We're dividing 16428898 by 650 
The aim is to understand the frequency of 650 in 16428898.

Advancing to step 1:
When dividing 1 by 650, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 650

Let's proceed to step 2:
If we divide 16 by 650, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 650

Step 3:
The number 650 fits into 164 0 times, leaving a remainder of 164.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 164, we end up with 164.
Fetch the next digit (2) from the dividend, attach it to 164 and continue: 1642 / 650

On to step 4:
650 can be fit into 1642 2 times, resulting in a remainder of 342.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1300 away from 1642, we end up with 342.
Fetch the next digit (8) from the dividend, attach it to 342 and continue: 3428 / 650

Going ahead to step 5:
650 can be fit into 3428 5 times, resulting in a remainder of 178.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 3250 from 3428 to get 178.
Fetch the next digit (8) from the dividend, attach it to 178 and continue: 1788 / 650

Let's proceed to step 6:
If we divide 1788 by 650, we get 2 and a remainder of 488.
The next digit of our result is 2. 
Result so far: 252.0
Subtract 1300 from 1788 to get 488.
Grab the next digit (9) from the dividend, add it to 488, then carry on: 4889 / 650

Advancing to step 7:
650 can be fit into 4889 7 times, resulting in a remainder of 339.
The next digit of our result is 7. 
Result so far: 2527.0
Subtract 4550 from 4889 to get 339.
Append the next digit (8) from the dividend to 339 and continue with: 3398 / 650

Moving on to step 8:
If we divide 3398 by 650, we get 5 and a remainder of 148.
Write down 5 as next digit of the result. 
Result so far: 25275.0
The remainder is 148 after subtracting 3250 from 3398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 9:
If we divide 1480 by 650, we get 2 and a remainder of 180.
Record the quotient 2 as the next digit in the result. 
Result so far: 25275.2
If we subtract 1300 from 1480, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
If we divide 1800 by 650, we get 2 and a remainder of 500.
Write down 2 as next digit of the result. 
Result so far: 25275.22
Deduct 1300 from 1800 and we're left 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.

The final outcome is 25275.22, with a leftover of 0.5.
