801651 divided by 1 
The aim is to understand the frequency of 1 in 801651.

Moving on to step 1:
The number 1 fits into 8 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 8 from 8 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Advancing to step 2:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtract 0 from 0 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Moving on to step 3:
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: 801.0
The remainder is 0 after subtracting 1 from 1.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Let's proceed to step 4:
1 goes into 6 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 8016.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Advancing to step 5:
When dividing 5 by 1, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 80165.0
Deduct 5 from 5 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

On to step 6:
1 divided by 1 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 801651.0
The remainder is 0 after subtracting 1 from 1.
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 7:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 801651.0
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.

Advancing to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 801651.0
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 801651.0 with a balance of 0.0.
