Let's divide 72510790 by 878
We want to divide 72510790 by 878.

Step 1:
878 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 878

Going ahead to step 2:
72 divided by 878 is 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 878

Step 3:
If we divide 725 by 878, we get 0 and a remainder of 725.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 725 after subtracting 0 from 725.
Take the next digit (1) from the dividend and append it to 725, then repeat: 7251 / 878

Step 4:
The number 878 fits into 7251 8 times, leaving a remainder of 227.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 7024 away from 7251, we end up with 227.
Append the next digit (0) from the dividend to 227 and continue with: 2270 / 878

Step 5:
The number 878 fits into 2270 2 times, leaving a remainder of 514.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Subtracting 1756 from 2270 leaves us with 514.
Fetch the next digit (7) from the dividend, attach it to 514 and continue: 5147 / 878

Advancing to step 6:
878 goes into 5147 5 times with a remainder of 757.
Put 5 as the next digit of the answer. 
Result so far: 825.0
If we take 4390 away from 5147, we end up with 757.
Include the next digit (9) from the dividend after 757, then repeat: 7579 / 878

Moving on to step 7:
878 can be fit into 7579 8 times, resulting in a remainder of 555.
Write down 8 as next digit of the result. 
Result so far: 8258.0
Deduct 7024 from 7579 and we're left with 555.
Bring next digit (0) of the dividend behind the 555 and repeat the process: 5550 / 878

Advancing to step 8:
If we divide 5550 by 878, we get 6 and a remainder of 282.
Put 6 as the next digit of the answer. 
Result so far: 82586.0
The remainder is 282 after subtracting 5268 from 5550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 9:
878 can be fit into 2820 3 times, resulting in a remainder of 186.
Write down 3 as next digit of the result. 
Result so far: 82586.3
Subtract 2634 from 2820 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 10:
The number 878 fits into 1860 2 times, leaving a remainder of 104.
The next digit of our result is 2. 
Result so far: 82586.32
Deduct 1756 from 1860 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 11:
When dividing 1040 by 878, we get 1 with a remainder of 162.
Put 1 as the next digit of the answer. 
Result so far: 82586.321
If we subtract 878 from 1040, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 12:
When dividing 1620 by 878, we get 1 with a remainder of 742.
Put 1 as the next digit of the answer. 
Result so far: 82586.3211
Deduct 878 from 1620 and we're left with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

The final result is 82586.3211 with a remainder of 0.00742.
