79990522 ÷ 180 
The aim is to understand the frequency of 180 in 79990522.

Going ahead to step 1:
7 divided by 180 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 180

Going ahead to step 2:
If we divide 79 by 180, we get 0 and a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Fetch the next digit (9) from the dividend, attach it to 79 and continue: 799 / 180

Moving on to step 3:
180 can be fit into 799 4 times, resulting in a remainder of 79.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 720 from 799 to get 79.
Include the next digit (9) from the dividend after 79, then repeat: 799 / 180

Going ahead to step 4:
When dividing 799 by 180, we get 4 with a remainder of 79.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we subtract 720 from 799, we get 79.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 180

Step 5:
If we divide 790 by 180, we get 4 and a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 444.0
If we take 720 away from 790, we end up with 70.
Append the next digit (5) from the dividend to 70 and continue with: 705 / 180

Moving on to step 6:
180 can be fit into 705 3 times, resulting in a remainder of 165.
Use 3 as the next digit of our solution. 
Result so far: 4443.0
If we take 540 away from 705, we end up with 165.
Append the next digit (2) from the dividend to 165 and continue with: 1652 / 180

Advancing to step 7:
The number 180 fits into 1652 9 times, leaving a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 44439.0
Deduct 1620 from 1652 and we're left with 32.
Append the next digit (2) from the dividend to 32 and continue with: 322 / 180

Advancing to step 8:
180 goes into 322 1 times with a remainder of 142.
The next digit of our result is 1. 
Result so far: 444391.0
If we take 180 away from 322, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 9:
If we divide 1420 by 180, we get 7 and a remainder of 160.
Use 7 as the next digit of our solution. 
Result so far: 444391.7
Subtracting 1260 from 1420 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
180 goes into 1600 8 times with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 444391.78
The remainder is 160 after subtracting 1440 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
180 can be fit into 1600 8 times, resulting in a remainder of 160.
The next digit of our result is 8. 
Result so far: 444391.788
Subtract 1440 from 1600 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

After the division, we end up with 444391.788 and a remainder of 0.016.
