We divide 193673 by 1
The aim is to understand the frequency of 1 in 193673.

On to step 1:
If we divide 1 by 1, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 1 away from 1, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Advancing to step 2:
1 goes into 9 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 9 from 9 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Step 3:
If we divide 3 by 1, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 193.0
Deduct 3 from 3 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Going ahead to step 4:
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: 1936.0
If we take 6 away from 6, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Going ahead to step 5:
When dividing 7 by 1, we get 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 19367.0
If we take 7 away from 7, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Advancing to step 6:
If we divide 3 by 1, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 193673.0
If we subtract 3 from 3, 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.

Advancing to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 193673.0
Subtract 0 from 0 to 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.

On to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 193673.0
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.

Our division results in 193673.0 with a remaining 0.0.
