We're dividing 977503 by 1 
The aim is to understand the frequency of 1 in 977503.

Going ahead to step 1:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 0 after subtracting 9 from 9.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Moving on to step 2:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtract 7 from 7 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Step 3:
If we divide 7 by 1, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 977.0
If we take 7 away from 7, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Advancing to step 4:
When dividing 5 by 1, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 9775.0
Subtracting 5 from 5 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Advancing to step 5:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 97750.0
Subtract 0 from 0 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

On to step 6:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 977503.0
If we subtract 3 from 3, 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.

On to step 7:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 977503.0
If we subtract 0 from 0, 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.

Moving on to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 977503.0
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 977503.0 with a balance of 0.0.
