71933863 ÷ 649 
We're looking to find how many times 649 goes into 71933863.

Let's proceed to step 1:
If we divide 7 by 649, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 649

Advancing to step 2:
649 goes into 71 0 times with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Bring next digit (9) of the dividend behind the 71 and repeat the process: 719 / 649

Moving on to step 3:
When dividing 719 by 649, we get 1 with a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 649 from 719 leaves us with 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 649

Going ahead to step 4:
When dividing 703 by 649, we get 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 649 from 703 leaves us with 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 649

Going ahead to step 5:
543 divided by 649 is 0 with a remainder of 543.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
Subtracting 0 from 543 leaves us with 543.
Grab the next digit (8) from the dividend, add it to 543, then carry on: 5438 / 649

Step 6:
5438 divided by 649 is 8 with a remainder of 246.
Write down 8 as next digit of the result. 
Result so far: 1108.0
Deduct 5192 from 5438 and we're left with 246.
Grab the next digit (6) from the dividend, add it to 246, then carry on: 2466 / 649

Step 7:
If we divide 2466 by 649, we get 3 and a remainder of 519.
Put 3 as the next digit of the answer. 
Result so far: 11083.0
If we take 1947 away from 2466, we end up with 519.
Append the next digit (3) from the dividend to 519 and continue with: 5193 / 649

Moving on to step 8:
When dividing 5193 by 649, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 110838.0
Subtract 5192 from 5193 to get 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 9:
649 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 110838.0
If we subtract 0 from 10, we 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 10:
649 can be fit into 100 0 times, resulting in a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 110838.0
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 110838.0, and the remainder is 0.1.
