779999 divided by 31 
Let's see how many times 31 fits into 779999.

Moving on to step 1:
31 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 31

Moving on to step 2:
77 divided by 31 is 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 62 away from 77, we end up with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 31

Advancing to step 3:
31 can be fit into 159 5 times, resulting in a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 155 from 159, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 31

On to step 4:
If we divide 49 by 31, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 251.0
If we take 31 away from 49, we end up with 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 31

Going ahead to step 5:
31 can be fit into 189 6 times, resulting in a remainder of 3.
The next digit of our result is 6. 
Result so far: 2516.0
The remainder is 3 after subtracting 186 from 189.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 31

Going ahead to step 6:
When dividing 39 by 31, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 25161.0
If we subtract 31 from 39, we 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.

On to step 7:
31 goes into 80 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 25161.2
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
If we divide 180 by 31, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 25161.25
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.

On to step 9:
31 can be fit into 250 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 25161.258
The remainder is 2 after subtracting 248 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
When dividing 20 by 31, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 25161.258
Deduct 0 from 20 and we're left with 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 11:
31 goes into 200 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 25161.25806
The remainder is 14 after subtracting 186 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
31 can be fit into 140 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 25161.258064
If we subtract 124 from 140, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
31 can be fit into 160 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 25161.2580645
Subtracting 155 from 160 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 14:
31 can be fit into 50 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 25161.25806451
Subtracting 31 from 50 leaves us 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.

The final outcome is 25161.25806451, with a leftover of 1.9e-08.
