39984483 ÷ 1 
The aim is to understand the frequency of 1 in 39984483.

Step 1:
3 divided by 1 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 3 from 3 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Moving on to step 2:
1 goes into 9 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
The remainder is 0 after subtracting 9 from 9.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Moving on to step 3:
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: 399.0
Deduct 9 from 9 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Moving on to step 4:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 3998.0
The remainder is 0 after subtracting 8 from 8.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Advancing to step 5:
4 divided by 1 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 39984.0
Deduct 4 from 4 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Advancing to step 6:
4 divided by 1 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 399844.0
The remainder is 0 after subtracting 4 from 4.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Step 7:
1 goes into 8 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 3998448.0
The remainder is 0 after subtracting 8 from 8.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Step 8:
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: 39984483.0
If we subtract 3 from 3, we 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.

Going ahead to step 9:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39984483.0
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.

Advancing to step 10:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39984483.0
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.

The final outcome is 39984483.0, with a leftover of 0.0.
