12136885 ÷ 842 
We want to figure out the number of times 12136885 can be divided by 842.

Going ahead to step 1:
The number 842 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 842

Let's proceed to step 2:
842 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.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 842

On to step 3:
121 divided by 842 is 0 with a remainder of 121.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 121, we end up with 121.
Take the next digit (3) from the dividend and append it to 121, then repeat: 1213 / 842

Advancing to step 4:
The number 842 fits into 1213 1 times, leaving a remainder of 371.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 842 away from 1213, we end up with 371.
Bring next digit (6) of the dividend behind the 371 and repeat the process: 3716 / 842

Let's proceed to step 5:
If we divide 3716 by 842, we get 4 and a remainder of 348.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 3368 from 3716, we get 348.
Fetch the next digit (8) from the dividend, attach it to 348 and continue: 3488 / 842

Advancing to step 6:
If we divide 3488 by 842, we get 4 and a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 144.0
The remainder is 120 after subtracting 3368 from 3488.
Fetch the next digit (8) from the dividend, attach it to 120 and continue: 1208 / 842

Step 7:
842 goes into 1208 1 times with a remainder of 366.
Write down 1 as next digit of the result. 
Result so far: 1441.0
Subtracting 842 from 1208 leaves us with 366.
Include the next digit (5) from the dividend after 366, then repeat: 3665 / 842

Moving on to step 8:
3665 divided by 842 is 4 with a remainder of 297.
The number 4 becomes the next digit in our result. 
Result so far: 14414.0
Subtract 3368 from 3665 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Advancing to step 9:
842 goes into 2970 3 times with a remainder of 444.
Use 3 as the next digit of our solution. 
Result so far: 14414.3
If we take 2526 away from 2970, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Advancing to step 10:
842 can be fit into 4440 5 times, resulting in a remainder of 230.
The next digit of our result is 5. 
Result so far: 14414.35
Subtract 4210 from 4440 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 11:
842 can be fit into 2300 2 times, resulting in a remainder of 616.
Record the quotient 2 as the next digit in the result. 
Result so far: 14414.352
Subtracting 1684 from 2300 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 12:
842 can be fit into 6160 7 times, resulting in a remainder of 266.
Record the quotient 7 as the next digit in the result. 
Result so far: 14414.3527
The remainder is 266 after subtracting 5894 from 6160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 13:
2660 divided by 842 is 3 with a remainder of 134.
Write down 3 as next digit of the result. 
Result so far: 14414.35273
If we subtract 2526 from 2660, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 14:
1340 divided by 842 is 1 with a remainder of 498.
Write down 1 as next digit of the result. 
Result so far: 14414.352731
Subtract 842 from 1340 to get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

On to step 15:
842 can be fit into 4980 5 times, resulting in a remainder of 770.
Put 5 as the next digit of the answer. 
Result so far: 14414.3527315
Subtracting 4210 from 4980 leaves us with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Going ahead to step 16:
842 can be fit into 7700 9 times, resulting in a remainder of 122.
Use 9 as the next digit of our solution. 
Result so far: 14414.35273159
If we take 7578 away from 7700, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

After the division, we end up with 14414.35273159 and a remainder of 1.22e-07.
