Let's divide 87009239 by 768
We're looking to find how many times 768 goes into 87009239.

Moving on to step 1:
The number 768 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 768

Going ahead to step 2:
768 goes into 87 0 times with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Take the next digit (0) from the dividend and append it to 87, then repeat: 870 / 768

Step 3:
If we divide 870 by 768, we get 1 and a remainder of 102.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 768 from 870, we get 102.
Grab the next digit (0) from the dividend, add it to 102, then carry on: 1020 / 768

Let's proceed to step 4:
If we divide 1020 by 768, we get 1 and a remainder of 252.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 768 away from 1020, we end up with 252.
Include the next digit (9) from the dividend after 252, then repeat: 2529 / 768

Step 5:
768 goes into 2529 3 times with a remainder of 225.
Write down 3 as next digit of the result. 
Result so far: 113.0
Deduct 2304 from 2529 and we're left with 225.
Include the next digit (2) from the dividend after 225, then repeat: 2252 / 768

Going ahead to step 6:
768 can be fit into 2252 2 times, resulting in a remainder of 716.
Write down 2 as next digit of the result. 
Result so far: 1132.0
Deduct 1536 from 2252 and we're left with 716.
Grab the next digit (3) from the dividend, add it to 716, then carry on: 7163 / 768

Moving on to step 7:
The number 768 fits into 7163 9 times, leaving a remainder of 251.
Use 9 as the next digit of our solution. 
Result so far: 11329.0
If we take 6912 away from 7163, we end up with 251.
Include the next digit (9) from the dividend after 251, then repeat: 2519 / 768

Let's proceed to step 8:
When dividing 2519 by 768, we get 3 with a remainder of 215.
Use 3 as the next digit of our solution. 
Result so far: 113293.0
If we take 2304 away from 2519, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 9:
The number 768 fits into 2150 2 times, leaving a remainder of 614.
Put 2 as the next digit of the answer. 
Result so far: 113293.2
Subtract 1536 from 2150 to get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Going ahead to step 10:
6140 divided by 768 is 7 with a remainder of 764.
The next digit of our result is 7. 
Result so far: 113293.27
Subtract 5376 from 6140 to get 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Moving on to step 11:
When dividing 7640 by 768, we get 9 with a remainder of 728.
Use 9 as the next digit of our solution. 
Result so far: 113293.279
If we take 6912 away from 7640, we end up with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Advancing to step 12:
7280 divided by 768 is 9 with a remainder of 368.
The number 9 becomes the next digit in our result. 
Result so far: 113293.2799
Subtract 6912 from 7280 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final outcome is 113293.2799, with a leftover of 0.00368.
