168625 divided by 1 
The aim is to understand the frequency of 1 in 168625.

Advancing to step 1:
If we divide 1 by 1, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 1 away from 1, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Moving on to step 2:
When dividing 6 by 1, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 0 after subtracting 6 from 6.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Step 3:
8 divided by 1 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 168.0
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Going ahead to step 4:
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: 1686.0
The remainder is 0 after subtracting 6 from 6.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Advancing to step 5:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 16862.0
Deduct 2 from 2 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Advancing to step 6:
When dividing 5 by 1, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 168625.0
If we take 5 away from 5, 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 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 168625.0
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.

Advancing 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: 168625.0
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.

After the division, we end up with 168625.0 and a remainder of 0.0.
