We look at the division of 66815251 by 848 
Let's see how many times 848 fits into 66815251.

Moving on to step 1:
If we divide 6 by 848, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 848

Step 2:
848 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 848

Step 3:
The number 848 fits into 668 0 times, leaving a remainder of 668.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 668 after subtracting 0 from 668.
Append the next digit (1) from the dividend to 668 and continue with: 6681 / 848

On to step 4:
The number 848 fits into 6681 7 times, leaving a remainder of 745.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 745 after subtracting 5936 from 6681.
Fetch the next digit (5) from the dividend, attach it to 745 and continue: 7455 / 848

Moving on to step 5:
The number 848 fits into 7455 8 times, leaving a remainder of 671.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 6784 from 7455 and we're left with 671.
Bring next digit (2) of the dividend behind the 671 and repeat the process: 6712 / 848

Going ahead to step 6:
When dividing 6712 by 848, we get 7 with a remainder of 776.
The next digit of our result is 7. 
Result so far: 787.0
The remainder is 776 after subtracting 5936 from 6712.
Include the next digit (5) from the dividend after 776, then repeat: 7765 / 848

Moving on to step 7:
848 goes into 7765 9 times with a remainder of 133.
Put 9 as the next digit of the answer. 
Result so far: 7879.0
Subtract 7632 from 7765 to get 133.
Append the next digit (1) from the dividend to 133 and continue with: 1331 / 848

Advancing to step 8:
When dividing 1331 by 848, we get 1 with a remainder of 483.
Use 1 as the next digit of our solution. 
Result so far: 78791.0
Deduct 848 from 1331 and we're left with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

On to step 9:
If we divide 4830 by 848, we get 5 and a remainder of 590.
Put 5 as the next digit of the answer. 
Result so far: 78791.5
Subtracting 4240 from 4830 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

On to step 10:
The number 848 fits into 5900 6 times, leaving a remainder of 812.
Use 6 as the next digit of our solution. 
Result so far: 78791.56
Deduct 5088 from 5900 and we're left with 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Step 11:
8120 divided by 848 is 9 with a remainder of 488.
The next digit of our result is 9. 
Result so far: 78791.569
If we take 7632 away from 8120, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 12:
When dividing 4880 by 848, we get 5 with a remainder of 640.
The number 5 becomes the next digit in our result. 
Result so far: 78791.5695
Subtracting 4240 from 4880 leaves us 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 13:
The number 848 fits into 6400 7 times, leaving a remainder of 464.
Record the quotient 7 as the next digit in the result. 
Result so far: 78791.56957
Subtract 5936 from 6400 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 14:
The number 848 fits into 4640 5 times, leaving a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 78791.569575
If we take 4240 away from 4640, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 15:
When dividing 4000 by 848, we get 4 with a remainder of 608.
Put 4 as the next digit of the answer. 
Result so far: 78791.5695754
Subtract 3392 from 4000 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.

Let's proceed to step 16:
6080 divided by 848 is 7 with a remainder of 144.
Write down 7 as next digit of the result. 
Result so far: 78791.56957547
If we subtract 5936 from 6080, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The quotient of the division is 78791.56957547, and the remainder is 1.44e-07.
