81987310 ÷ 768 
Let's see how many times 768 fits into 81987310.

Step 1:
768 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 768

Advancing to step 2:
81 divided by 768 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 768

Advancing to step 3:
819 divided by 768 is 1 with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 768 from 819 leaves us with 51.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 768

Going ahead to step 4:
When dividing 518 by 768, we get 0 with a remainder of 518.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 518 after subtracting 0 from 518.
Grab the next digit (7) from the dividend, add it to 518, then carry on: 5187 / 768

Going ahead to step 5:
If we divide 5187 by 768, we get 6 and a remainder of 579.
Write down 6 as next digit of the result. 
Result so far: 106.0
Subtracting 4608 from 5187 leaves us with 579.
Include the next digit (3) from the dividend after 579, then repeat: 5793 / 768

Moving on to step 6:
When dividing 5793 by 768, we get 7 with a remainder of 417.
The next digit of our result is 7. 
Result so far: 1067.0
Subtracting 5376 from 5793 leaves us with 417.
Grab the next digit (1) from the dividend, add it to 417, then carry on: 4171 / 768

Going ahead to step 7:
When dividing 4171 by 768, we get 5 with a remainder of 331.
Use 5 as the next digit of our solution. 
Result so far: 10675.0
Deduct 3840 from 4171 and we're left with 331.
Take the next digit (0) from the dividend and append it to 331, then repeat: 3310 / 768

On to step 8:
768 can be fit into 3310 4 times, resulting in a remainder of 238.
Write down 4 as next digit of the result. 
Result so far: 106754.0
Deduct 3072 from 3310 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 9:
The number 768 fits into 2380 3 times, leaving a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 106754.3
If we subtract 2304 from 2380, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
760 divided by 768 is 0 with a remainder of 760.
Record the quotient 0 as the next digit in the result. 
Result so far: 106754.3
Subtracting 0 from 760 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 11:
768 goes into 7600 9 times with a remainder of 688.
Write down 9 as next digit of the result. 
Result so far: 106754.309
Deduct 6912 from 7600 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Step 12:
768 can be fit into 6880 8 times, resulting in a remainder of 736.
The number 8 becomes the next digit in our result. 
Result so far: 106754.3098
Subtract 6144 from 6880 to get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Going ahead to step 13:
7360 divided by 768 is 9 with a remainder of 448.
Write down 9 as next digit of the result. 
Result so far: 106754.30989
Deduct 6912 from 7360 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 14:
768 goes into 4480 5 times with a remainder of 640.
Write down 5 as next digit of the result. 
Result so far: 106754.309895
If we take 3840 away from 4480, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 15:
When dividing 6400 by 768, we get 8 with a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 106754.3098958
If we take 6144 away from 6400, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 16:
The number 768 fits into 2560 3 times, leaving a remainder of 256.
The next digit of our result is 3. 
Result so far: 106754.30989583
If we take 2304 away from 2560, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

In conclusion, the division gives 106754.30989583 with a balance of 2.56e-07.
