71779953 ÷ 31 
Let's see how many times 31 fits into 71779953.

Going ahead to step 1:
When dividing 7 by 31, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 31

Advancing to step 2:
31 goes into 71 2 times with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 62 from 71 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 31

Going ahead to step 3:
If we divide 97 by 31, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 93 from 97 to get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 31

Moving on to step 4:
31 can be fit into 47 1 times, resulting in a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 231.0
If we subtract 31 from 47, we get 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 31

On to step 5:
When dividing 169 by 31, we get 5 with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 2315.0
Subtract 155 from 169 to get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 31

Let's proceed to step 6:
The number 31 fits into 149 4 times, leaving a remainder of 25.
The next digit of our result is 4. 
Result so far: 23154.0
If we subtract 124 from 149, we get 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 31

Moving on to step 7:
31 can be fit into 255 8 times, resulting in a remainder of 7.
The next digit of our result is 8. 
Result so far: 231548.0
Subtracting 248 from 255 leaves us with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 31

On to step 8:
When dividing 73 by 31, we get 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 2315482.0
Subtract 62 from 73 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
When dividing 110 by 31, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 2315482.3
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.

Going ahead to step 10:
The number 31 fits into 170 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2315482.35
The remainder is 15 after subtracting 155 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
31 goes into 150 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 2315482.354
Subtract 124 from 150 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
When dividing 260 by 31, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 2315482.3548
If we take 248 away from 260, we end up 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 13:
The number 31 fits into 120 3 times, leaving a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 2315482.35483
Deduct 93 from 120 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 14:
If we divide 270 by 31, we get 8 and a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 2315482.354838
If we take 248 away from 270, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 15:
31 goes into 220 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 2315482.3548387
Subtracting 217 from 220 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 16:
31 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 2315482.3548387
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 2315482.3548387 and a remainder of 3e-08.
