795421 ÷ 7 
The aim is to understand the frequency of 7 in 795421.

Let's proceed to step 1:
If we divide 7 by 7, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 7 from 7, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 7

Step 2:
If we divide 9 by 7, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 7 from 9 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 7

Let's proceed to step 3:
The number 7 fits into 25 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 113.0
If we subtract 21 from 25, we get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 7

Advancing to step 4:
The number 7 fits into 44 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 1136.0
Subtract 42 from 44 to get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 7

Advancing to step 5:
7 goes into 22 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 11363.0
The remainder is 1 after subtracting 21 from 22.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 7

Going ahead to step 6:
If we divide 11 by 7, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 113631.0
Subtract 7 from 11 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 7:
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: 113631.5
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.

On to step 8:
50 divided by 7 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 113631.57
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.

Step 9:
If we divide 10 by 7, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 113631.571
Subtract 7 from 10 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
7 goes into 30 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 113631.5714
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.

Moving on to step 11:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 113631.57142
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.

On to step 12:
7 goes into 60 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 113631.571428
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.

Moving on to step 13:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 113631.5714285
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.

Step 14:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 113631.57142857
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 113631.57142857, and the remainder is 1e-09.
