300780 ÷ 31 
We want to divide 300780 by 31.

Going ahead to step 1:
The number 31 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 31

Step 2:
The number 31 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 31

On to step 3:
When dividing 300 by 31, we get 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 21 after subtracting 279 from 300.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 31

Step 4:
31 can be fit into 217 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we subtract 217 from 217, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 31

Let's proceed to step 5:
The number 31 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 970.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 31

On to step 6:
When dividing 80 by 31, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 9702.0
Deduct 62 from 80 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
The number 31 fits into 180 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 9702.5
Subtracting 155 from 180 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
31 goes into 250 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 9702.58
Subtracting 248 from 250 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
31 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 9702.58
If we subtract 0 from 20, we 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.

Advancing to step 10:
When dividing 200 by 31, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 9702.5806
Deduct 186 from 200 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
140 divided by 31 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 9702.58064
Subtracting 124 from 140 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
31 can be fit into 160 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 9702.580645
If we subtract 155 from 160, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
31 goes into 50 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 9702.5806451
If we subtract 31 from 50, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
190 divided by 31 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 9702.58064516
If we take 186 away from 190, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 9702.58064516 with a remainder of 4e-09.
