We look at the division of 12120291 by 889 
We want to figure out the number of times 12120291 can be divided by 889.

Going ahead to step 1:
1 divided by 889 is 0 with 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.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 889

Advancing to step 2:
889 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 889

Step 3:
The number 889 fits into 121 0 times, leaving a remainder of 121.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 121, we get 121.
Fetch the next digit (2) from the dividend, attach it to 121 and continue: 1212 / 889

Step 4:
889 can be fit into 1212 1 times, resulting in a remainder of 323.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 889 from 1212 to get 323.
Include the next digit (0) from the dividend after 323, then repeat: 3230 / 889

On to step 5:
If we divide 3230 by 889, we get 3 and a remainder of 563.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 2667 from 3230, we get 563.
Fetch the next digit (2) from the dividend, attach it to 563 and continue: 5632 / 889

On to step 6:
889 can be fit into 5632 6 times, resulting in a remainder of 298.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
Subtracting 5334 from 5632 leaves us with 298.
Fetch the next digit (9) from the dividend, attach it to 298 and continue: 2989 / 889

On to step 7:
If we divide 2989 by 889, we get 3 and a remainder of 322.
Write down 3 as next digit of the result. 
Result so far: 1363.0
Subtracting 2667 from 2989 leaves us with 322.
Take the next digit (1) from the dividend and append it to 322, then repeat: 3221 / 889

Going ahead to step 8:
889 goes into 3221 3 times with a remainder of 554.
The next digit of our result is 3. 
Result so far: 13633.0
Deduct 2667 from 3221 and we're left with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

On to step 9:
889 can be fit into 5540 6 times, resulting in a remainder of 206.
The number 6 becomes the next digit in our result. 
Result so far: 13633.6
If we subtract 5334 from 5540, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 10:
889 goes into 2060 2 times with a remainder of 282.
The number 2 becomes the next digit in our result. 
Result so far: 13633.62
If we subtract 1778 from 2060, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 11:
When dividing 2820 by 889, we get 3 with a remainder of 153.
The next digit of our result is 3. 
Result so far: 13633.623
Subtracting 2667 from 2820 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 12:
889 can be fit into 1530 1 times, resulting in a remainder of 641.
Put 1 as the next digit of the answer. 
Result so far: 13633.6231
Subtracting 889 from 1530 leaves us with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Step 13:
If we divide 6410 by 889, we get 7 and a remainder of 187.
Record the quotient 7 as the next digit in the result. 
Result so far: 13633.62317
Subtract 6223 from 6410 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 14:
The number 889 fits into 1870 2 times, leaving a remainder of 92.
Use 2 as the next digit of our solution. 
Result so far: 13633.623172
The remainder is 92 after subtracting 1778 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 15:
889 goes into 920 1 times with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 13633.6231721
Subtract 889 from 920 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 16:
If we divide 310 by 889, we get 0 and a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 13633.6231721
The remainder is 310 after subtracting 0 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

After the division, we end up with 13633.6231721 and a remainder of 3.1e-07.
