837488 ÷ 65 
The aim is to understand the frequency of 65 in 837488.

On to step 1:
65 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 65

Moving on to step 2:
When dividing 83 by 65, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 65 from 83 leaves us with 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 65

Going ahead to step 3:
65 can be fit into 187 2 times, resulting in a remainder of 57.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 57 after subtracting 130 from 187.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 65

Advancing to step 4:
574 divided by 65 is 8 with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Subtract 520 from 574 to get 54.
Grab the next digit (8) from the dividend, add it to 54, then carry on: 548 / 65

Advancing to step 5:
If we divide 548 by 65, we get 8 and a remainder of 28.
The next digit of our result is 8. 
Result so far: 1288.0
The remainder is 28 after subtracting 520 from 548.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 65

Advancing to step 6:
When dividing 288 by 65, we get 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 12884.0
If we take 260 away from 288, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
65 can be fit into 280 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 12884.4
Deduct 260 from 280 and we're left 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.

Going ahead to step 8:
200 divided by 65 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 12884.43
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.

Moving on to step 9:
65 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 12884.43
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.

Moving on to step 10:
When dividing 500 by 65, we get 7 with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 12884.4307
The remainder is 45 after subtracting 455 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
65 can be fit into 450 6 times, resulting in a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 12884.43076
Subtract 390 from 450 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
When dividing 600 by 65, we get 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 12884.430769
Subtracting 585 from 600 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
65 can be fit into 150 2 times, resulting in a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 12884.4307692
If we subtract 130 from 150, 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.

Advancing to step 14:
200 divided by 65 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 12884.43076923
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.

After the division, we end up with 12884.43076923 and a remainder of 5e-09.
