We're dividing 13937764 by 689 
The aim is to understand the frequency of 689 in 13937764.

On to step 1:
689 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 689

Going ahead to step 2:
689 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 689

Going ahead to step 3:
If we divide 139 by 689, we get 0 and a remainder of 139.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 139, we get 139.
Fetch the next digit (3) from the dividend, attach it to 139 and continue: 1393 / 689

Step 4:
The number 689 fits into 1393 2 times, leaving a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 15 after subtracting 1378 from 1393.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 689

Moving on to step 5:
The number 689 fits into 157 0 times, leaving a remainder of 157.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 157 and we're left with 157.
Append the next digit (7) from the dividend to 157 and continue with: 1577 / 689

Moving on to step 6:
689 goes into 1577 2 times with a remainder of 199.
Write down 2 as next digit of the result. 
Result so far: 202.0
Subtract 1378 from 1577 to get 199.
Grab the next digit (6) from the dividend, add it to 199, then carry on: 1996 / 689

Going ahead to step 7:
689 goes into 1996 2 times with a remainder of 618.
Write down 2 as next digit of the result. 
Result so far: 2022.0
If we take 1378 away from 1996, we end up with 618.
Fetch the next digit (4) from the dividend, attach it to 618 and continue: 6184 / 689

On to step 8:
The number 689 fits into 6184 8 times, leaving a remainder of 672.
The number 8 becomes the next digit in our result. 
Result so far: 20228.0
The remainder is 672 after subtracting 5512 from 6184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Going ahead to step 9:
When dividing 6720 by 689, we get 9 with a remainder of 519.
Use 9 as the next digit of our solution. 
Result so far: 20228.9
If we take 6201 away from 6720, we end up with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

On to step 10:
689 can be fit into 5190 7 times, resulting in a remainder of 367.
Use 7 as the next digit of our solution. 
Result so far: 20228.97
Subtracting 4823 from 5190 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

On to step 11:
The number 689 fits into 3670 5 times, leaving a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 20228.975
Subtract 3445 from 3670 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 12:
2250 divided by 689 is 3 with a remainder of 183.
The number 3 becomes the next digit in our result. 
Result so far: 20228.9753
If we subtract 2067 from 2250, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Let's proceed to step 13:
When dividing 1830 by 689, we get 2 with a remainder of 452.
The next digit of our result is 2. 
Result so far: 20228.97532
Subtracting 1378 from 1830 leaves us with 452.
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 14:
689 goes into 4520 6 times with a remainder of 386.
Put 6 as the next digit of the answer. 
Result so far: 20228.975326
Subtracting 4134 from 4520 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 15:
When dividing 3860 by 689, we get 5 with a remainder of 415.
Record the quotient 5 as the next digit in the result. 
Result so far: 20228.9753265
Subtract 3445 from 3860 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 16:
689 can be fit into 4150 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 20228.97532656
Deduct 4134 from 4150 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 20228.97532656 with a remaining 1.6e-08.
