Let's divide 66813632 by 853
We want to divide 66813632 by 853.

Advancing to step 1:
6 divided by 853 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 853

On to step 2:
853 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 853

Advancing to step 3:
The number 853 fits into 668 0 times, leaving a remainder of 668.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 668 to get 668.
Include the next digit (1) from the dividend after 668, then repeat: 6681 / 853

Let's proceed to step 4:
The number 853 fits into 6681 7 times, leaving a remainder of 710.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 5971 from 6681 and we're left with 710.
Include the next digit (3) from the dividend after 710, then repeat: 7103 / 853

Advancing to step 5:
7103 divided by 853 is 8 with a remainder of 279.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtract 6824 from 7103 to get 279.
Bring next digit (6) of the dividend behind the 279 and repeat the process: 2796 / 853

Moving on to step 6:
853 can be fit into 2796 3 times, resulting in a remainder of 237.
Write down 3 as next digit of the result. 
Result so far: 783.0
Deduct 2559 from 2796 and we're left with 237.
Bring next digit (3) of the dividend behind the 237 and repeat the process: 2373 / 853

Let's proceed to step 7:
853 can be fit into 2373 2 times, resulting in a remainder of 667.
The next digit of our result is 2. 
Result so far: 7832.0
Subtract 1706 from 2373 to get 667.
Append the next digit (2) from the dividend to 667 and continue with: 6672 / 853

Going ahead to step 8:
853 can be fit into 6672 7 times, resulting in a remainder of 701.
Put 7 as the next digit of the answer. 
Result so far: 78327.0
If we subtract 5971 from 6672, we get 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Advancing to step 9:
When dividing 7010 by 853, we get 8 with a remainder of 186.
The next digit of our result is 8. 
Result so far: 78327.8
Subtracting 6824 from 7010 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 10:
When dividing 1860 by 853, we get 2 with a remainder of 154.
Put 2 as the next digit of the answer. 
Result so far: 78327.82
If we subtract 1706 from 1860, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 11:
853 can be fit into 1540 1 times, resulting in a remainder of 687.
Write down 1 as next digit of the result. 
Result so far: 78327.821
If we subtract 853 from 1540, we get 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Moving on to step 12:
When dividing 6870 by 853, we get 8 with a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 78327.8218
Deduct 6824 from 6870 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
When dividing 460 by 853, we get 0 with a remainder of 460.
Put 0 as the next digit of the answer. 
Result so far: 78327.8218
If we take 0 away from 460, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 14:
If we divide 4600 by 853, we get 5 and a remainder of 335.
Record the quotient 5 as the next digit in the result. 
Result so far: 78327.821805
Subtracting 4265 from 4600 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 15:
The number 853 fits into 3350 3 times, leaving a remainder of 791.
Use 3 as the next digit of our solution. 
Result so far: 78327.8218053
If we subtract 2559 from 3350, we get 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

Advancing to step 16:
853 goes into 7910 9 times with a remainder of 233.
Record the quotient 9 as the next digit in the result. 
Result so far: 78327.82180539
Subtract 7677 from 7910 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

After the division, we end up with 78327.82180539 and a remainder of 2.33e-07.
