We look at the division of 80087538 by 650 
The aim is to understand the frequency of 650 in 80087538.

Advancing 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
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 650

Advancing to step 2:
650 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (0) of the dividend behind the 80 and repeat the process: 800 / 650

Advancing to step 3:
When dividing 800 by 650, we get 1 with a remainder of 150.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 650 away from 800, we end up with 150.
Include the next digit (8) from the dividend after 150, then repeat: 1508 / 650

Let's proceed to step 4:
If we divide 1508 by 650, we get 2 and a remainder of 208.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1300 from 1508 to get 208.
Bring next digit (7) of the dividend behind the 208 and repeat the process: 2087 / 650

Going ahead to step 5:
2087 divided by 650 is 3 with a remainder of 137.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
If we take 1950 away from 2087, we end up with 137.
Fetch the next digit (5) from the dividend, attach it to 137 and continue: 1375 / 650

Going ahead to step 6:
650 can be fit into 1375 2 times, resulting in a remainder of 75.
Use 2 as the next digit of our solution. 
Result so far: 1232.0
The remainder is 75 after subtracting 1300 from 1375.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 650

Step 7:
650 goes into 753 1 times with a remainder of 103.
Write down 1 as next digit of the result. 
Result so far: 12321.0
Subtracting 650 from 753 leaves us with 103.
Fetch the next digit (8) from the dividend, attach it to 103 and continue: 1038 / 650

Advancing to step 8:
When dividing 1038 by 650, we get 1 with a remainder of 388.
Use 1 as the next digit of our solution. 
Result so far: 123211.0
Subtract 650 from 1038 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 9:
650 can be fit into 3880 5 times, resulting in a remainder of 630.
Record the quotient 5 as the next digit in the result. 
Result so far: 123211.5
Deduct 3250 from 3880 and we're left 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.

On to step 10:
6300 divided by 650 is 9 with a remainder of 450.
Use 9 as the next digit of our solution. 
Result so far: 123211.59
If we take 5850 away from 6300, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 11:
When dividing 4500 by 650, we get 6 with a remainder of 600.
Put 6 as the next digit of the answer. 
Result so far: 123211.596
Subtracting 3900 from 4500 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 12:
The number 650 fits into 6000 9 times, leaving a remainder of 150.
Write down 9 as next digit of the result. 
Result so far: 123211.5969
Subtracting 5850 from 6000 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 13:
The number 650 fits into 1500 2 times, leaving a remainder of 200.
Put 2 as the next digit of the answer. 
Result so far: 123211.59692
The remainder is 200 after subtracting 1300 from 1500.
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 14:
650 can be fit into 2000 3 times, resulting in a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 123211.596923
Subtract 1950 from 2000 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 15:
650 goes into 500 0 times with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 123211.596923
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 16:
650 can be fit into 5000 7 times, resulting in a remainder of 450.
The next digit of our result is 7. 
Result so far: 123211.59692307
Deduct 4550 from 5000 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Our division results in 123211.59692307 with a remaining 4.5e-07.
