381253 divided by 1 
The aim is to understand the frequency of 1 in 381253.

On to step 1:
3 divided by 1 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 3 from 3 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

On to step 2:
If we divide 8 by 1, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we take 8 away from 8, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Step 3:
1 goes into 1 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 381.0
Deduct 1 from 1 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Let's proceed to step 4:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 3812.0
Deduct 2 from 2 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Step 5:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 38125.0
If we take 5 away from 5, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Step 6:
1 goes into 3 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 381253.0
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.

Let's proceed to step 7:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 381253.0
The remainder is 0 after subtracting 0 from 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 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 381253.0
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.

In conclusion, the division gives 381253.0 with a balance of 0.0.
