89727285 ÷ 580 
The aim is to understand the frequency of 580 in 89727285.

Advancing to step 1:
The number 580 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 580

Let's proceed to step 2:
580 can be fit into 89 0 times, resulting in a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Take the next digit (7) from the dividend and append it to 89, then repeat: 897 / 580

On to step 3:
The number 580 fits into 897 1 times, leaving a remainder of 317.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 580 from 897 leaves us with 317.
Bring next digit (2) of the dividend behind the 317 and repeat the process: 3172 / 580

Going ahead to step 4:
580 goes into 3172 5 times with a remainder of 272.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2900 away from 3172, we end up with 272.
Grab the next digit (7) from the dividend, add it to 272, then carry on: 2727 / 580

Advancing to step 5:
580 can be fit into 2727 4 times, resulting in a remainder of 407.
Use 4 as the next digit of our solution. 
Result so far: 154.0
If we subtract 2320 from 2727, we get 407.
Grab the next digit (2) from the dividend, add it to 407, then carry on: 4072 / 580

Moving on to step 6:
When dividing 4072 by 580, we get 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 1547.0
Subtract 4060 from 4072 to get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 580

Moving on to step 7:
128 divided by 580 is 0 with a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 15470.0
Deduct 0 from 128 and we're left with 128.
Bring next digit (5) of the dividend behind the 128 and repeat the process: 1285 / 580

Advancing to step 8:
The number 580 fits into 1285 2 times, leaving a remainder of 125.
The number 2 becomes the next digit in our result. 
Result so far: 154702.0
Subtracting 1160 from 1285 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 9:
The number 580 fits into 1250 2 times, leaving a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 154702.2
The remainder is 90 after subtracting 1160 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
580 goes into 900 1 times with a remainder of 320.
The next digit of our result is 1. 
Result so far: 154702.21
If we take 580 away from 900, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 11:
3200 divided by 580 is 5 with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 154702.215
Subtract 2900 from 3200 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 12:
580 can be fit into 3000 5 times, resulting in a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 154702.2155
If we take 2900 away from 3000, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 154702.2155 with a remainder of 0.001.
