We divide 659799 by 1
The aim is to understand the frequency of 1 in 659799.

Going ahead to step 1:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 6 from 6 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Let's proceed to step 2:
When dividing 5 by 1, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we subtract 5 from 5, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Step 3:
9 divided by 1 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 659.0
Deduct 9 from 9 and we're left with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

On to step 4:
1 goes into 7 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 6597.0
Deduct 7 from 7 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Advancing to step 5:
1 goes into 9 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 65979.0
The remainder is 0 after subtracting 9 from 9.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Moving on to step 6:
When dividing 9 by 1, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 659799.0
Deduct 9 from 9 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.

Advancing to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 659799.0
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.

Moving on to step 8:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 659799.0
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.

The final outcome is 659799.0, with a leftover of 0.0.
