We divide 280369 by 31
We want to figure out the number of times 280369 can be divided by 31.

Moving on to step 1:
31 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 31

Going ahead to step 2:
31 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 31

Advancing to step 3:
If we divide 280 by 31, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 1 after subtracting 279 from 280.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 31

Step 4:
If we divide 13 by 31, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtract 0 from 13 to get 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 31

Let's proceed to step 5:
31 can be fit into 136 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 904.0
Subtracting 124 from 136 leaves us with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 31

On to step 6:
When dividing 129 by 31, we get 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 9044.0
Subtracting 124 from 129 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
When dividing 50 by 31, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 9044.1
If we take 31 away from 50, we end up 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.

Let's proceed to step 8:
The number 31 fits into 190 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 9044.16
If we subtract 186 from 190, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
When dividing 40 by 31, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 9044.161
If we subtract 31 from 40, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
If we divide 90 by 31, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 9044.1612
Subtracting 62 from 90 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
If we divide 280 by 31, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 9044.16129
Subtracting 279 from 280 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
31 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 9044.16129
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 9044.1612903
Deduct 93 from 100 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
70 divided by 31 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 9044.16129032
Subtract 62 from 70 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 9044.16129032 with a remainder of 8e-09.
