We look at the division of 357633 by 1 
The aim is to understand the frequency of 1 in 357633.

Moving on to step 1:
1 goes into 3 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 3 from 3 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Step 2:
1 goes into 5 5 times with 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 (7) from the dividend to 0 and continue with: 7 / 1

Going ahead to step 3:
If we divide 7 by 1, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 357.0
Deduct 7 from 7 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Advancing to step 4:
1 goes into 6 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 3576.0
If we take 6 away from 6, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Step 5:
If we divide 3 by 1, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 35763.0
Deduct 3 from 3 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Let's proceed to step 6:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 357633.0
The remainder is 0 after subtracting 3 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 357633.0
Deduct 0 from 0 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.

Advancing to step 8:
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: 357633.0
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.

The quotient of the division is 357633.0, and the remainder is 0.0.
