We look at the division of 942781 by 7 
The aim is to understand the frequency of 7 in 942781.

Step 1:
7 goes into 9 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 7 from 9 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 7

Let's proceed to step 2:
The number 7 fits into 24 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 21 from 24, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 7

Let's proceed to step 3:
If we divide 32 by 7, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 134.0
If we take 28 away from 32, we end up with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 7

Going ahead to step 4:
7 goes into 47 6 times with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 1346.0
Subtract 42 from 47 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 7

Let's proceed to step 5:
58 divided by 7 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 13468.0
The remainder is 2 after subtracting 56 from 58.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 7

Advancing to step 6:
When dividing 21 by 7, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 134683.0
If we subtract 21 from 21, we 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.

Advancing to step 7:
0 divided by 7 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 134683.0
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:
The number 7 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 134683.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 134683.0 with a balance of 0.0.
