555997 divided by 1 
The aim is to understand the frequency of 1 in 555997.

Advancing to step 1:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 0 after subtracting 5 from 5.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Step 2:
If we divide 5 by 1, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 55.0
If we take 5 away from 5, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Advancing to step 3:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 555.0
Deduct 5 from 5 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Going ahead to step 4:
The number 1 fits into 9 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 5559.0
Subtract 9 from 9 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Step 5:
If we divide 9 by 1, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 55599.0
If we subtract 9 from 9, we get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Step 6:
When dividing 7 by 1, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 555997.0
The remainder is 0 after subtracting 7 from 7.
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: 555997.0
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.

Going ahead 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: 555997.0
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.

After the division, we end up with 555997.0 and a remainder of 0.0.
