We look at the division of 741715 by 1 
The aim is to understand the frequency of 1 in 741715.

Step 1:
7 divided by 1 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 7 away from 7, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Let's proceed to step 2:
1 goes into 4 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtracting 4 from 4 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Step 3:
If we divide 1 by 1, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 741.0
Deduct 1 from 1 and we're left with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Moving on to step 4:
When dividing 7 by 1, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7417.0
If we take 7 away from 7, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Advancing to step 5:
1 goes into 1 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 74171.0
Deduct 1 from 1 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Let's proceed to step 6:
1 goes into 5 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 741715.0
If we take 5 away from 5, 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.

Step 7:
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: 741715.0
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.

Step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 741715.0
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.

Our division results in 741715.0 with a remaining 0.0.
