845016 divided by 7 
The aim is to understand the frequency of 7 in 845016.

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 subtract 7 from 8, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 7

On to step 2:
14 divided by 7 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 14 from 14 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 7

Moving on to step 3:
5 divided by 7 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
If we take 0 away from 5, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 7

Let's proceed to step 4:
7 goes into 50 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 1207.0
If we subtract 49 from 50, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 7

Let's proceed to step 5:
7 goes into 11 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 12071.0
Subtract 7 from 11 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 7

Step 6:
When dividing 46 by 7, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 120716.0
Deduct 42 from 46 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.

Let's proceed to step 7:
When dividing 40 by 7, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 120716.5
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.

On to step 8:
50 divided by 7 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 120716.57
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.

Moving on to step 9:
If we divide 10 by 7, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 120716.571
If we take 7 away from 10, we end up 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.

Step 10:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 120716.5714
Deduct 28 from 30 and we're left 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.

Let's proceed to step 11:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 120716.57142
Subtract 14 from 20 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
7 goes into 60 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 120716.571428
Subtract 56 from 60 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.

Advancing to step 13:
40 divided by 7 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 120716.5714285
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.

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: 120716.57142857
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.

In conclusion, the division gives 120716.57142857 with a balance of 1e-09.
