We're dividing 158946 by 80 
The aim is to understand the frequency of 80 in 158946.

Moving on to step 1:
80 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 80

On to step 2:
When dividing 15 by 80, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 80

Moving on to step 3:
80 goes into 158 1 times with a remainder of 78.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 80 from 158 to get 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 80

On to step 4:
80 can be fit into 789 9 times, resulting in a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 69 after subtracting 720 from 789.
Append the next digit (4) from the dividend to 69 and continue with: 694 / 80

Let's proceed to step 5:
If we divide 694 by 80, we get 8 and a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 198.0
If we subtract 640 from 694, we get 54.
Bring next digit (6) of the dividend behind the 54 and repeat the process: 546 / 80

Going ahead to step 6:
80 goes into 546 6 times with a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 1986.0
If we subtract 480 from 546, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
If we divide 660 by 80, we get 8 and a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 1986.8
Subtract 640 from 660 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 80 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 1986.82
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1986.825
Subtract 400 from 400 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 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1986.825
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 11:
80 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: 1986.825
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 quotient of the division is 1986.825, and the remainder is 0.0.
