We're dividing 80389716 by 650 
The aim is to understand the frequency of 650 in 80389716.

Let's proceed to step 1:
When dividing 8 by 650, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 650

Advancing to step 2:
When dividing 80 by 650, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (3) from the dividend after 80, then repeat: 803 / 650

On to step 3:
When dividing 803 by 650, we get 1 with a remainder of 153.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 650 from 803, we get 153.
Append the next digit (8) from the dividend to 153 and continue with: 1538 / 650

Let's proceed to step 4:
1538 divided by 650 is 2 with a remainder of 238.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 1300 from 1538 leaves us with 238.
Take the next digit (9) from the dividend and append it to 238, then repeat: 2389 / 650

Step 5:
2389 divided by 650 is 3 with a remainder of 439.
The next digit of our result is 3. 
Result so far: 123.0
If we subtract 1950 from 2389, we get 439.
Include the next digit (7) from the dividend after 439, then repeat: 4397 / 650

Advancing to step 6:
4397 divided by 650 is 6 with a remainder of 497.
Use 6 as the next digit of our solution. 
Result so far: 1236.0
Subtract 3900 from 4397 to get 497.
Take the next digit (1) from the dividend and append it to 497, then repeat: 4971 / 650

Advancing to step 7:
650 goes into 4971 7 times with a remainder of 421.
The number 7 becomes the next digit in our result. 
Result so far: 12367.0
Deduct 4550 from 4971 and we're left with 421.
Take the next digit (6) from the dividend and append it to 421, then repeat: 4216 / 650

Going ahead to step 8:
650 goes into 4216 6 times with a remainder of 316.
Put 6 as the next digit of the answer. 
Result so far: 123676.0
Subtracting 3900 from 4216 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 9:
650 goes into 3160 4 times with a remainder of 560.
Record the quotient 4 as the next digit in the result. 
Result so far: 123676.4
Subtracting 2600 from 3160 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 10:
When dividing 5600 by 650, we get 8 with a remainder of 400.
Record the quotient 8 as the next digit in the result. 
Result so far: 123676.48
Deduct 5200 from 5600 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 11:
The number 650 fits into 4000 6 times, leaving a remainder of 100.
The number 6 becomes the next digit in our result. 
Result so far: 123676.486
Subtracting 3900 from 4000 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
1000 divided by 650 is 1 with a remainder of 350.
The number 1 becomes the next digit in our result. 
Result so far: 123676.4861
Deduct 650 from 1000 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 13:
The number 650 fits into 3500 5 times, leaving a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 123676.48615
The remainder is 250 after subtracting 3250 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 14:
If we divide 2500 by 650, we get 3 and a remainder of 550.
Record the quotient 3 as the next digit in the result. 
Result so far: 123676.486153
If we subtract 1950 from 2500, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 15:
When dividing 5500 by 650, we get 8 with a remainder of 300.
Record the quotient 8 as the next digit in the result. 
Result so far: 123676.4861538
If we take 5200 away from 5500, we end up 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.

Advancing to step 16:
3000 divided by 650 is 4 with a remainder of 400.
Use 4 as the next digit of our solution. 
Result so far: 123676.48615384
If we subtract 2600 from 3000, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 123676.48615384 with a remainder of 4e-07.
