit into 64 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 79.0
If we take 63 away from 64, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 7

Moving on to step 4:
When dividing 15 by 7, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 792.0
The remainder is 1 after subtracting 14 from 15.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 7

Step 5:
If we divide 13 by 7, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 7921.0
If we subtract 7 from 13, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 7

Let's proceed to step 6:
7 can be fit into 65 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 79219.0
Subtract 63 from 65 to get 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 7:
When dividing 20 by 7, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 79219.2
Subtracting 14 from 20 leaves us 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.

Advancing to step 8:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 79219.28
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
40 divided by 7 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 79219.285
Subtract 35 from 40 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 79219.2857
If we subtract 49 from 50, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 79219.28571
If we subtract 7 from 10, we get 3.
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 12:
7 goes into 30 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 79219.285714
If we take 28 away from 30, we end up 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.

Step 13:
When dividing 20 by 7, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 79219.2857142
If we take 14 away from 20, we end up 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 14:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 79219.28571428
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 79219.28571428 with a remainder of 4e-09.
