71931779 ÷ 17 
Let's see how many times 17 fits into 71931779.

Let's proceed to step 1:
17 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 17

Step 2:
The number 17 fits into 71 4 times, leaving a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 68 from 71 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 17

Going ahead to step 3:
The number 17 fits into 39 2 times, leaving a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 34 away from 39, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 17

Going ahead to step 4:
If we divide 53 by 17, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 423.0
Deduct 51 from 53 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 17

Moving on to step 5:
21 divided by 17 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 4231.0
The remainder is 4 after subtracting 17 from 21.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 17

Going ahead to step 6:
17 goes into 47 2 times with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 42312.0
If we subtract 34 from 47, we get 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 17

Going ahead to step 7:
17 can be fit into 137 8 times, resulting in a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 423128.0
Deduct 136 from 137 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 17

Moving on to step 8:
17 can be fit into 19 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 4231281.0
If we take 17 away from 19, we end up 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:
17 can be fit into 20 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 4231281.1
If we subtract 17 from 20, we get 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 10:
When dividing 30 by 17, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 4231281.11
If we take 17 away from 30, 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.

The final result is 4231281.11 with a remainder of 0.013.
