180980 ÷ 79 
The aim is to understand the frequency of 79 in 180980.

Step 1:
79 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 79

Let's proceed to step 2:
18 divided by 79 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 79

Step 3:
If we divide 180 by 79, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 158 from 180, we get 22.
Take the next digit (9) from the dividend and append it to 22, then repeat: 229 / 79

Step 4:
79 goes into 229 2 times with a remainder of 71.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 158 from 229, we get 71.
Grab the next digit (8) from the dividend, add it to 71, then carry on: 718 / 79

On to step 5:
79 goes into 718 9 times with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 229.0
If we subtract 711 from 718, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 79

Moving on to step 6:
79 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 2290.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 7:
When dividing 700 by 79, we get 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 2290.8
The remainder is 68 after subtracting 632 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
79 goes into 680 8 times with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 2290.88
Subtract 632 from 680 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 2290.88 with a remainder of 0.048.
