We divide 336583 by 7
The aim is to understand the frequency of 7 in 336583.

Let's proceed to step 1:
3 divided by 7 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 7

Let's proceed to step 2:
When dividing 33 by 7, we get 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 28 from 33 to get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 7

Going ahead to step 3:
7 goes into 56 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtracting 56 from 56 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 7

Advancing to step 4:
When dividing 5 by 7, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 480.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 7

Let's proceed to step 5:
When dividing 58 by 7, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 4808.0
If we subtract 56 from 58, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 7

Let's proceed to step 6:
7 can be fit into 23 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 48083.0
Deduct 21 from 23 and we're left 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 7:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 48083.2
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 48083.28
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.

Moving on to step 9:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 48083.285
The remainder is 5 after subtracting 35 from 40.
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:
When dividing 50 by 7, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 48083.2857
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.

On to step 11:
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: 48083.28571
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.

Moving on to step 12:
30 divided by 7 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 48083.285714
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:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 48083.2857142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
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: 48083.28571428
Deduct 56 from 60 and we're left 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.

After the division, we end up with 48083.28571428 and a remainder of 4e-09.
