134378 divided by 1 
The aim is to understand the frequency of 1 in 134378.

Let's proceed to step 1:
When dividing 1 by 1, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 1 from 1 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Step 2:
3 divided by 1 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 3 from 3 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Going ahead to step 3:
4 divided by 1 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 134.0
If we subtract 4 from 4, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Let's proceed to step 4:
If we divide 3 by 1, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 1343.0
If we take 3 away from 3, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Step 5:
If we divide 7 by 1, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 13437.0
If we take 7 away from 7, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Advancing to step 6:
When dividing 8 by 1, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 134378.0
If we subtract 8 from 8, 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.

Let's proceed to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 134378.0
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.

Moving on to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 134378.0
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.

Our division results in 134378.0 with a remaining 0.0.
