We divide 13521080 by 65
The aim is to understand the frequency of 65 in 13521080.

On to step 1:
1 divided by 65 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 65

On to step 2:
65 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 65

Moving on to step 3:
If we divide 135 by 65, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 130 from 135, we get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 65

Moving on to step 4:
If we divide 52 by 65, we get 0 and a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 52, we get 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 65

On to step 5:
If we divide 521 by 65, we get 8 and a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 208.0
The remainder is 1 after subtracting 520 from 521.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 65

Step 6:
65 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2080.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 65

Let's proceed to step 7:
65 goes into 108 1 times with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 20801.0
If we subtract 65 from 108, we get 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 65

Let's proceed to step 8:
If we divide 430 by 65, we get 6 and a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 208016.0
Subtracting 390 from 430 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
65 goes into 400 6 times with a remainder of 10.
The next digit of our result is 6. 
Result so far: 208016.6
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
If we divide 100 by 65, we get 1 and a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 208016.61
The remainder is 35 after subtracting 65 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
350 divided by 65 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 208016.615
Subtract 325 from 350 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
When dividing 250 by 65, we get 3 with a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 208016.6153
Subtracting 195 from 250 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 13:
65 goes into 550 8 times with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 208016.61538
Subtracting 520 from 550 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
If we divide 300 by 65, we get 4 and a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 208016.615384
Subtract 260 from 300 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
65 goes into 400 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 208016.6153846
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 16:
When dividing 100 by 65, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 208016.61538461
Deduct 65 from 100 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 208016.61538461 with a balance of 3.5e-08.
