We look at the division of 15368537 by 650 
The aim is to understand the frequency of 650 in 15368537.

Step 1:
650 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 650

Moving on to step 2:
The number 650 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 650

On to step 3:
When dividing 153 by 650, we get 0 with a remainder of 153.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 153, we end up with 153.
Append the next digit (6) from the dividend to 153 and continue with: 1536 / 650

On to step 4:
The number 650 fits into 1536 2 times, leaving a remainder of 236.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1300 away from 1536, we end up with 236.
Include the next digit (8) from the dividend after 236, then repeat: 2368 / 650

Moving on to step 5:
If we divide 2368 by 650, we get 3 and a remainder of 418.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 1950 from 2368, we get 418.
Append the next digit (5) from the dividend to 418 and continue with: 4185 / 650

Let's proceed to step 6:
650 can be fit into 4185 6 times, resulting in a remainder of 285.
Use 6 as the next digit of our solution. 
Result so far: 236.0
Subtracting 3900 from 4185 leaves us with 285.
Fetch the next digit (3) from the dividend, attach it to 285 and continue: 2853 / 650

Moving on to step 7:
2853 divided by 650 is 4 with a remainder of 253.
The next digit of our result is 4. 
Result so far: 2364.0
Subtract 2600 from 2853 to get 253.
Include the next digit (7) from the dividend after 253, then repeat: 2537 / 650

On to step 8:
650 goes into 2537 3 times with a remainder of 587.
The next digit of our result is 3. 
Result so far: 23643.0
Deduct 1950 from 2537 and we're left with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Let's proceed to step 9:
650 goes into 5870 9 times with a remainder of 20.
The next digit of our result is 9. 
Result so far: 23643.9
If we take 5850 away from 5870, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
650 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 23643.9
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
If we divide 2000 by 650, we get 3 and a remainder of 50.
The next digit of our result is 3. 
Result so far: 23643.903
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.

Advancing to step 12:
650 can be fit into 500 0 times, resulting in a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 23643.903
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 13:
When dividing 5000 by 650, we get 7 with a remainder of 450.
Write down 7 as next digit of the result. 
Result so far: 23643.90307
Subtract 4550 from 5000 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 14:
650 goes into 4500 6 times with a remainder of 600.
Record the quotient 6 as the next digit in the result. 
Result so far: 23643.903076
If we subtract 3900 from 4500, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 15:
650 goes into 6000 9 times with a remainder of 150.
The number 9 becomes the next digit in our result. 
Result so far: 23643.9030769
If we subtract 5850 from 6000, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 16:
1500 divided by 650 is 2 with a remainder of 200.
The next digit of our result is 2. 
Result so far: 23643.90307692
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.

After the division, we end up with 23643.90307692 and a remainder of 2e-07.
