146412 ÷ 80 
The aim is to understand the frequency of 80 in 146412.

Advancing 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
If we subtract 0 from 1, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 80

Moving on to step 2:
80 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 80

Let's proceed to step 3:
If we divide 146 by 80, we get 1 and a remainder of 66.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 80 from 146, we get 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 80

Step 4:
80 goes into 664 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 24 after subtracting 640 from 664.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 80

On to step 5:
80 goes into 241 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 183.0
Subtract 240 from 241 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 80

On to step 6:
80 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 1830.0
Subtract 0 from 12 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
When dividing 120 by 80, we get 1 with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1830.1
Deduct 80 from 120 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.

Let's proceed to step 8:
If we divide 400 by 80, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 1830.15
Subtracting 400 from 400 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.

On to step 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1830.15
If we subtract 0 from 0, 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.

Step 10:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1830.15
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 1830.15, and the remainder is 0.0.
