We're dividing 355554 by 7 
The aim is to understand the frequency of 7 in 355554.

Moving on to step 1:
7 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 7

Let's proceed to step 2:
7 goes into 35 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 35 from 35 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 7

Step 3:
7 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we subtract 0 from 5, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 7

Advancing to step 4:
When dividing 55 by 7, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 507.0
Deduct 49 from 55 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 7

Going ahead to step 5:
7 goes into 65 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 5079.0
The remainder is 2 after subtracting 63 from 65.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 7

Moving on to step 6:
If we divide 24 by 7, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 50793.0
Deduct 21 from 24 and we're left 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.

Let's proceed to step 7:
30 divided by 7 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 50793.4
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.

On to step 8:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 50793.42
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.

Moving on to step 9:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 50793.428
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
7 goes into 40 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 50793.4285
Subtracting 35 from 40 leaves us 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.

Moving on to step 11:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 50793.42857
Deduct 49 from 50 and we're left 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.

Advancing to step 12:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 50793.428571
Deduct 7 from 10 and we're left 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.

Step 13:
When dividing 30 by 7, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 50793.4285714
Subtract 28 from 30 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.

Moving on to step 14:
If we divide 20 by 7, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 50793.42857142
Subtract 14 from 20 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 50793.42857142, with a leftover of 6e-09.
