Let's divide 705664 by 1
The aim is to understand the frequency of 1 in 705664.

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

On to step 2:
When dividing 0 by 1, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Subtract 0 from 0 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Moving on to step 3:
1 goes into 5 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 705.0
The remainder is 0 after subtracting 5 from 5.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

On to step 4:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 7056.0
Subtract 6 from 6 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Going ahead to step 5:
1 goes into 6 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 70566.0
Deduct 6 from 6 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Moving on to step 6:
4 divided by 1 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 705664.0
Subtract 4 from 4 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 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: 705664.0
Subtracting 0 from 0 leaves us 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.
The number 0 becomes the next digit in our result. 
Result so far: 705664.0
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.

Our division results in 705664.0 with a remaining 0.0.
