838423 divided by 1 
The aim is to understand the frequency of 1 in 838423.

Moving on to step 1:
1 goes into 8 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 0 after subtracting 8 from 8.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Advancing to step 2:
When dividing 3 by 1, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 83.0
Subtracting 3 from 3 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Moving on to step 3:
1 goes into 8 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 838.0
If we subtract 8 from 8, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Going ahead to step 4:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 8384.0
If we take 4 away from 4, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

On to step 5:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 83842.0
Subtracting 2 from 2 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Advancing to step 6:
1 goes into 3 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 838423.0
If we take 3 away from 3, 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.

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: 838423.0
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.

Step 8:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 838423.0
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.

In conclusion, the division gives 838423.0 with a balance of 0.0.
