We look at the division of 48522681 by 684 
The aim is to understand the frequency of 684 in 48522681.

Moving on to step 1:
The number 684 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 684

On to step 2:
When dividing 48 by 684, we get 0 with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 684

Going ahead to step 3:
485 divided by 684 is 0 with a remainder of 485.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 485 after subtracting 0 from 485.
Include the next digit (2) from the dividend after 485, then repeat: 4852 / 684

Step 4:
684 goes into 4852 7 times with a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 4788 from 4852 leaves us with 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 684

On to step 5:
684 can be fit into 642 0 times, resulting in a remainder of 642.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Deduct 0 from 642 and we're left with 642.
Bring next digit (6) of the dividend behind the 642 and repeat the process: 6426 / 684

Let's proceed to step 6:
6426 divided by 684 is 9 with a remainder of 270.
Use 9 as the next digit of our solution. 
Result so far: 709.0
Subtract 6156 from 6426 to get 270.
Include the next digit (8) from the dividend after 270, then repeat: 2708 / 684

On to step 7:
684 goes into 2708 3 times with a remainder of 656.
Write down 3 as next digit of the result. 
Result so far: 7093.0
Subtracting 2052 from 2708 leaves us with 656.
Fetch the next digit (1) from the dividend, attach it to 656 and continue: 6561 / 684

Moving on to step 8:
684 can be fit into 6561 9 times, resulting in a remainder of 405.
Write down 9 as next digit of the result. 
Result so far: 70939.0
Subtract 6156 from 6561 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 9:
If we divide 4050 by 684, we get 5 and a remainder of 630.
Use 5 as the next digit of our solution. 
Result so far: 70939.5
If we take 3420 away from 4050, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 10:
When dividing 6300 by 684, we get 9 with a remainder of 144.
Put 9 as the next digit of the answer. 
Result so far: 70939.59
Subtract 6156 from 6300 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 11:
When dividing 1440 by 684, we get 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 70939.592
The remainder is 72 after subtracting 1368 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 12:
When dividing 720 by 684, we get 1 with a remainder of 36.
The next digit of our result is 1. 
Result so far: 70939.5921
If we subtract 684 from 720, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
If we divide 360 by 684, we get 0 and a remainder of 360.
The next digit of our result is 0. 
Result so far: 70939.5921
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 14:
If we divide 3600 by 684, we get 5 and a remainder of 180.
The next digit of our result is 5. 
Result so far: 70939.592105
Subtracting 3420 from 3600 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 15:
When dividing 1800 by 684, we get 2 with a remainder of 432.
The number 2 becomes the next digit in our result. 
Result so far: 70939.5921052
Subtracting 1368 from 1800 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 16:
If we divide 4320 by 684, we get 6 and a remainder of 216.
The number 6 becomes the next digit in our result. 
Result so far: 70939.59210526
The remainder is 216 after subtracting 4104 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

After the division, we end up with 70939.59210526 and a remainder of 2.16e-07.
