78813744 ÷ 812 
We want to divide 78813744 by 812.

Going ahead to step 1:
7 divided by 812 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 812

On to step 2:
The number 812 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Append the next digit (8) from the dividend to 78 and continue with: 788 / 812

Moving on to step 3:
812 goes into 788 0 times with a remainder of 788.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 788 leaves us with 788.
Include the next digit (1) from the dividend after 788, then repeat: 7881 / 812

Going ahead to step 4:
The number 812 fits into 7881 9 times, leaving a remainder of 573.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7308 from 7881, we get 573.
Include the next digit (3) from the dividend after 573, then repeat: 5733 / 812

Going ahead to step 5:
812 goes into 5733 7 times with a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Deduct 5684 from 5733 and we're left with 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 812

Let's proceed to step 6:
When dividing 497 by 812, we get 0 with a remainder of 497.
The number 0 becomes the next digit in our result. 
Result so far: 970.0
If we subtract 0 from 497, we get 497.
Append the next digit (4) from the dividend to 497 and continue with: 4974 / 812

Step 7:
812 can be fit into 4974 6 times, resulting in a remainder of 102.
Put 6 as the next digit of the answer. 
Result so far: 9706.0
The remainder is 102 after subtracting 4872 from 4974.
Append the next digit (4) from the dividend to 102 and continue with: 1024 / 812

Moving on to step 8:
1024 divided by 812 is 1 with a remainder of 212.
Record the quotient 1 as the next digit in the result. 
Result so far: 97061.0
If we take 812 away from 1024, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 9:
2120 divided by 812 is 2 with a remainder of 496.
The number 2 becomes the next digit in our result. 
Result so far: 97061.2
The remainder is 496 after subtracting 1624 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 10:
812 can be fit into 4960 6 times, resulting in a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 97061.26
If we subtract 4872 from 4960, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 11:
812 goes into 880 1 times with a remainder of 68.
Use 1 as the next digit of our solution. 
Result so far: 97061.261
The remainder is 68 after subtracting 812 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
812 goes into 680 0 times with a remainder of 680.
Record the quotient 0 as the next digit in the result. 
Result so far: 97061.261
If we take 0 away from 680, we end up with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

On to step 13:
When dividing 6800 by 812, we get 8 with a remainder of 304.
Record the quotient 8 as the next digit in the result. 
Result so far: 97061.26108
Subtract 6496 from 6800 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 14:
The number 812 fits into 3040 3 times, leaving a remainder of 604.
Use 3 as the next digit of our solution. 
Result so far: 97061.261083
Deduct 2436 from 3040 and we're left with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Advancing to step 15:
812 can be fit into 6040 7 times, resulting in a remainder of 356.
Use 7 as the next digit of our solution. 
Result so far: 97061.2610837
Subtracting 5684 from 6040 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 16:
The number 812 fits into 3560 4 times, leaving a remainder of 312.
Record the quotient 4 as the next digit in the result. 
Result so far: 97061.26108374
Subtracting 3248 from 3560 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final outcome is 97061.26108374, with a leftover of 3.12e-07.
