We look at the division of 76231 by 1 
The aim is to understand the frequency of 1 in 76231.

Moving on to step 1:
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: 7.0
If we subtract 7 from 7, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Advancing to step 2:
1 goes into 6 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 76.0
If we subtract 6 from 6, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Moving on to step 3:
If we divide 2 by 1, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 762.0
Subtract 2 from 2 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Moving on to step 4:
1 goes into 3 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 7623.0
Subtracting 3 from 3 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Going ahead to step 5:
1 divided by 1 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 76231.0
Subtract 1 from 1 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 6:
0 divided by 1 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 76231.0
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 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: 76231.0
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 76231.0 with a balance of 0.0.
