We're dividing 89837568 by 690 
The aim is to understand the frequency of 690 in 89837568.

On to step 1:
The number 690 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 690

Step 2:
690 can be fit into 89 0 times, resulting in a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Include the next digit (8) from the dividend after 89, then repeat: 898 / 690

Step 3:
When dividing 898 by 690, we get 1 with a remainder of 208.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 690 from 898 leaves us with 208.
Bring next digit (3) of the dividend behind the 208 and repeat the process: 2083 / 690

On to step 4:
When dividing 2083 by 690, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 2070 from 2083 leaves us with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 690

Moving on to step 5:
137 divided by 690 is 0 with a remainder of 137.
Use 0 as the next digit of our solution. 
Result so far: 130.0
Deduct 0 from 137 and we're left with 137.
Include the next digit (5) from the dividend after 137, then repeat: 1375 / 690

Going ahead to step 6:
If we divide 1375 by 690, we get 1 and a remainder of 685.
Write down 1 as next digit of the result. 
Result so far: 1301.0
Subtract 690 from 1375 to get 685.
Include the next digit (6) from the dividend after 685, then repeat: 6856 / 690

Advancing to step 7:
690 can be fit into 6856 9 times, resulting in a remainder of 646.
Record the quotient 9 as the next digit in the result. 
Result so far: 13019.0
If we subtract 6210 from 6856, we get 646.
Bring next digit (8) of the dividend behind the 646 and repeat the process: 6468 / 690

Advancing to step 8:
6468 divided by 690 is 9 with a remainder of 258.
Record the quotient 9 as the next digit in the result. 
Result so far: 130199.0
Subtract 6210 from 6468 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 9:
The number 690 fits into 2580 3 times, leaving a remainder of 510.
The next digit of our result is 3. 
Result so far: 130199.3
Deduct 2070 from 2580 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 10:
690 can be fit into 5100 7 times, resulting in a remainder of 270.
Put 7 as the next digit of the answer. 
Result so far: 130199.37
Deduct 4830 from 5100 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 11:
When dividing 2700 by 690, we get 3 with a remainder of 630.
The number 3 becomes the next digit in our result. 
Result so far: 130199.373
If we take 2070 away from 2700, 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.

Advancing to step 12:
690 can be fit into 6300 9 times, resulting in a remainder of 90.
The next digit of our result is 9. 
Result so far: 130199.3739
If we subtract 6210 from 6300, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 13:
690 goes into 900 1 times with a remainder of 210.
Write down 1 as next digit of the result. 
Result so far: 130199.37391
The remainder is 210 after subtracting 690 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 14:
When dividing 2100 by 690, we get 3 with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 130199.373913
Subtract 2070 from 2100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 15:
690 can be fit into 300 0 times, resulting in a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 130199.373913
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 16:
3000 divided by 690 is 4 with a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 130199.37391304
If we take 2760 away from 3000, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 130199.37391304 and a remainder of 2.4e-07.
