780110 divided by 1 
The aim is to understand the frequency of 1 in 780110.

Step 1:
When dividing 7 by 1, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 7 from 7 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Moving on to step 2:
1 goes into 8 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 78.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Let's proceed to step 3:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 780.0
Subtract 0 from 0 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Advancing to step 4:
If we divide 1 by 1, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 7801.0
If we take 1 away from 1, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

On to step 5:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 78011.0
The remainder is 0 after subtracting 1 from 1.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Advancing to step 6:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 780110.0
Subtracting 0 from 0 leaves us 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.

Advancing to step 7:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 780110.0
Deduct 0 from 0 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.

On to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 780110.0
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 780110.0 and a remainder of 0.0.
