789805 ÷ 1 
The aim is to understand the frequency of 1 in 789805.

On to step 1:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 7 from 7 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Going ahead to step 2:
The number 1 fits into 8 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 78.0
If we take 8 away from 8, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

On to step 3:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 789.0
Deduct 9 from 9 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Let's proceed to step 4:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 7898.0
If we subtract 8 from 8, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Let's proceed to step 5:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 78980.0
If we take 0 away from 0, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Going ahead to step 6:
1 goes into 5 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 789805.0
Deduct 5 from 5 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 789805.0
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:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 789805.0
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.

After the division, we end up with 789805.0 and a remainder of 0.0.
