84815588 divided by 684 
The aim is to understand the frequency of 684 in 84815588.

Going ahead to step 1:
684 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 684

Let's proceed to step 2:
684 goes into 84 0 times with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Include the next digit (8) from the dividend after 84, then repeat: 848 / 684

Let's proceed to step 3:
When dividing 848 by 684, we get 1 with a remainder of 164.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 684 from 848 and we're left with 164.
Fetch the next digit (1) from the dividend, attach it to 164 and continue: 1641 / 684

On to step 4:
684 goes into 1641 2 times with a remainder of 273.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 1368 from 1641 and we're left with 273.
Take the next digit (5) from the dividend and append it to 273, then repeat: 2735 / 684

Step 5:
684 goes into 2735 3 times with a remainder of 683.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Subtracting 2052 from 2735 leaves us with 683.
Bring next digit (5) of the dividend behind the 683 and repeat the process: 6835 / 684

Advancing to step 6:
684 goes into 6835 9 times with a remainder of 679.
The number 9 becomes the next digit in our result. 
Result so far: 1239.0
If we take 6156 away from 6835, we end up with 679.
Take the next digit (8) from the dividend and append it to 679, then repeat: 6798 / 684

Moving on to step 7:
684 goes into 6798 9 times with a remainder of 642.
Put 9 as the next digit of the answer. 
Result so far: 12399.0
The remainder is 642 after subtracting 6156 from 6798.
Take the next digit (8) from the dividend and append it to 642, then repeat: 6428 / 684

On to step 8:
When dividing 6428 by 684, we get 9 with a remainder of 272.
The number 9 becomes the next digit in our result. 
Result so far: 123999.0
If we take 6156 away from 6428, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 9:
684 goes into 2720 3 times with a remainder of 668.
Record the quotient 3 as the next digit in the result. 
Result so far: 123999.3
Deduct 2052 from 2720 and we're left with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

On to step 10:
The number 684 fits into 6680 9 times, leaving a remainder of 524.
Put 9 as the next digit of the answer. 
Result so far: 123999.39
Subtract 6156 from 6680 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 11:
The number 684 fits into 5240 7 times, leaving a remainder of 452.
The number 7 becomes the next digit in our result. 
Result so far: 123999.397
The remainder is 452 after subtracting 4788 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 12:
When dividing 4520 by 684, we get 6 with a remainder of 416.
Write down 6 as next digit of the result. 
Result so far: 123999.3976
Subtracting 4104 from 4520 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 13:
4160 divided by 684 is 6 with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 123999.39766
Subtract 4104 from 4160 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 123999.39766, with a leftover of 5.6e-05.
