167973 divided by 1 
The aim is to understand the frequency of 1 in 167973.

Step 1:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 1 from 1 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Moving on to step 2:
6 divided by 1 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 6 away from 6, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

On to step 3:
1 goes into 7 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 167.0
The remainder is 0 after subtracting 7 from 7.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Let's proceed to step 4:
The number 1 fits into 9 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 1679.0
If we subtract 9 from 9, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Step 5:
1 goes into 7 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 16797.0
If we take 7 away from 7, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Step 6:
3 divided by 1 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 167973.0
If we take 3 away from 3, 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.

On to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 167973.0
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.

Going ahead to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 167973.0
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 167973.0, with a leftover of 0.0.
