We divide 34434942 by 1
The aim is to understand the frequency of 1 in 34434942.

Step 1:
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: 3.0
If we take 3 away from 3, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Moving on to step 2:
The number 1 fits into 4 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 4 from 4 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

On to step 3:
4 divided by 1 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 344.0
Deduct 4 from 4 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Advancing to step 4:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3443.0
If we take 3 away from 3, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Moving on to step 5:
When dividing 4 by 1, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 34434.0
Subtracting 4 from 4 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Going ahead to step 6:
1 can be fit into 9 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 344349.0
Subtracting 9 from 9 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

On to step 7:
The number 1 fits into 4 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 3443494.0
Subtracting 4 from 4 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Moving on to step 8:
1 goes into 2 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 34434942.0
The remainder is 0 after subtracting 2 from 2.
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 9:
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: 34434942.0
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.

Let's proceed to step 10:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 34434942.0
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.

Our division results in 34434942.0 with a remaining 0.0.
