We look at the division of 12999996 by 786 
We're looking to find how many times 786 goes into 12999996.

Moving on to step 1:
When dividing 1 by 786, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
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 / 786

Let's proceed to step 2:
If we divide 12 by 786, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 786

Step 3:
786 goes into 129 0 times with a remainder of 129.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 129 after subtracting 0 from 129.
Append the next digit (9) from the dividend to 129 and continue with: 1299 / 786

Moving on to step 4:
If we divide 1299 by 786, we get 1 and a remainder of 513.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 786 from 1299 to get 513.
Fetch the next digit (9) from the dividend, attach it to 513 and continue: 5139 / 786

On to step 5:
When dividing 5139 by 786, we get 6 with a remainder of 423.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 4716 from 5139, we get 423.
Fetch the next digit (9) from the dividend, attach it to 423 and continue: 4239 / 786

Step 6:
The number 786 fits into 4239 5 times, leaving a remainder of 309.
Use 5 as the next digit of our solution. 
Result so far: 165.0
Subtract 3930 from 4239 to get 309.
Include the next digit (9) from the dividend after 309, then repeat: 3099 / 786

Moving on to step 7:
If we divide 3099 by 786, we get 3 and a remainder of 741.
Put 3 as the next digit of the answer. 
Result so far: 1653.0
The remainder is 741 after subtracting 2358 from 3099.
Include the next digit (6) from the dividend after 741, then repeat: 7416 / 786

Moving on to step 8:
7416 divided by 786 is 9 with a remainder of 342.
The number 9 becomes the next digit in our result. 
Result so far: 16539.0
Subtract 7074 from 7416 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Advancing to step 9:
If we divide 3420 by 786, we get 4 and a remainder of 276.
Write down 4 as next digit of the result. 
Result so far: 16539.4
The remainder is 276 after subtracting 3144 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 10:
The number 786 fits into 2760 3 times, leaving a remainder of 402.
Use 3 as the next digit of our solution. 
Result so far: 16539.43
If we subtract 2358 from 2760, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 11:
786 can be fit into 4020 5 times, resulting in a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 16539.435
Subtracting 3930 from 4020 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
If we divide 900 by 786, we get 1 and a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 16539.4351
If we subtract 786 from 900, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 13:
When dividing 1140 by 786, we get 1 with a remainder of 354.
Use 1 as the next digit of our solution. 
Result so far: 16539.43511
Deduct 786 from 1140 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Our division results in 16539.43511 with a remaining 0.000354.
