7512164 divided by 584 
The aim is to understand the frequency of 584 in 7512164.

Going ahead to step 1:
When dividing 7 by 584, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 584

Advancing to step 2:
The number 584 fits into 75 0 times, leaving a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Fetch the next digit (1) from the dividend, attach it to 75 and continue: 751 / 584

Advancing to step 3:
584 goes into 751 1 times with a remainder of 167.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 167 after subtracting 584 from 751.
Bring next digit (2) of the dividend behind the 167 and repeat the process: 1672 / 584

Moving on to step 4:
The number 584 fits into 1672 2 times, leaving a remainder of 504.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1168 from 1672, we get 504.
Grab the next digit (1) from the dividend, add it to 504, then carry on: 5041 / 584

Going ahead to step 5:
584 goes into 5041 8 times with a remainder of 369.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtract 4672 from 5041 to get 369.
Fetch the next digit (6) from the dividend, attach it to 369 and continue: 3696 / 584

On to step 6:
When dividing 3696 by 584, we get 6 with a remainder of 192.
Record the quotient 6 as the next digit in the result. 
Result so far: 1286.0
Deduct 3504 from 3696 and we're left with 192.
Fetch the next digit (4) from the dividend, attach it to 192 and continue: 1924 / 584

On to step 7:
584 goes into 1924 3 times with a remainder of 172.
Write down 3 as next digit of the result. 
Result so far: 12863.0
If we subtract 1752 from 1924, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 8:
1720 divided by 584 is 2 with a remainder of 552.
The number 2 becomes the next digit in our result. 
Result so far: 12863.2
If we subtract 1168 from 1720, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Moving on to step 9:
584 goes into 5520 9 times with a remainder of 264.
Put 9 as the next digit of the answer. 
Result so far: 12863.29
If we subtract 5256 from 5520, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 10:
584 can be fit into 2640 4 times, resulting in a remainder of 304.
The next digit of our result is 4. 
Result so far: 12863.294
Deduct 2336 from 2640 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 11:
3040 divided by 584 is 5 with a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 12863.2945
If we subtract 2920 from 3040, we 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.

Advancing to step 12:
The number 584 fits into 1200 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 12863.29452
Subtract 1168 from 1200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
320 divided by 584 is 0 with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 12863.29452
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
584 can be fit into 3200 5 times, resulting in a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 12863.2945205
Subtract 2920 from 3200 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 15:
If we divide 2800 by 584, we get 4 and a remainder of 464.
Use 4 as the next digit of our solution. 
Result so far: 12863.29452054
If we subtract 2336 from 2800, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

After the division, we end up with 12863.29452054 and a remainder of 4.64e-07.
