784932 ÷ 7 
The aim is to understand the frequency of 7 in 784932.

Step 1:
If we divide 7 by 7, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 7 from 7 leaves us with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 7

On to step 2:
The number 7 fits into 8 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 7 from 8 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 7

Let's proceed to step 3:
14 divided by 7 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 112.0
The remainder is 0 after subtracting 14 from 14.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 7

Going ahead to step 4:
When dividing 9 by 7, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1121.0
If we take 7 away from 9, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 7

Advancing to step 5:
If we divide 23 by 7, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 11213.0
Deduct 21 from 23 and we're left with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 7

Step 6:
When dividing 22 by 7, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 112133.0
If we subtract 21 from 22, we get 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 7:
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: 112133.1
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.

Going ahead to step 8:
If we divide 30 by 7, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 112133.14
Subtracting 28 from 30 leaves us 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.

On to step 9:
When dividing 20 by 7, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 112133.142
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.

Step 10:
When dividing 60 by 7, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 112133.1428
The remainder is 4 after subtracting 56 from 60.
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 11:
40 divided by 7 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 112133.14285
If we subtract 35 from 40, we 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 12:
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: 112133.142857
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.

Moving on to step 13:
When dividing 10 by 7, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 112133.1428571
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.

On to step 14:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 112133.14285714
Subtracting 28 from 30 leaves us 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.

Our division results in 112133.14285714 with a remaining 2e-09.
