819379 ÷ 80 
We want to figure out the number of times 819379 can be divided by 80.

Going ahead to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 80

Advancing to step 2:
80 goes into 81 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 80 from 81.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 80

Advancing to step 3:
19 divided by 80 is 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 19, we end up with 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 80

Step 4:
If we divide 193 by 80, we get 2 and a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Subtracting 160 from 193 leaves us with 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 80

Step 5:
80 can be fit into 337 4 times, resulting in a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 1024.0
The remainder is 17 after subtracting 320 from 337.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 80

Moving on to step 6:
The number 80 fits into 179 2 times, leaving a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 10242.0
Subtracting 160 from 179 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
When dividing 190 by 80, we get 2 with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 10242.2
If we subtract 160 from 190, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
The number 80 fits into 300 3 times, leaving a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 10242.23
Subtract 240 from 300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 10242.237
If we take 560 away from 600, we end up 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 10:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10242.2375
If we take 400 away from 400, 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 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10242.2375
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.

On to step 12:
80 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: 10242.2375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 10242.2375 with a balance of 0.0.
