13764429 divided by 80 
Our goal is to divide 13764429 by 80.

Let's proceed to step 1:
If we divide 1 by 80, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 80

Moving on to step 2:
When dividing 13 by 80, we get 0 with 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.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 80

Going ahead to step 3:
The number 80 fits into 137 1 times, leaving a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 80 from 137 leaves us with 57.
Fetch the next digit (6) from the dividend, attach it to 57 and continue: 576 / 80

Let's proceed to step 4:
576 divided by 80 is 7 with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 560 from 576, we get 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 80

Advancing to step 5:
80 can be fit into 164 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 172.0
Subtract 160 from 164 to get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 80

Step 6:
When dividing 44 by 80, we get 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 1720.0
Subtract 0 from 44 to get 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 80

Going ahead to step 7:
80 goes into 442 5 times with a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 17205.0
The remainder is 42 after subtracting 400 from 442.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 80

Let's proceed to step 8:
429 divided by 80 is 5 with a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 172055.0
The remainder is 29 after subtracting 400 from 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
When dividing 290 by 80, we get 3 with a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 172055.3
If we subtract 240 from 290, 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.

Step 10:
The number 80 fits into 500 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 172055.36
If we take 480 away from 500, we end up 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.

Advancing to step 11:
The number 80 fits into 200 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 172055.362
Deduct 160 from 200 and we're left 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.

Moving on to step 12:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 172055.3625
Subtracting 400 from 400 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.

Step 13:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 172055.3625
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.

Moving on to step 14:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 172055.3625
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 final result is 172055.3625 with a remainder of 0.0.
