We divide 443142 by 1
The aim is to understand the frequency of 1 in 443142.

On to step 1:
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: 4.0
If we subtract 4 from 4, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Advancing to step 2:
When dividing 4 by 1, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we take 4 away from 4, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Moving on to step 3:
The number 1 fits into 3 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 443.0
Subtract 3 from 3 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Advancing to step 4:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 4431.0
Subtracting 1 from 1 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Step 5:
When dividing 4 by 1, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 44314.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Let's proceed to step 6:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 443142.0
Subtracting 2 from 2 leaves us 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:
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: 443142.0
Subtracting 0 from 0 leaves us 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 8:
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: 443142.0
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.

The quotient of the division is 443142.0, and the remainder is 0.0.
