Let's divide 846774 by 7
The aim is to understand the frequency of 7 in 846774.

Advancing to step 1:
7 goes into 8 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 7

Going ahead to step 2:
14 divided by 7 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 14 away from 14, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 7

On to step 3:
7 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 7

Step 4:
When dividing 67 by 7, we get 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 1209.0
Deduct 63 from 67 and we're left with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 7

On to step 5:
If we divide 47 by 7, we get 6 and a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 12096.0
The remainder is 5 after subtracting 42 from 47.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 7

Moving on to step 6:
When dividing 54 by 7, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 120967.0
Subtracting 49 from 54 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.

Step 7:
7 goes into 50 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 120967.7
If we take 49 away from 50, we end up 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.

Advancing to step 8:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 120967.71
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.

Moving on to step 9:
30 divided by 7 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 120967.714
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.

Let's proceed to step 10:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 120967.7142
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 11:
7 goes into 60 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 120967.71428
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.

Step 12:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 120967.714285
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.

Advancing to step 13:
When dividing 50 by 7, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 120967.7142857
Deduct 49 from 50 and we're left 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.

Moving on to step 14:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 120967.71428571
If we subtract 7 from 10, we 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.

In conclusion, the division gives 120967.71428571 with a balance of 3e-09.
