We divide 12808531 by 853
We're looking to find how many times 853 goes into 12808531.

Step 1:
853 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 853

On to step 2:
853 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 853

Step 3:
853 goes into 128 0 times with a remainder of 128.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 128 to get 128.
Append the next digit (0) from the dividend to 128 and continue with: 1280 / 853

On to step 4:
1280 divided by 853 is 1 with a remainder of 427.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 853 from 1280 to get 427.
Take the next digit (8) from the dividend and append it to 427, then repeat: 4278 / 853

Going ahead to step 5:
If we divide 4278 by 853, we get 5 and a remainder of 13.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 4265 from 4278 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 853

Going ahead to step 6:
853 can be fit into 135 0 times, resulting in a remainder of 135.
The next digit of our result is 0. 
Result so far: 150.0
If we subtract 0 from 135, we get 135.
Include the next digit (3) from the dividend after 135, then repeat: 1353 / 853

Step 7:
853 goes into 1353 1 times with a remainder of 500.
Write down 1 as next digit of the result. 
Result so far: 1501.0
Subtracting 853 from 1353 leaves us with 500.
Grab the next digit (1) from the dividend, add it to 500, then carry on: 5001 / 853

Step 8:
The number 853 fits into 5001 5 times, leaving a remainder of 736.
Put 5 as the next digit of the answer. 
Result so far: 15015.0
If we take 4265 away from 5001, we end up with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Going ahead to step 9:
When dividing 7360 by 853, we get 8 with a remainder of 536.
The next digit of our result is 8. 
Result so far: 15015.8
Subtracting 6824 from 7360 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Let's proceed to step 10:
853 goes into 5360 6 times with a remainder of 242.
The next digit of our result is 6. 
Result so far: 15015.86
If we take 5118 away from 5360, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Moving on to step 11:
853 goes into 2420 2 times with a remainder of 714.
Record the quotient 2 as the next digit in the result. 
Result so far: 15015.862
If we subtract 1706 from 2420, we get 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Advancing to step 12:
If we divide 7140 by 853, we get 8 and a remainder of 316.
Write down 8 as next digit of the result. 
Result so far: 15015.8628
Subtracting 6824 from 7140 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 13:
The number 853 fits into 3160 3 times, leaving a remainder of 601.
Record the quotient 3 as the next digit in the result. 
Result so far: 15015.86283
Subtract 2559 from 3160 to get 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Moving on to step 14:
6010 divided by 853 is 7 with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 15015.862837
Subtracting 5971 from 6010 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 15:
If we divide 390 by 853, we get 0 and a remainder of 390.
Record the quotient 0 as the next digit in the result. 
Result so far: 15015.862837
If we subtract 0 from 390, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 16:
3900 divided by 853 is 4 with a remainder of 488.
Put 4 as the next digit of the answer. 
Result so far: 15015.86283704
Deduct 3412 from 3900 and we're left 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.

The quotient of the division is 15015.86283704, and the remainder is 4.88e-07.
