We're dividing 71756515 by 577 
Let's see how many times 577 fits into 71756515.

Moving on to step 1:
The number 577 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 577

Advancing to step 2:
577 goes into 71 0 times with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Append the next digit (7) from the dividend to 71 and continue with: 717 / 577

Step 3:
The number 577 fits into 717 1 times, leaving a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 577 from 717 leaves us with 140.
Grab the next digit (5) from the dividend, add it to 140, then carry on: 1405 / 577

Going ahead to step 4:
1405 divided by 577 is 2 with a remainder of 251.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1154 from 1405 leaves us with 251.
Append the next digit (6) from the dividend to 251 and continue with: 2516 / 577

Moving on to step 5:
577 goes into 2516 4 times with a remainder of 208.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Subtracting 2308 from 2516 leaves us with 208.
Take the next digit (5) from the dividend and append it to 208, then repeat: 2085 / 577

Step 6:
When dividing 2085 by 577, we get 3 with a remainder of 354.
Put 3 as the next digit of the answer. 
Result so far: 1243.0
If we take 1731 away from 2085, we end up with 354.
Bring next digit (1) of the dividend behind the 354 and repeat the process: 3541 / 577

Advancing to step 7:
3541 divided by 577 is 6 with a remainder of 79.
Write down 6 as next digit of the result. 
Result so far: 12436.0
Subtract 3462 from 3541 to get 79.
Bring next digit (5) of the dividend behind the 79 and repeat the process: 795 / 577

Let's proceed to step 8:
The number 577 fits into 795 1 times, leaving a remainder of 218.
The number 1 becomes the next digit in our result. 
Result so far: 124361.0
Deduct 577 from 795 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 9:
2180 divided by 577 is 3 with a remainder of 449.
The next digit of our result is 3. 
Result so far: 124361.3
Subtracting 1731 from 2180 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

On to step 10:
If we divide 4490 by 577, we get 7 and a remainder of 451.
Put 7 as the next digit of the answer. 
Result so far: 124361.37
The remainder is 451 after subtracting 4039 from 4490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Step 11:
577 can be fit into 4510 7 times, resulting in a remainder of 471.
Put 7 as the next digit of the answer. 
Result so far: 124361.377
Subtract 4039 from 4510 to get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

The final result is 124361.377 with a remainder of 0.0471.
