We're dividing 12718130 by 891 
We want to figure out the number of times 12718130 can be divided by 891.

On to step 1:
891 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
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 891

Let's proceed to step 2:
12 divided by 891 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 891

Moving on to step 3:
127 divided by 891 is 0 with a remainder of 127.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 127, we get 127.
Grab the next digit (1) from the dividend, add it to 127, then carry on: 1271 / 891

Moving on to step 4:
891 can be fit into 1271 1 times, resulting in a remainder of 380.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 380 after subtracting 891 from 1271.
Fetch the next digit (8) from the dividend, attach it to 380 and continue: 3808 / 891

On to step 5:
891 can be fit into 3808 4 times, resulting in a remainder of 244.
The next digit of our result is 4. 
Result so far: 14.0
If we take 3564 away from 3808, we end up with 244.
Append the next digit (1) from the dividend to 244 and continue with: 2441 / 891

Step 6:
891 can be fit into 2441 2 times, resulting in a remainder of 659.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
Deduct 1782 from 2441 and we're left with 659.
Append the next digit (3) from the dividend to 659 and continue with: 6593 / 891

Step 7:
6593 divided by 891 is 7 with a remainder of 356.
The number 7 becomes the next digit in our result. 
Result so far: 1427.0
If we take 6237 away from 6593, we end up with 356.
Include the next digit (0) from the dividend after 356, then repeat: 3560 / 891

Going ahead to step 8:
891 can be fit into 3560 3 times, resulting in a remainder of 887.
The next digit of our result is 3. 
Result so far: 14273.0
If we take 2673 away from 3560, we end up with 887.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8870, and continue the process.

Step 9:
8870 divided by 891 is 9 with a remainder of 851.
Record the quotient 9 as the next digit in the result. 
Result so far: 14273.9
Subtracting 8019 from 8870 leaves us with 851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

Going ahead to step 10:
8510 divided by 891 is 9 with a remainder of 491.
Use 9 as the next digit of our solution. 
Result so far: 14273.99
Subtract 8019 from 8510 to get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

The final outcome is 14273.99, with a leftover of 0.491.
