Let's divide 75812779 by 781
We're looking to find how many times 781 goes into 75812779.

Advancing to step 1:
781 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 781

Moving on to step 2:
The number 781 fits into 75 0 times, leaving a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 781

Step 3:
758 divided by 781 is 0 with a remainder of 758.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 758, we get 758.
Grab the next digit (1) from the dividend, add it to 758, then carry on: 7581 / 781

Moving on to step 4:
781 goes into 7581 9 times with a remainder of 552.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 7029 away from 7581, we end up with 552.
Append the next digit (2) from the dividend to 552 and continue with: 5522 / 781

Going ahead to step 5:
781 can be fit into 5522 7 times, resulting in a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we take 5467 away from 5522, we end up with 55.
Include the next digit (7) from the dividend after 55, then repeat: 557 / 781

On to step 6:
If we divide 557 by 781, we get 0 and a remainder of 557.
The next digit of our result is 0. 
Result so far: 970.0
The remainder is 557 after subtracting 0 from 557.
Bring next digit (7) of the dividend behind the 557 and repeat the process: 5577 / 781

Moving on to step 7:
If we divide 5577 by 781, we get 7 and a remainder of 110.
Write down 7 as next digit of the result. 
Result so far: 9707.0
Subtracting 5467 from 5577 leaves us with 110.
Include the next digit (9) from the dividend after 110, then repeat: 1109 / 781

Moving on to step 8:
1109 divided by 781 is 1 with a remainder of 328.
The next digit of our result is 1. 
Result so far: 97071.0
Subtracting 781 from 1109 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 9:
When dividing 3280 by 781, we get 4 with a remainder of 156.
The next digit of our result is 4. 
Result so far: 97071.4
If we subtract 3124 from 3280, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 10:
The number 781 fits into 1560 1 times, leaving a remainder of 779.
Use 1 as the next digit of our solution. 
Result so far: 97071.41
If we subtract 781 from 1560, we get 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

Step 11:
If we divide 7790 by 781, we get 9 and a remainder of 761.
Use 9 as the next digit of our solution. 
Result so far: 97071.419
Subtracting 7029 from 7790 leaves us with 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

Going ahead to step 12:
The number 781 fits into 7610 9 times, leaving a remainder of 581.
Use 9 as the next digit of our solution. 
Result so far: 97071.4199
Subtracting 7029 from 7610 leaves us with 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

The final result is 97071.4199 with a remainder of 0.00581.
