We're dividing 72770286 by 585 
The aim is to understand the frequency of 585 in 72770286.

On to step 1:
585 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 585

Let's proceed to step 2:
When dividing 72 by 585, we get 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Grab the next digit (7) from the dividend, add it to 72, then carry on: 727 / 585

Going ahead to step 3:
The number 585 fits into 727 1 times, leaving a remainder of 142.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 585 from 727 leaves us with 142.
Bring next digit (7) of the dividend behind the 142 and repeat the process: 1427 / 585

Let's proceed to step 4:
When dividing 1427 by 585, we get 2 with a remainder of 257.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 257 after subtracting 1170 from 1427.
Bring next digit (0) of the dividend behind the 257 and repeat the process: 2570 / 585

Going ahead to step 5:
2570 divided by 585 is 4 with a remainder of 230.
Put 4 as the next digit of the answer. 
Result so far: 124.0
If we take 2340 away from 2570, we end up with 230.
Include the next digit (2) from the dividend after 230, then repeat: 2302 / 585

Let's proceed to step 6:
585 goes into 2302 3 times with a remainder of 547.
The number 3 becomes the next digit in our result. 
Result so far: 1243.0
If we take 1755 away from 2302, we end up with 547.
Bring next digit (8) of the dividend behind the 547 and repeat the process: 5478 / 585

Going ahead to step 7:
585 goes into 5478 9 times with a remainder of 213.
The next digit of our result is 9. 
Result so far: 12439.0
Subtract 5265 from 5478 to get 213.
Fetch the next digit (6) from the dividend, attach it to 213 and continue: 2136 / 585

Going ahead to step 8:
When dividing 2136 by 585, we get 3 with a remainder of 381.
Use 3 as the next digit of our solution. 
Result so far: 124393.0
If we subtract 1755 from 2136, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Step 9:
3810 divided by 585 is 6 with a remainder of 300.
Put 6 as the next digit of the answer. 
Result so far: 124393.6
Deduct 3510 from 3810 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 10:
If we divide 3000 by 585, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 124393.65
Subtracting 2925 from 3000 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 11:
585 goes into 750 1 times with a remainder of 165.
Record the quotient 1 as the next digit in the result. 
Result so far: 124393.651
Subtracting 585 from 750 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 12:
When dividing 1650 by 585, we get 2 with a remainder of 480.
The number 2 becomes the next digit in our result. 
Result so far: 124393.6512
The remainder is 480 after subtracting 1170 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 13:
The number 585 fits into 4800 8 times, leaving a remainder of 120.
The next digit of our result is 8. 
Result so far: 124393.65128
Subtract 4680 from 4800 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 14:
585 goes into 1200 2 times with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 124393.651282
Subtracting 1170 from 1200 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 15:
The number 585 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 124393.651282
Subtracting 0 from 300 leaves us with 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 16:
When dividing 3000 by 585, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 124393.65128205
Subtract 2925 from 3000 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

After the division, we end up with 124393.65128205 and a remainder of 7.5e-08.
