356017 ÷ 1 
The aim is to understand the frequency of 1 in 356017.

On to step 1:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 0 after subtracting 3 from 3.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Moving on to step 2:
If we divide 5 by 1, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 5 from 5 and we're left with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Advancing to step 3:
6 divided by 1 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 356.0
Subtracting 6 from 6 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Step 4:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3560.0
The remainder is 0 after subtracting 0 from 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.
Use 1 as the next digit of our solution. 
Result so far: 35601.0
Subtract 1 from 1 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Step 6:
1 goes into 7 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 356017.0
Deduct 7 from 7 and we're left 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 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: 356017.0
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.

Let's proceed to step 8:
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: 356017.0
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.

The final result is 356017.0 with a remainder of 0.0.
