Let's divide 8510643 by 584
The aim is to understand the frequency of 584 in 8510643.

Going ahead to step 1:
If we divide 8 by 584, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 584

Step 2:
584 goes into 85 0 times with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Take the next digit (1) from the dividend and append it to 85, then repeat: 851 / 584

Let's proceed to step 3:
If we divide 851 by 584, we get 1 and a remainder of 267.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 267 after subtracting 584 from 851.
Bring next digit (0) of the dividend behind the 267 and repeat the process: 2670 / 584

Step 4:
The number 584 fits into 2670 4 times, leaving a remainder of 334.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 2336 from 2670 and we're left with 334.
Bring next digit (6) of the dividend behind the 334 and repeat the process: 3346 / 584

Step 5:
When dividing 3346 by 584, we get 5 with a remainder of 426.
Use 5 as the next digit of our solution. 
Result so far: 145.0
Subtracting 2920 from 3346 leaves us with 426.
Take the next digit (4) from the dividend and append it to 426, then repeat: 4264 / 584

Let's proceed to step 6:
The number 584 fits into 4264 7 times, leaving a remainder of 176.
The number 7 becomes the next digit in our result. 
Result so far: 1457.0
Subtracting 4088 from 4264 leaves us with 176.
Grab the next digit (3) from the dividend, add it to 176, then carry on: 1763 / 584

On to step 7:
The number 584 fits into 1763 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 14573.0
Subtracting 1752 from 1763 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
If we divide 110 by 584, we get 0 and a remainder of 110.
The next digit of our result is 0. 
Result so far: 14573.0
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 9:
If we divide 1100 by 584, we get 1 and a remainder of 516.
Record the quotient 1 as the next digit in the result. 
Result so far: 14573.01
If we subtract 584 from 1100, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 10:
If we divide 5160 by 584, we get 8 and a remainder of 488.
Record the quotient 8 as the next digit in the result. 
Result so far: 14573.018
Deduct 4672 from 5160 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 11:
584 goes into 4880 8 times with a remainder of 208.
Put 8 as the next digit of the answer. 
Result so far: 14573.0188
If we take 4672 away from 4880, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The quotient of the division is 14573.0188, and the remainder is 0.00208.
