Let's divide 86255803 by 80
We're looking to find how many times 80 goes into 86255803.

Let's proceed to step 1:
8 divided by 80 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 80

Step 2:
If we divide 86 by 80, we get 1 and 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.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 80

Moving on to step 3:
80 can be fit into 62 0 times, resulting in a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 62 and we're left with 62.
Append the next digit (5) from the dividend to 62 and continue with: 625 / 80

Step 4:
When dividing 625 by 80, we get 7 with a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
If we subtract 560 from 625, we get 65.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 80

Advancing to step 5:
80 can be fit into 655 8 times, resulting in a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 1078.0
If we subtract 640 from 655, we get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 80

Step 6:
80 goes into 158 1 times with a remainder of 78.
The next digit of our result is 1. 
Result so far: 10781.0
Subtract 80 from 158 to get 78.
Fetch the next digit (0) from the dividend, attach it to 78 and continue: 780 / 80

Going ahead to step 7:
80 can be fit into 780 9 times, resulting in a remainder of 60.
The next digit of our result is 9. 
Result so far: 107819.0
Subtract 720 from 780 to get 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 80

Let's proceed to step 8:
When dividing 603 by 80, we get 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 1078197.0
Subtract 560 from 603 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
When dividing 430 by 80, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 1078197.5
Subtract 400 from 430 to 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 10:
80 goes into 300 3 times with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 1078197.53
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.

Step 11:
If we divide 600 by 80, we get 7 and a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 1078197.537
Subtract 560 from 600 to 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.

Let's proceed to step 12:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1078197.5375
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1078197.5375
If we take 0 away from 0, 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 14:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 1078197.5375
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.

The final result is 1078197.5375 with a remainder of 0.0.
