Let's divide 66549171 by 853
Let's see how many times 853 fits into 66549171.

Advancing to step 1:
853 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 853

Going ahead to step 2:
When dividing 66 by 853, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (5) from the dividend, add it to 66, then carry on: 665 / 853

Step 3:
665 divided by 853 is 0 with a remainder of 665.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 665 leaves us with 665.
Fetch the next digit (4) from the dividend, attach it to 665 and continue: 6654 / 853

Step 4:
If we divide 6654 by 853, we get 7 and a remainder of 683.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 5971 from 6654, we get 683.
Append the next digit (9) from the dividend to 683 and continue with: 6839 / 853

On to step 5:
853 can be fit into 6839 8 times, resulting in a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Subtracting 6824 from 6839 leaves us with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 853

Step 6:
When dividing 151 by 853, we get 0 with a remainder of 151.
The next digit of our result is 0. 
Result so far: 780.0
If we take 0 away from 151, we end up with 151.
Bring next digit (7) of the dividend behind the 151 and repeat the process: 1517 / 853

On to step 7:
853 goes into 1517 1 times with a remainder of 664.
The next digit of our result is 1. 
Result so far: 7801.0
If we subtract 853 from 1517, we get 664.
Fetch the next digit (1) from the dividend, attach it to 664 and continue: 6641 / 853

On to step 8:
853 goes into 6641 7 times with a remainder of 670.
Write down 7 as next digit of the result. 
Result so far: 78017.0
If we take 5971 away from 6641, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 9:
853 can be fit into 6700 7 times, resulting in a remainder of 729.
The number 7 becomes the next digit in our result. 
Result so far: 78017.7
Subtract 5971 from 6700 to get 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

On to step 10:
853 goes into 7290 8 times with a remainder of 466.
Write down 8 as next digit of the result. 
Result so far: 78017.78
If we subtract 6824 from 7290, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Let's proceed to step 11:
853 goes into 4660 5 times with a remainder of 395.
Put 5 as the next digit of the answer. 
Result so far: 78017.785
Subtract 4265 from 4660 to get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 12:
853 goes into 3950 4 times with a remainder of 538.
Write down 4 as next digit of the result. 
Result so far: 78017.7854
The remainder is 538 after subtracting 3412 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Going ahead to step 13:
853 can be fit into 5380 6 times, resulting in a remainder of 262.
The number 6 becomes the next digit in our result. 
Result so far: 78017.78546
If we subtract 5118 from 5380, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 14:
853 goes into 2620 3 times with a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 78017.785463
Subtract 2559 from 2620 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 15:
853 goes into 610 0 times with a remainder of 610.
Record the quotient 0 as the next digit in the result. 
Result so far: 78017.785463
Subtracting 0 from 610 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Advancing to step 16:
853 can be fit into 6100 7 times, resulting in a remainder of 129.
Put 7 as the next digit of the answer. 
Result so far: 78017.78546307
Subtract 5971 from 6100 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

After the division, we end up with 78017.78546307 and a remainder of 1.29e-07.
