We look at the division of 71861568 by 904 
We want to figure out the number of times 71861568 can be divided by 904.

Let's proceed to step 1:
When dividing 7 by 904, 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.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 904

Step 2:
71 divided by 904 is 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Grab the next digit (8) from the dividend, add it to 71, then carry on: 718 / 904

Going ahead to step 3:
718 divided by 904 is 0 with a remainder of 718.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 718 to get 718.
Grab the next digit (6) from the dividend, add it to 718, then carry on: 7186 / 904

Going ahead to step 4:
904 goes into 7186 7 times with a remainder of 858.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 858 after subtracting 6328 from 7186.
Take the next digit (1) from the dividend and append it to 858, then repeat: 8581 / 904

Advancing to step 5:
904 can be fit into 8581 9 times, resulting in a remainder of 445.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtracting 8136 from 8581 leaves us with 445.
Grab the next digit (5) from the dividend, add it to 445, then carry on: 4455 / 904

On to step 6:
904 can be fit into 4455 4 times, resulting in a remainder of 839.
Put 4 as the next digit of the answer. 
Result so far: 794.0
If we take 3616 away from 4455, we end up with 839.
Bring next digit (6) of the dividend behind the 839 and repeat the process: 8396 / 904

Step 7:
904 goes into 8396 9 times with a remainder of 260.
Use 9 as the next digit of our solution. 
Result so far: 7949.0
Subtracting 8136 from 8396 leaves us with 260.
Take the next digit (8) from the dividend and append it to 260, then repeat: 2608 / 904

Going ahead to step 8:
The number 904 fits into 2608 2 times, leaving a remainder of 800.
Use 2 as the next digit of our solution. 
Result so far: 79492.0
The remainder is 800 after subtracting 1808 from 2608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 9:
The number 904 fits into 8000 8 times, leaving a remainder of 768.
The number 8 becomes the next digit in our result. 
Result so far: 79492.8
Deduct 7232 from 8000 and we're left with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Going ahead to step 10:
904 can be fit into 7680 8 times, resulting in a remainder of 448.
Use 8 as the next digit of our solution. 
Result so far: 79492.88
The remainder is 448 after subtracting 7232 from 7680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final result is 79492.88 with a remainder of 0.448.
