12148431 divided by 104 
We want to divide 12148431 by 104.

Let's proceed to step 1:
If we divide 1 by 104, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 104

On to step 2:
If we divide 12 by 104, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 104

Advancing to step 3:
If we divide 121 by 104, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 104 away from 121, we end up with 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 104

Advancing to step 4:
The number 104 fits into 174 1 times, leaving a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 104 away from 174, we end up with 70.
Include the next digit (8) from the dividend after 70, then repeat: 708 / 104

Moving on to step 5:
When dividing 708 by 104, we get 6 with a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Subtract 624 from 708 to get 84.
Include the next digit (4) from the dividend after 84, then repeat: 844 / 104

Going ahead to step 6:
The number 104 fits into 844 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1168.0
Subtracting 832 from 844 leaves us with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 104

Advancing to step 7:
If we divide 123 by 104, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 11681.0
Deduct 104 from 123 and we're left with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 104

Step 8:
The number 104 fits into 191 1 times, leaving a remainder of 87.
Write down 1 as next digit of the result. 
Result so far: 116811.0
Subtracting 104 from 191 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 9:
104 goes into 870 8 times with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 116811.8
If we subtract 832 from 870, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
If we divide 380 by 104, we get 3 and a remainder of 68.
The next digit of our result is 3. 
Result so far: 116811.83
Subtracting 312 from 380 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 11:
104 goes into 680 6 times with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 116811.836
Deduct 624 from 680 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
104 can be fit into 560 5 times, resulting in a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 116811.8365
Deduct 520 from 560 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
104 can be fit into 400 3 times, resulting in a remainder of 88.
The number 3 becomes the next digit in our result. 
Result so far: 116811.83653
If we subtract 312 from 400, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 14:
880 divided by 104 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 116811.836538
If we subtract 832 from 880, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 15:
The number 104 fits into 480 4 times, leaving a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 116811.8365384
Deduct 416 from 480 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 16:
640 divided by 104 is 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 116811.83653846
If we take 624 away from 640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 116811.83653846 with a remainder of 1.6e-08.
