851489 ÷ 65 
The aim is to understand the frequency of 65 in 851489.

Going ahead to step 1:
65 can be fit into 8 0 times, resulting in 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 (5) from the dividend, add it to 8, then carry on: 85 / 65

Going ahead to step 2:
When dividing 85 by 65, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 65 from 85 to get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 65

Moving on to step 3:
When dividing 201 by 65, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 195 from 201 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 65

On to step 4:
The number 65 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
If we take 0 away from 64, we end up with 64.
Append the next digit (8) from the dividend to 64 and continue with: 648 / 65

Going ahead to step 5:
If we divide 648 by 65, we get 9 and a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 1309.0
If we take 585 away from 648, we end up with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 65

Advancing to step 6:
639 divided by 65 is 9 with a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 13099.0
If we take 585 away from 639, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
65 goes into 540 8 times with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 13099.8
If we subtract 520 from 540, we 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 8:
65 goes into 200 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 13099.83
Subtract 195 from 200 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
When dividing 50 by 65, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 13099.83
If we subtract 0 from 50, we 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.

Let's proceed to step 10:
When dividing 500 by 65, we get 7 with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 13099.8307
If we subtract 455 from 500, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
The number 65 fits into 450 6 times, leaving a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 13099.83076
If we take 390 away from 450, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
65 can be fit into 600 9 times, resulting in a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 13099.830769
If we subtract 585 from 600, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
150 divided by 65 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 13099.8307692
The remainder is 20 after subtracting 130 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
65 goes into 200 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 13099.83076923
If we subtract 195 from 200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 13099.83076923 with a remainder of 5e-09.
