Let's divide 375110 by 7
The aim is to understand the frequency of 7 in 375110.

Going ahead to step 1:
If we divide 3 by 7, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 7

Step 2:
37 divided by 7 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 2 after subtracting 35 from 37.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 7

Advancing to step 3:
25 divided by 7 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Deduct 21 from 25 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 7

Step 4:
7 goes into 41 5 times with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 535.0
If we take 35 away from 41, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 7

Let's proceed to step 5:
7 goes into 61 8 times with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 5358.0
Subtract 56 from 61 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 7

Advancing to step 6:
When dividing 50 by 7, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 53587.0
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.

Step 7:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 53587.1
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.

Let's proceed to step 8:
7 goes into 30 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 53587.14
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
If we divide 20 by 7, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 53587.142
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 10:
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: 53587.1428
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.

Moving on to step 11:
7 goes into 40 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 53587.14285
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.

Advancing to step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 53587.142857
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.

On to step 13:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 53587.1428571
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.

Advancing to step 14:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 53587.14285714
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.

Our division results in 53587.14285714 with a remaining 2e-09.
