80143318 divided by 580 
The aim is to understand the frequency of 580 in 80143318.

Going ahead to step 1:
When dividing 8 by 580, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 580

Going ahead to step 2:
If we divide 80 by 580, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 580

Moving on to step 3:
580 can be fit into 801 1 times, resulting in a remainder of 221.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 580 away from 801, we end up with 221.
Grab the next digit (4) from the dividend, add it to 221, then carry on: 2214 / 580

Moving on to step 4:
The number 580 fits into 2214 3 times, leaving a remainder of 474.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 1740 from 2214 and we're left with 474.
Take the next digit (3) from the dividend and append it to 474, then repeat: 4743 / 580

Moving on to step 5:
580 can be fit into 4743 8 times, resulting in a remainder of 103.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Subtract 4640 from 4743 to get 103.
Take the next digit (3) from the dividend and append it to 103, then repeat: 1033 / 580

On to step 6:
580 goes into 1033 1 times with a remainder of 453.
The next digit of our result is 1. 
Result so far: 1381.0
Subtracting 580 from 1033 leaves us with 453.
Append the next digit (1) from the dividend to 453 and continue with: 4531 / 580

Advancing to step 7:
4531 divided by 580 is 7 with a remainder of 471.
Use 7 as the next digit of our solution. 
Result so far: 13817.0
Subtract 4060 from 4531 to get 471.
Take the next digit (8) from the dividend and append it to 471, then repeat: 4718 / 580

On to step 8:
When dividing 4718 by 580, we get 8 with a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 138178.0
If we subtract 4640 from 4718, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 9:
The number 580 fits into 780 1 times, leaving a remainder of 200.
Put 1 as the next digit of the answer. 
Result so far: 138178.1
Subtract 580 from 780 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 10:
580 goes into 2000 3 times with a remainder of 260.
Record the quotient 3 as the next digit in the result. 
Result so far: 138178.13
If we subtract 1740 from 2000, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 11:
580 goes into 2600 4 times with a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 138178.134
Subtracting 2320 from 2600 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 12:
The number 580 fits into 2800 4 times, leaving a remainder of 480.
Write down 4 as next digit of the result. 
Result so far: 138178.1344
Deduct 2320 from 2800 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Our division results in 138178.1344 with a remaining 0.0048.
