We divide 86200290 by 80
Our goal is to divide 86200290 by 80.

Let's proceed to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 80

Advancing to step 2:
When dividing 86 by 80, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 80 away from 86, we end up with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 80

Moving on to step 3:
80 can be fit into 62 0 times, resulting in a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 62, we get 62.
Take the next digit (0) from the dividend and append it to 62, then repeat: 620 / 80

On to step 4:
80 can be fit into 620 7 times, resulting in a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Deduct 560 from 620 and we're left with 60.
Fetch the next digit (0) from the dividend, attach it to 60 and continue: 600 / 80

On to step 5:
80 can be fit into 600 7 times, resulting in a remainder of 40.
The next digit of our result is 7. 
Result so far: 1077.0
Subtract 560 from 600 to get 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 80

Let's proceed to step 6:
80 can be fit into 402 5 times, resulting in a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 10775.0
If we subtract 400 from 402, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 80

On to step 7:
80 goes into 29 0 times with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 107750.0
If we subtract 0 from 29, we get 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 80

On to step 8:
If we divide 290 by 80, we get 3 and a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 1077503.0
Subtracting 240 from 290 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
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: 1077503.6
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.

Going ahead to step 10:
If we divide 200 by 80, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 1077503.62
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.

Advancing to step 11:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1077503.625
Subtract 400 from 400 to 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.

On to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1077503.625
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.

Advancing to step 13:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1077503.625
If we subtract 0 from 0, 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.

After the division, we end up with 1077503.625 and a remainder of 0.0.
