We divide 436393 by 1
The aim is to understand the frequency of 1 in 436393.

Advancing to step 1:
4 divided by 1 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 4 from 4 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Advancing to step 2:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 3 from 3 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Going ahead to step 3:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 436.0
Subtracting 6 from 6 leaves us with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Going ahead to step 4:
1 goes into 3 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 4363.0
The remainder is 0 after subtracting 3 from 3.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Moving on to step 5:
When dividing 9 by 1, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 43639.0
Subtract 9 from 9 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

On to step 6:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 436393.0
Deduct 3 from 3 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.

Moving on to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 436393.0
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.

Step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 436393.0
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.

Our division results in 436393.0 with a remaining 0.0.
