We look at the division of 5649963 by 689 
The aim is to understand the frequency of 689 in 5649963.

Step 1:
689 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 689

Going ahead to step 2:
The number 689 fits into 56 0 times, leaving a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 689

Let's proceed to step 3:
When dividing 564 by 689, we get 0 with a remainder of 564.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 564 to get 564.
Include the next digit (9) from the dividend after 564, then repeat: 5649 / 689

Advancing to step 4:
If we divide 5649 by 689, we get 8 and a remainder of 137.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 5512 from 5649, we get 137.
Include the next digit (9) from the dividend after 137, then repeat: 1379 / 689

Let's proceed to step 5:
If we divide 1379 by 689, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Subtract 1378 from 1379 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 689

Moving on to step 6:
16 divided by 689 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 820.0
Subtracting 0 from 16 leaves us with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 689

Moving on to step 7:
689 can be fit into 163 0 times, resulting in a remainder of 163.
Use 0 as the next digit of our solution. 
Result so far: 8200.0
If we take 0 away from 163, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 8:
If we divide 1630 by 689, we get 2 and a remainder of 252.
Put 2 as the next digit of the answer. 
Result so far: 8200.2
Deduct 1378 from 1630 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 9:
689 goes into 2520 3 times with a remainder of 453.
The next digit of our result is 3. 
Result so far: 8200.23
The remainder is 453 after subtracting 2067 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Going ahead to step 10:
When dividing 4530 by 689, we get 6 with a remainder of 396.
The next digit of our result is 6. 
Result so far: 8200.236
Subtracting 4134 from 4530 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 11:
When dividing 3960 by 689, we get 5 with a remainder of 515.
Write down 5 as next digit of the result. 
Result so far: 8200.2365
If we take 3445 away from 3960, we end up with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Step 12:
If we divide 5150 by 689, we get 7 and a remainder of 327.
Record the quotient 7 as the next digit in the result. 
Result so far: 8200.23657
If we take 4823 away from 5150, we end up with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 13:
If we divide 3270 by 689, we get 4 and a remainder of 514.
Record the quotient 4 as the next digit in the result. 
Result so far: 8200.236574
If we subtract 2756 from 3270, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Moving on to step 14:
When dividing 5140 by 689, we get 7 with a remainder of 317.
Use 7 as the next digit of our solution. 
Result so far: 8200.2365747
Subtract 4823 from 5140 to get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

On to step 15:
The number 689 fits into 3170 4 times, leaving a remainder of 414.
Use 4 as the next digit of our solution. 
Result so far: 8200.23657474
Subtracting 2756 from 3170 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Our division results in 8200.23657474 with a remaining 4.14e-07.
