Let's divide 12806985 by 873
We want to figure out the number of times 12806985 can be divided by 873.

Advancing to step 1:
1 divided by 873 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 873

Moving on to step 2:
When dividing 12 by 873, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 873

On to step 3:
When dividing 128 by 873, we get 0 with a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 128, we end up with 128.
Bring next digit (0) of the dividend behind the 128 and repeat the process: 1280 / 873

Going ahead to step 4:
873 goes into 1280 1 times with a remainder of 407.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 873 from 1280 to get 407.
Bring next digit (6) of the dividend behind the 407 and repeat the process: 4076 / 873

Going ahead to step 5:
873 goes into 4076 4 times with a remainder of 584.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 3492 from 4076 and we're left with 584.
Grab the next digit (9) from the dividend, add it to 584, then carry on: 5849 / 873

Advancing to step 6:
The number 873 fits into 5849 6 times, leaving a remainder of 611.
Use 6 as the next digit of our solution. 
Result so far: 146.0
Subtract 5238 from 5849 to get 611.
Include the next digit (8) from the dividend after 611, then repeat: 6118 / 873

Going ahead to step 7:
873 goes into 6118 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 1467.0
Subtracting 6111 from 6118 leaves us with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 873

Going ahead to step 8:
873 goes into 75 0 times with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 14670.0
If we take 0 away from 75, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 9:
873 can be fit into 750 0 times, resulting in a remainder of 750.
Record the quotient 0 as the next digit in the result. 
Result so far: 14670.0
If we subtract 0 from 750, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 10:
The number 873 fits into 7500 8 times, leaving a remainder of 516.
Use 8 as the next digit of our solution. 
Result so far: 14670.08
If we subtract 6984 from 7500, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 11:
The number 873 fits into 5160 5 times, leaving a remainder of 795.
Put 5 as the next digit of the answer. 
Result so far: 14670.085
Subtracting 4365 from 5160 leaves us with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Step 12:
If we divide 7950 by 873, we get 9 and a remainder of 93.
Record the quotient 9 as the next digit in the result. 
Result so far: 14670.0859
Subtract 7857 from 7950 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 13:
873 can be fit into 930 1 times, resulting in a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 14670.08591
The remainder is 57 after subtracting 873 from 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 14:
The number 873 fits into 570 0 times, leaving a remainder of 570.
The next digit of our result is 0. 
Result so far: 14670.08591
If we take 0 away from 570, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

On to step 15:
If we divide 5700 by 873, we get 6 and a remainder of 462.
Put 6 as the next digit of the answer. 
Result so far: 14670.0859106
Subtract 5238 from 5700 to get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 16:
873 can be fit into 4620 5 times, resulting in a remainder of 255.
The number 5 becomes the next digit in our result. 
Result so far: 14670.08591065
If we subtract 4365 from 4620, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

The final result is 14670.08591065 with a remainder of 2.55e-07.
