78891516 ÷ 807 
We're looking to find how many times 807 goes into 78891516.

Step 1:
The number 807 fits into 7 0 times, leaving 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 (8) from the dividend after 7, then repeat: 78 / 807

Let's proceed to step 2:
807 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 807

Let's proceed to step 3:
788 divided by 807 is 0 with a remainder of 788.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 788 and we're left with 788.
Fetch the next digit (9) from the dividend, attach it to 788 and continue: 7889 / 807

Step 4:
7889 divided by 807 is 9 with a remainder of 626.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 7263 from 7889 to get 626.
Take the next digit (1) from the dividend and append it to 626, then repeat: 6261 / 807

Going ahead to step 5:
When dividing 6261 by 807, we get 7 with a remainder of 612.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we subtract 5649 from 6261, we get 612.
Bring next digit (5) of the dividend behind the 612 and repeat the process: 6125 / 807

On to step 6:
807 can be fit into 6125 7 times, resulting in a remainder of 476.
Write down 7 as next digit of the result. 
Result so far: 977.0
The remainder is 476 after subtracting 5649 from 6125.
Bring next digit (1) of the dividend behind the 476 and repeat the process: 4761 / 807

On to step 7:
If we divide 4761 by 807, we get 5 and a remainder of 726.
The next digit of our result is 5. 
Result so far: 9775.0
If we take 4035 away from 4761, we end up with 726.
Fetch the next digit (6) from the dividend, attach it to 726 and continue: 7266 / 807

Moving on to step 8:
If we divide 7266 by 807, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 97759.0
The remainder is 3 after subtracting 7263 from 7266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
If we divide 30 by 807, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 97759.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
807 goes into 300 0 times with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 97759.0
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

In conclusion, the division gives 97759.0 with a balance of 0.3.
