Let's divide 71643841 by 764
We want to figure out the number of times 71643841 can be divided by 764.

Moving on to step 1:
764 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 764

Let's proceed to step 2:
764 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 764

Step 3:
764 goes into 716 0 times with a remainder of 716.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 716 and we're left with 716.
Fetch the next digit (4) from the dividend, attach it to 716 and continue: 7164 / 764

Going ahead to step 4:
764 can be fit into 7164 9 times, resulting in a remainder of 288.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 6876 from 7164 to get 288.
Append the next digit (3) from the dividend to 288 and continue with: 2883 / 764

Step 5:
The number 764 fits into 2883 3 times, leaving a remainder of 591.
Put 3 as the next digit of the answer. 
Result so far: 93.0
Subtracting 2292 from 2883 leaves us with 591.
Include the next digit (8) from the dividend after 591, then repeat: 5918 / 764

Let's proceed to step 6:
When dividing 5918 by 764, we get 7 with a remainder of 570.
Put 7 as the next digit of the answer. 
Result so far: 937.0
If we subtract 5348 from 5918, we get 570.
Grab the next digit (4) from the dividend, add it to 570, then carry on: 5704 / 764

Advancing to step 7:
If we divide 5704 by 764, we get 7 and a remainder of 356.
The number 7 becomes the next digit in our result. 
Result so far: 9377.0
If we subtract 5348 from 5704, we get 356.
Grab the next digit (1) from the dividend, add it to 356, then carry on: 3561 / 764

Let's proceed to step 8:
764 can be fit into 3561 4 times, resulting in a remainder of 505.
The number 4 becomes the next digit in our result. 
Result so far: 93774.0
Deduct 3056 from 3561 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Moving on to step 9:
When dividing 5050 by 764, we get 6 with a remainder of 466.
The number 6 becomes the next digit in our result. 
Result so far: 93774.6
If we take 4584 away from 5050, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Step 10:
If we divide 4660 by 764, we get 6 and a remainder of 76.
The next digit of our result is 6. 
Result so far: 93774.66
Subtracting 4584 from 4660 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 93774.66 and a remainder of 0.076.
