13520011 divided by 320 
We want to figure out the number of times 13520011 can be divided by 320.

Going ahead to step 1:
320 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 320

Advancing to step 2:
320 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 320

Going ahead to step 3:
320 goes into 135 0 times with a remainder of 135.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 135, we end up with 135.
Include the next digit (2) from the dividend after 135, then repeat: 1352 / 320

Moving on to step 4:
When dividing 1352 by 320, we get 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 1280 from 1352 and we're left with 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 320

Let's proceed to step 5:
When dividing 720 by 320, we get 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Deduct 640 from 720 and we're left with 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 320

Advancing to step 6:
If we divide 800 by 320, we get 2 and a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 422.0
If we take 640 away from 800, we end up with 160.
Grab the next digit (1) from the dividend, add it to 160, then carry on: 1601 / 320

Moving on to step 7:
320 goes into 1601 5 times with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 4225.0
Deduct 1600 from 1601 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 320

Let's proceed to step 8:
When dividing 11 by 320, we get 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 42250.0
The remainder is 11 after subtracting 0 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
When dividing 110 by 320, we get 0 with a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 42250.0
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
When dividing 1100 by 320, we get 3 with a remainder of 140.
Put 3 as the next digit of the answer. 
Result so far: 42250.03
Deduct 960 from 1100 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
The number 320 fits into 1400 4 times, leaving a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 42250.034
The remainder is 120 after subtracting 1280 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
320 goes into 1200 3 times with a remainder of 240.
Put 3 as the next digit of the answer. 
Result so far: 42250.0343
If we take 960 away from 1200, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
320 can be fit into 2400 7 times, resulting in a remainder of 160.
Use 7 as the next digit of our solution. 
Result so far: 42250.03437
Subtracting 2240 from 2400 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
When dividing 1600 by 320, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 42250.034375
If we subtract 1600 from 1600, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 15:
The number 320 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42250.034375
Deduct 0 from 0 and we're left 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 16:
320 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42250.034375
Deduct 0 from 0 and we're left 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 quotient of the division is 42250.034375, and the remainder is 0.0.
