We're dividing 507044 by 1 
The aim is to understand the frequency of 1 in 507044.

Going ahead to step 1:
5 divided by 1 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 5 from 5 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Moving on to step 2:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 0 to get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 1

On to step 3:
When dividing 7 by 1, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 507.0
If we subtract 7 from 7, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Let's proceed to step 4:
0 divided by 1 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5070.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Going ahead to step 5:
When dividing 4 by 1, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 50704.0
If we subtract 4 from 4, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Advancing to step 6:
If we divide 4 by 1, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 507044.0
If we subtract 4 from 4, we 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.

Advancing to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 507044.0
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:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 507044.0
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.

After the division, we end up with 507044.0 and a remainder of 0.0.
