We're dividing 745434 by 1 
The aim is to understand the frequency of 1 in 745434.

Going ahead to step 1:
1 goes into 7 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 0 after subtracting 7 from 7.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Moving on to step 2:
If we divide 4 by 1, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Deduct 4 from 4 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Step 3:
5 divided by 1 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 745.0
Subtracting 5 from 5 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Going ahead to step 4:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 7454.0
If we take 4 away from 4, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Advancing to step 5:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 74543.0
Subtracting 3 from 3 leaves us with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

On to step 6:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 745434.0
The remainder is 0 after subtracting 4 from 4.
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: 745434.0
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.

Advancing to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 745434.0
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 745434.0 with a remaining 0.0.
