We look at the division of 69510098 by 684 
The aim is to understand the frequency of 684 in 69510098.

Step 1:
When dividing 6 by 684, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 684

Let's proceed to step 2:
When dividing 69 by 684, we get 0 with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 684

Step 3:
684 goes into 695 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 684 away from 695, we end up with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 684

Let's proceed to step 4:
If we divide 111 by 684, we get 0 and a remainder of 111.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 111 to get 111.
Bring next digit (0) of the dividend behind the 111 and repeat the process: 1110 / 684

Advancing to step 5:
684 can be fit into 1110 1 times, resulting in a remainder of 426.
The next digit of our result is 1. 
Result so far: 101.0
Subtract 684 from 1110 to get 426.
Include the next digit (0) from the dividend after 426, then repeat: 4260 / 684

Step 6:
The number 684 fits into 4260 6 times, leaving a remainder of 156.
Put 6 as the next digit of the answer. 
Result so far: 1016.0
Deduct 4104 from 4260 and we're left with 156.
Bring next digit (9) of the dividend behind the 156 and repeat the process: 1569 / 684

Let's proceed to step 7:
684 goes into 1569 2 times with a remainder of 201.
The number 2 becomes the next digit in our result. 
Result so far: 10162.0
Subtract 1368 from 1569 to get 201.
Include the next digit (8) from the dividend after 201, then repeat: 2018 / 684

Step 8:
684 goes into 2018 2 times with a remainder of 650.
Record the quotient 2 as the next digit in the result. 
Result so far: 101622.0
Subtract 1368 from 2018 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 9:
If we divide 6500 by 684, we get 9 and a remainder of 344.
Use 9 as the next digit of our solution. 
Result so far: 101622.9
If we take 6156 away from 6500, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 10:
3440 divided by 684 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 101622.95
If we subtract 3420 from 3440, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
684 can be fit into 200 0 times, resulting in a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 101622.95
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
684 goes into 2000 2 times with a remainder of 632.
Record the quotient 2 as the next digit in the result. 
Result so far: 101622.9502
The remainder is 632 after subtracting 1368 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Advancing to step 13:
The number 684 fits into 6320 9 times, leaving a remainder of 164.
Record the quotient 9 as the next digit in the result. 
Result so far: 101622.95029
Subtracting 6156 from 6320 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 14:
684 goes into 1640 2 times with a remainder of 272.
The number 2 becomes the next digit in our result. 
Result so far: 101622.950292
If we take 1368 away from 1640, 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.

Moving on to step 15:
684 goes into 2720 3 times with a remainder of 668.
The next digit of our result is 3. 
Result so far: 101622.9502923
Subtract 2052 from 2720 to get 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Advancing to step 16:
684 can be fit into 6680 9 times, resulting in a remainder of 524.
Write down 9 as next digit of the result. 
Result so far: 101622.95029239
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.

The quotient of the division is 101622.95029239, and the remainder is 5.24e-07.
