We're dividing 170739 by 1 
The aim is to understand the frequency of 1 in 170739.

Let's proceed to step 1:
1 divided by 1 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 1 from 1 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Going ahead to step 2:
1 goes into 7 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 0 after subtracting 7 from 7.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Moving on to step 3:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 170.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

On to step 4:
1 goes into 7 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 1707.0
Deduct 7 from 7 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Let's proceed to step 5:
1 goes into 3 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 17073.0
The remainder is 0 after subtracting 3 from 3.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Going ahead to step 6:
The number 1 fits into 9 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 170739.0
If we take 9 away from 9, 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.

Advancing to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 170739.0
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.

Step 8:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 170739.0
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.

The quotient of the division is 170739.0, and the remainder is 0.0.
