Let's divide 91589 by 1
The aim is to understand the frequency of 1 in 91589.

Step 1:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 9 from 9 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Let's proceed to step 2:
1 can be fit into 1 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 91.0
Subtract 1 from 1 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

On to step 3:
5 divided by 1 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 915.0
Subtracting 5 from 5 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Step 4:
1 goes into 8 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 9158.0
If we take 8 away from 8, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Moving on to step 5:
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: 91589.0
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.

On to step 6:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 91589.0
The remainder is 0 after subtracting 0 from 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 7:
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: 91589.0
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 final outcome is 91589.0, with a leftover of 0.0.
