We divide 75144 by 7
The aim is to understand the frequency of 7 in 75144.

Going ahead to step 1:
When dividing 7 by 7, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 7 from 7 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 7

Let's proceed to step 2:
7 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 7

On to step 3:
The number 7 fits into 51 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 107.0
If we subtract 49 from 51, we get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 7

Advancing to step 4:
24 divided by 7 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 1073.0
Subtracting 21 from 24 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 7

Moving on to step 5:
7 can be fit into 34 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 10734.0
If we take 28 away from 34, 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.

Moving on to step 6:
If we divide 60 by 7, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 10734.8
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 7:
40 divided by 7 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 10734.85
If we take 35 away from 40, we end up 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:
7 goes into 50 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 10734.857
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 9:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 10734.8571
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.

Moving on to step 10:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 10734.85714
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.

Going ahead to step 11:
When dividing 20 by 7, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 10734.857142
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.

Step 12:
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: 10734.8571428
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.

Advancing to step 13:
40 divided by 7 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 10734.85714285
Deduct 35 from 40 and we're left 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.

The final result is 10734.85714285 with a remainder of 5e-09.
