We divide 13491136 by 320
The aim is to understand the frequency of 320 in 13491136.

Moving on to step 1:
320 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 320

Moving on to step 2:
13 divided by 320 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 320

Let's proceed to step 3:
If we divide 134 by 320, we get 0 and a remainder of 134.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 134 leaves us with 134.
Grab the next digit (9) from the dividend, add it to 134, then carry on: 1349 / 320

Moving on to step 4:
1349 divided by 320 is 4 with a remainder of 69.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 1280 away from 1349, we end up with 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 320

Advancing to step 5:
If we divide 691 by 320, we get 2 and a remainder of 51.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we subtract 640 from 691, we get 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 320

Moving on to step 6:
When dividing 511 by 320, we get 1 with a remainder of 191.
Write down 1 as next digit of the result. 
Result so far: 421.0
Subtract 320 from 511 to get 191.
Include the next digit (3) from the dividend after 191, then repeat: 1913 / 320

Advancing to step 7:
The number 320 fits into 1913 5 times, leaving a remainder of 313.
Record the quotient 5 as the next digit in the result. 
Result so far: 4215.0
Subtract 1600 from 1913 to get 313.
Append the next digit (6) from the dividend to 313 and continue with: 3136 / 320

Let's proceed to step 8:
The number 320 fits into 3136 9 times, leaving a remainder of 256.
Put 9 as the next digit of the answer. 
Result so far: 42159.0
If we take 2880 away from 3136, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 9:
320 can be fit into 2560 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 42159.8
If we take 2560 away from 2560, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
320 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42159.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
When dividing 0 by 320, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42159.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 42159.8, with a leftover of 0.0.
