We look at the division of 56142590 by 180 
The aim is to understand the frequency of 180 in 56142590.

On to step 1:
If we divide 5 by 180, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 180

Moving on to step 2:
If we divide 56 by 180, we get 0 and a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Fetch the next digit (1) from the dividend, attach it to 56 and continue: 561 / 180

Going ahead to step 3:
180 goes into 561 3 times with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 540 from 561 to get 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 180

Going ahead to step 4:
180 goes into 214 1 times with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtracting 180 from 214 leaves us with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 180

Going ahead to step 5:
When dividing 342 by 180, we get 1 with a remainder of 162.
Use 1 as the next digit of our solution. 
Result so far: 311.0
If we take 180 away from 342, we end up with 162.
Take the next digit (5) from the dividend and append it to 162, then repeat: 1625 / 180

Let's proceed to step 6:
When dividing 1625 by 180, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 3119.0
Subtracting 1620 from 1625 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 180

Moving on to step 7:
If we divide 59 by 180, we get 0 and a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 31190.0
If we take 0 away from 59, we end up with 59.
Grab the next digit (0) from the dividend, add it to 59, then carry on: 590 / 180

On to step 8:
590 divided by 180 is 3 with a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 311903.0
If we take 540 away from 590, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
500 divided by 180 is 2 with a remainder of 140.
Write down 2 as next digit of the result. 
Result so far: 311903.2
Deduct 360 from 500 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
When dividing 1400 by 180, we get 7 with a remainder of 140.
The next digit of our result is 7. 
Result so far: 311903.27
Subtracting 1260 from 1400 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 11:
If we divide 1400 by 180, we get 7 and a remainder of 140.
The next digit of our result is 7. 
Result so far: 311903.277
Deduct 1260 from 1400 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 311903.277 with a remainder of 0.014.
