357368 ÷ 7 
The aim is to understand the frequency of 7 in 357368.

Moving on to step 1:
7 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 7

Going ahead to step 2:
When dividing 35 by 7, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
If we take 35 away from 35, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 7

Advancing to step 3:
7 goes into 7 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtract 7 from 7 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 7

Moving on to step 4:
7 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 510.0
If we subtract 0 from 3, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 7

Let's proceed to step 5:
When dividing 36 by 7, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5105.0
Deduct 35 from 36 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 7

On to step 6:
7 goes into 18 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 51052.0
Subtracting 14 from 18 leaves us 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.

Let's proceed to step 7:
If we divide 40 by 7, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 51052.5
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.

Step 8:
When dividing 50 by 7, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 51052.57
Subtract 49 from 50 to 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.

Advancing to step 9:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 51052.571
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.

Let's proceed to step 10:
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: 51052.5714
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.

Step 11:
If we divide 20 by 7, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 51052.57142
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.

Advancing to step 12:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 51052.571428
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.

Advancing to step 13:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 51052.5714285
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.

Let's proceed to step 14:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 51052.57142857
Subtracting 49 from 50 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.

The final result is 51052.57142857 with a remainder of 1e-09.
