126783 divided by 1 
The aim is to understand the frequency of 1 in 126783.

Moving on to step 1:
The number 1 fits into 1 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 1 from 1 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Step 2:
1 goes into 2 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 0 after subtracting 2 from 2.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

On to step 3:
6 divided by 1 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 126.0
Deduct 6 from 6 and we're left with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 1

Advancing to step 4:
1 goes into 7 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 1267.0
Deduct 7 from 7 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Going ahead to step 5:
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: 12678.0
Subtracting 8 from 8 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Step 6:
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: 126783.0
The remainder is 0 after subtracting 3 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 126783.0
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.

Let's proceed 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: 126783.0
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 126783.0 with a balance of 0.0.
