Let's divide 337371 by 7
The aim is to understand the frequency of 7 in 337371.

Step 1:
The number 7 fits into 3 0 times, leaving 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.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 7

On to step 2:
7 goes into 33 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 28 from 33 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 7

On to step 3:
If we divide 57 by 7, we get 8 and a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Deduct 56 from 57 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 7

Moving on to step 4:
7 goes into 13 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 481.0
If we take 7 away from 13, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 7

Going ahead to step 5:
The number 7 fits into 67 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 4819.0
Subtracting 63 from 67 leaves us with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 7

Let's proceed to step 6:
7 goes into 41 5 times with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 48195.0
The remainder is 6 after subtracting 35 from 41.
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 7:
When dividing 60 by 7, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 48195.8
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.

Let's proceed to step 8:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 48195.85
If we subtract 35 from 40, we 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.

Let's proceed to step 9:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 48195.857
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 48195.8571
Subtracting 7 from 10 leaves us 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 11:
If we divide 30 by 7, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 48195.85714
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.

Let's proceed to step 12:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 48195.857142
If we subtract 14 from 20, we 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.

Advancing to step 13:
When dividing 60 by 7, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 48195.8571428
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.

Advancing to step 14:
40 divided by 7 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 48195.85714285
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.

After the division, we end up with 48195.85714285 and a remainder of 5e-09.
