788375 ÷ 7 
The aim is to understand the frequency of 7 in 788375.

Going ahead to step 1:
7 goes into 7 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 7 from 7.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 7

On to step 2:
7 can be fit into 8 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 7 away from 8, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 7

On to step 3:
18 divided by 7 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we subtract 14 from 18, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 7

Going ahead to step 4:
7 goes into 43 6 times with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 1126.0
Subtract 42 from 43 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 7

Advancing to step 5:
7 goes into 17 2 times with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 11262.0
Subtracting 14 from 17 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 7

Step 6:
7 can be fit into 35 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 112625.0
Deduct 35 from 35 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 112625.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
7 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 112625.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 112625.0, and the remainder is 0.0.
