We look at the division of 881040 by 1 
The aim is to understand the frequency of 1 in 881040.

On to step 1:
8 divided by 1 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 8 from 8, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Moving on to step 2:
1 goes into 8 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 88.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

On to step 3:
1 can be fit into 1 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 881.0
Deduct 1 from 1 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Step 4:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8810.0
The remainder is 0 after subtracting 0 from 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Advancing to step 5:
4 divided by 1 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 88104.0
If we subtract 4 from 4, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Advancing to step 6:
When dividing 0 by 1, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 881040.0
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.

Going ahead to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 881040.0
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.

Going ahead to step 8:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 881040.0
If we take 0 away from 0, 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.

The final outcome is 881040.0, with a leftover of 0.0.
