We're dividing 217801 by 1 
The aim is to understand the frequency of 1 in 217801.

On to step 1:
1 can be fit into 2 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 2 away from 2, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Step 2:
1 goes into 1 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 1 from 1 leaves us with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Advancing to step 3:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 217.0
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

On to step 4:
If we divide 8 by 1, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 2178.0
If we subtract 8 from 8, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Advancing to step 5:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21780.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Moving on to step 6:
1 divided by 1 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 217801.0
Subtracting 1 from 1 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.

Let's proceed to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 217801.0
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.

Step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 217801.0
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.

The quotient of the division is 217801.0, and the remainder is 0.0.
