Let's divide 78491155 by 812
We want to divide 78491155 by 812.

Moving on to step 1:
7 divided by 812 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 812

Moving on to step 2:
812 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 812

Let's proceed to step 3:
The number 812 fits into 784 0 times, leaving a remainder of 784.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 784 to get 784.
Include the next digit (9) from the dividend after 784, then repeat: 7849 / 812

On to step 4:
812 goes into 7849 9 times with a remainder of 541.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 7308 from 7849 to get 541.
Bring next digit (1) of the dividend behind the 541 and repeat the process: 5411 / 812

Let's proceed to step 5:
If we divide 5411 by 812, we get 6 and a remainder of 539.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Subtract 4872 from 5411 to get 539.
Take the next digit (1) from the dividend and append it to 539, then repeat: 5391 / 812

Step 6:
When dividing 5391 by 812, we get 6 with a remainder of 519.
The next digit of our result is 6. 
Result so far: 966.0
If we subtract 4872 from 5391, we get 519.
Take the next digit (5) from the dividend and append it to 519, then repeat: 5195 / 812

Step 7:
5195 divided by 812 is 6 with a remainder of 323.
Put 6 as the next digit of the answer. 
Result so far: 9666.0
Subtracting 4872 from 5195 leaves us with 323.
Fetch the next digit (5) from the dividend, attach it to 323 and continue: 3235 / 812

Moving on to step 8:
When dividing 3235 by 812, we get 3 with a remainder of 799.
The next digit of our result is 3. 
Result so far: 96663.0
Subtracting 2436 from 3235 leaves us with 799.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7990, and continue the process.

Advancing to step 9:
The number 812 fits into 7990 9 times, leaving a remainder of 682.
Use 9 as the next digit of our solution. 
Result so far: 96663.9
If we subtract 7308 from 7990, we get 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Let's proceed to step 10:
6820 divided by 812 is 8 with a remainder of 324.
Record the quotient 8 as the next digit in the result. 
Result so far: 96663.98
Deduct 6496 from 6820 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 11:
812 can be fit into 3240 3 times, resulting in a remainder of 804.
The number 3 becomes the next digit in our result. 
Result so far: 96663.983
Deduct 2436 from 3240 and we're left with 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Advancing to step 12:
The number 812 fits into 8040 9 times, leaving a remainder of 732.
The next digit of our result is 9. 
Result so far: 96663.9839
If we subtract 7308 from 8040, we get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Step 13:
The number 812 fits into 7320 9 times, leaving a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 96663.98399
Subtracting 7308 from 7320 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 96663.98399 and a remainder of 1.2e-05.
