12984534 ÷ 846 
Our goal is to divide 12984534 by 846.

On to step 1:
When dividing 1 by 846, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 846

Advancing to step 2:
846 goes into 12 0 times 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.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 846

Let's proceed to step 3:
If we divide 129 by 846, we get 0 and a remainder of 129.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 129, we end up with 129.
Fetch the next digit (8) from the dividend, attach it to 129 and continue: 1298 / 846

Moving on to step 4:
The number 846 fits into 1298 1 times, leaving a remainder of 452.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 452 after subtracting 846 from 1298.
Fetch the next digit (4) from the dividend, attach it to 452 and continue: 4524 / 846

Moving on to step 5:
4524 divided by 846 is 5 with a remainder of 294.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 4230 from 4524 and we're left with 294.
Include the next digit (5) from the dividend after 294, then repeat: 2945 / 846

Going ahead to step 6:
2945 divided by 846 is 3 with a remainder of 407.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Deduct 2538 from 2945 and we're left with 407.
Append the next digit (3) from the dividend to 407 and continue with: 4073 / 846

On to step 7:
846 can be fit into 4073 4 times, resulting in a remainder of 689.
Use 4 as the next digit of our solution. 
Result so far: 1534.0
Deduct 3384 from 4073 and we're left with 689.
Grab the next digit (4) from the dividend, add it to 689, then carry on: 6894 / 846

On to step 8:
846 goes into 6894 8 times with a remainder of 126.
Use 8 as the next digit of our solution. 
Result so far: 15348.0
Subtract 6768 from 6894 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 9:
846 can be fit into 1260 1 times, resulting in a remainder of 414.
The number 1 becomes the next digit in our result. 
Result so far: 15348.1
Subtract 846 from 1260 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 10:
If we divide 4140 by 846, we get 4 and a remainder of 756.
Use 4 as the next digit of our solution. 
Result so far: 15348.14
Subtracting 3384 from 4140 leaves us with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Step 11:
If we divide 7560 by 846, we get 8 and a remainder of 792.
Use 8 as the next digit of our solution. 
Result so far: 15348.148
If we subtract 6768 from 7560, we get 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Moving on to step 12:
When dividing 7920 by 846, we get 9 with a remainder of 306.
The number 9 becomes the next digit in our result. 
Result so far: 15348.1489
Subtracting 7614 from 7920 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 13:
3060 divided by 846 is 3 with a remainder of 522.
Put 3 as the next digit of the answer. 
Result so far: 15348.14893
The remainder is 522 after subtracting 2538 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Let's proceed to step 14:
846 goes into 5220 6 times with a remainder of 144.
Write down 6 as next digit of the result. 
Result so far: 15348.148936
The remainder is 144 after subtracting 5076 from 5220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 15:
846 goes into 1440 1 times with a remainder of 594.
Write down 1 as next digit of the result. 
Result so far: 15348.1489361
If we take 846 away from 1440, we end up with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Going ahead to step 16:
846 can be fit into 5940 7 times, resulting in a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 15348.14893617
If we subtract 5922 from 5940, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 15348.14893617 with a balance of 1.8e-08.
