We look at the division of 13149901 by 80 
We want to figure out the number of times 13149901 can be divided by 80.

Let's proceed to step 1:
80 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of 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 / 80

Advancing to step 2:
If we divide 13 by 80, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 80

Moving on to step 3:
131 divided by 80 is 1 with a remainder of 51.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 80 from 131 leaves us with 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 80

Advancing to step 4:
The number 80 fits into 514 6 times, leaving a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 480 away from 514, we end up with 34.
Grab the next digit (9) from the dividend, add it to 34, then carry on: 349 / 80

Let's proceed to step 5:
When dividing 349 by 80, we get 4 with a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
Deduct 320 from 349 and we're left with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 80

Moving on to step 6:
299 divided by 80 is 3 with a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 1643.0
If we subtract 240 from 299, we get 59.
Fetch the next digit (0) from the dividend, attach it to 59 and continue: 590 / 80

Moving on to step 7:
80 goes into 590 7 times with a remainder of 30.
The next digit of our result is 7. 
Result so far: 16437.0
If we subtract 560 from 590, we get 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 80

Going ahead to step 8:
301 divided by 80 is 3 with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 164373.0
Subtracting 240 from 301 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 9:
The number 80 fits into 610 7 times, leaving a remainder of 50.
The next digit of our result is 7. 
Result so far: 164373.7
The remainder is 50 after subtracting 560 from 610.
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:
80 can be fit into 500 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 164373.76
The remainder is 20 after subtracting 480 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
200 divided by 80 is 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 164373.762
If we subtract 160 from 200, we 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.

Moving on to step 12:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 164373.7625
If we subtract 400 from 400, 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.

Step 13:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 164373.7625
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.

Moving on to step 14:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 164373.7625
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 164373.7625 and a remainder of 0.0.
