We divide 801901 by 1
The aim is to understand the frequency of 1 in 801901.

On to step 1:
8 divided by 1 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 8 from 8 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Advancing to step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 80.0
If we subtract 0 from 0, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Advancing to step 3:
If we divide 1 by 1, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 801.0
If we take 1 away from 1, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Going ahead to step 4:
1 goes into 9 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 8019.0
The remainder is 0 after subtracting 9 from 9.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Advancing to step 5:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 80190.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Let's proceed to step 6:
If we divide 1 by 1, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 801901.0
Subtract 1 from 1 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.

Let's proceed to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 801901.0
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.

On to step 8:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 801901.0
If we subtract 0 from 0, 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.

In conclusion, the division gives 801901.0 with a balance of 0.0.
