623606 divided by 1 
The aim is to understand the frequency of 1 in 623606.

Going ahead to step 1:
6 divided by 1 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 0 after subtracting 6 from 6.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Moving on to step 2:
If we divide 2 by 1, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 62.0
If we subtract 2 from 2, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Going ahead to step 3:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 623.0
The remainder is 0 after subtracting 3 from 3.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Going ahead to step 4:
1 goes into 6 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6236.0
Subtract 6 from 6 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Going ahead to step 5:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 62360.0
Subtract 0 from 0 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Going ahead to step 6:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 623606.0
If we subtract 6 from 6, 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.

Let's proceed to step 7:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 623606.0
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.

Moving on to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 623606.0
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.

The final outcome is 623606.0, with a leftover of 0.0.
