Let's divide 86038034 by 80
We're looking to find how many times 80 goes into 86038034.

On to step 1:
8 divided by 80 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 80

Going ahead to step 2:
86 divided by 80 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 80 from 86 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 80

On to step 3:
80 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 60 leaves us with 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 80

On to step 4:
When dividing 603 by 80, we get 7 with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 107.0
Subtracting 560 from 603 leaves us with 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 80

Step 5:
438 divided by 80 is 5 with a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 1075.0
Subtracting 400 from 438 leaves us with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 80

Moving on to step 6:
When dividing 380 by 80, we get 4 with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 10754.0
Subtract 320 from 380 to get 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 80

Step 7:
80 can be fit into 603 7 times, resulting in a remainder of 43.
The next digit of our result is 7. 
Result so far: 107547.0
Subtracting 560 from 603 leaves us with 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 80

Moving on to step 8:
The number 80 fits into 434 5 times, leaving a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 1075475.0
If we subtract 400 from 434, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
If we divide 340 by 80, we get 4 and a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 1075475.4
Subtract 320 from 340 to get 20.
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:
200 divided by 80 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 1075475.42
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.

On to step 11:
If we divide 400 by 80, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1075475.425
Deduct 400 from 400 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:
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: 1075475.425
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.

Step 13:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1075475.425
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.

The quotient of the division is 1075475.425, and the remainder is 0.0.
