We look at the division of 66469592 by 768 
We want to figure out the number of times 66469592 can be divided by 768.

Advancing to step 1:
768 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 768

Advancing to step 2:
The number 768 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 768

On to step 3:
The number 768 fits into 664 0 times, leaving a remainder of 664.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 664, we get 664.
Take the next digit (6) from the dividend and append it to 664, then repeat: 6646 / 768

Going ahead to step 4:
768 goes into 6646 8 times with a remainder of 502.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 6144 away from 6646, we end up with 502.
Bring next digit (9) of the dividend behind the 502 and repeat the process: 5029 / 768

Going ahead to step 5:
768 can be fit into 5029 6 times, resulting in a remainder of 421.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtracting 4608 from 5029 leaves us with 421.
Append the next digit (5) from the dividend to 421 and continue with: 4215 / 768

Let's proceed to step 6:
4215 divided by 768 is 5 with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 865.0
Deduct 3840 from 4215 and we're left with 375.
Take the next digit (9) from the dividend and append it to 375, then repeat: 3759 / 768

Going ahead to step 7:
If we divide 3759 by 768, we get 4 and a remainder of 687.
Use 4 as the next digit of our solution. 
Result so far: 8654.0
If we subtract 3072 from 3759, we get 687.
Bring next digit (2) of the dividend behind the 687 and repeat the process: 6872 / 768

Moving on to step 8:
When dividing 6872 by 768, we get 8 with a remainder of 728.
Write down 8 as next digit of the result. 
Result so far: 86548.0
If we subtract 6144 from 6872, we get 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

On to step 9:
768 can be fit into 7280 9 times, resulting in a remainder of 368.
Put 9 as the next digit of the answer. 
Result so far: 86548.9
Subtracting 6912 from 7280 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 10:
The number 768 fits into 3680 4 times, leaving a remainder of 608.
Use 4 as the next digit of our solution. 
Result so far: 86548.94
Subtract 3072 from 3680 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 11:
768 goes into 6080 7 times with a remainder of 704.
Write down 7 as next digit of the result. 
Result so far: 86548.947
If we subtract 5376 from 6080, we get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Step 12:
When dividing 7040 by 768, we get 9 with a remainder of 128.
The number 9 becomes the next digit in our result. 
Result so far: 86548.9479
Deduct 6912 from 7040 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 13:
The number 768 fits into 1280 1 times, leaving a remainder of 512.
Use 1 as the next digit of our solution. 
Result so far: 86548.94791
If we subtract 768 from 1280, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 14:
768 can be fit into 5120 6 times, resulting in a remainder of 512.
Use 6 as the next digit of our solution. 
Result so far: 86548.947916
If we take 4608 away from 5120, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 15:
When dividing 5120 by 768, we get 6 with a remainder of 512.
The next digit of our result is 6. 
Result so far: 86548.9479166
If we take 4608 away from 5120, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

The final outcome is 86548.9479166, with a leftover of 5.12e-06.
