We're dividing 80722370 by 31 
We want to figure out the number of times 80722370 can be divided by 31.

Step 1:
8 divided by 31 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 31

Going ahead to step 2:
When dividing 80 by 31, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 62 away from 80, we end up with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 31

On to step 3:
The number 31 fits into 187 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtracting 186 from 187 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 31

Advancing to step 4:
The number 31 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 260.0
Subtract 0 from 12 to get 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 31

Let's proceed to step 5:
31 goes into 122 3 times with a remainder of 29.
The next digit of our result is 3. 
Result so far: 2603.0
If we subtract 93 from 122, we get 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 31

On to step 6:
The number 31 fits into 293 9 times, leaving a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 26039.0
Subtracting 279 from 293 leaves us with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 31

Moving on to step 7:
The number 31 fits into 147 4 times, leaving a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 260394.0
Deduct 124 from 147 and we're left with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 31

On to step 8:
31 can be fit into 230 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 2603947.0
If we take 217 away from 230, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
31 can be fit into 130 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 2603947.4
If we take 124 away from 130, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
If we divide 60 by 31, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 2603947.41
If we take 31 away from 60, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 11:
When dividing 290 by 31, we get 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 2603947.419
Subtracting 279 from 290 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 12:
The number 31 fits into 110 3 times, leaving a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 2603947.4193
The remainder is 17 after subtracting 93 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
31 can be fit into 170 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2603947.41935
Deduct 155 from 170 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
150 divided by 31 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 2603947.419354
The remainder is 26 after subtracting 124 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 15:
If we divide 260 by 31, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 2603947.4193548
Subtracting 248 from 260 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 16:
The number 31 fits into 120 3 times, leaving a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 2603947.41935483
Subtract 93 from 120 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The quotient of the division is 2603947.41935483, and the remainder is 2.7e-08.
