358394 ÷ 1 
The aim is to understand the frequency of 1 in 358394.

Let's proceed to step 1:
When dividing 3 by 1, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 3 from 3 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Going ahead to step 2:
The number 1 fits into 5 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 35.0
The remainder is 0 after subtracting 5 from 5.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Advancing to step 3:
8 divided by 1 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 358.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Let's proceed to step 4:
3 divided by 1 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3583.0
Deduct 3 from 3 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Moving on to step 5:
If we divide 9 by 1, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 35839.0
Subtract 9 from 9 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Step 6:
When dividing 4 by 1, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 358394.0
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.

Going ahead to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 358394.0
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.

On to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 358394.0
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.

After the division, we end up with 358394.0 and a remainder of 0.0.
