We're dividing 98564915 by 689 
The aim is to understand the frequency of 689 in 98564915.

Step 1:
9 divided by 689 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 689

Advancing to step 2:
689 goes into 98 0 times with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Bring next digit (5) of the dividend behind the 98 and repeat the process: 985 / 689

Let's proceed to step 3:
When dividing 985 by 689, we get 1 with a remainder of 296.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 689 from 985 leaves us with 296.
Bring next digit (6) of the dividend behind the 296 and repeat the process: 2966 / 689

Step 4:
689 goes into 2966 4 times with a remainder of 210.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 2756 from 2966, we get 210.
Grab the next digit (4) from the dividend, add it to 210, then carry on: 2104 / 689

On to step 5:
The number 689 fits into 2104 3 times, leaving a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Deduct 2067 from 2104 and we're left with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 689

Let's proceed to step 6:
379 divided by 689 is 0 with a remainder of 379.
The number 0 becomes the next digit in our result. 
Result so far: 1430.0
If we subtract 0 from 379, we get 379.
Fetch the next digit (1) from the dividend, attach it to 379 and continue: 3791 / 689

Going ahead to step 7:
The number 689 fits into 3791 5 times, leaving a remainder of 346.
The number 5 becomes the next digit in our result. 
Result so far: 14305.0
If we take 3445 away from 3791, we end up with 346.
Append the next digit (5) from the dividend to 346 and continue with: 3465 / 689

Moving on to step 8:
689 goes into 3465 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 143055.0
Subtract 3445 from 3465 to 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.

Moving on to step 9:
When dividing 200 by 689, we get 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 143055.0
If we subtract 0 from 200, we get 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 10:
The number 689 fits into 2000 2 times, leaving a remainder of 622.
The number 2 becomes the next digit in our result. 
Result so far: 143055.02
Deduct 1378 from 2000 and we're left with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Going ahead to step 11:
6220 divided by 689 is 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 143055.029
If we subtract 6201 from 6220, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
The number 689 fits into 190 0 times, leaving a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 143055.029
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 13:
The number 689 fits into 1900 2 times, leaving a remainder of 522.
Use 2 as the next digit of our solution. 
Result so far: 143055.02902
Subtracting 1378 from 1900 leaves us with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 14:
When dividing 5220 by 689, we get 7 with a remainder of 397.
Record the quotient 7 as the next digit in the result. 
Result so far: 143055.029027
Deduct 4823 from 5220 and we're left with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Step 15:
When dividing 3970 by 689, we get 5 with a remainder of 525.
The next digit of our result is 5. 
Result so far: 143055.0290275
The remainder is 525 after subtracting 3445 from 3970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Let's proceed to step 16:
The number 689 fits into 5250 7 times, leaving a remainder of 427.
The next digit of our result is 7. 
Result so far: 143055.02902757
Subtract 4823 from 5250 to get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

After the division, we end up with 143055.02902757 and a remainder of 4.27e-07.
