856451 divided by 1 
The aim is to understand the frequency of 1 in 856451.

Advancing to step 1:
1 goes into 8 8 times 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.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Let's proceed to step 2:
5 divided by 1 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we subtract 5 from 5, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Advancing to step 3:
If we divide 6 by 1, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 856.0
If we subtract 6 from 6, we get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Going ahead to step 4:
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: 8564.0
Deduct 4 from 4 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Let's proceed to step 5:
1 goes into 5 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 85645.0
If we subtract 5 from 5, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Step 6:
When dividing 1 by 1, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 856451.0
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.

Going ahead to step 7:
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: 856451.0
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.

Let's proceed 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: 856451.0
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.

Our division results in 856451.0 with a remaining 0.0.
