We're dividing 12658538 by 784 
We want to divide 12658538 by 784.

On to step 1:
1 divided by 784 is 0 with 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.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 784

On to step 2:
When dividing 12 by 784, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 784

Let's proceed to step 3:
126 divided by 784 is 0 with a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 126 to get 126.
Include the next digit (5) from the dividend after 126, then repeat: 1265 / 784

Advancing to step 4:
When dividing 1265 by 784, we get 1 with a remainder of 481.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 784 from 1265 leaves us with 481.
Grab the next digit (8) from the dividend, add it to 481, then carry on: 4818 / 784

Advancing to step 5:
If we divide 4818 by 784, we get 6 and a remainder of 114.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 4704 from 4818, we get 114.
Include the next digit (5) from the dividend after 114, then repeat: 1145 / 784

On to step 6:
784 goes into 1145 1 times with a remainder of 361.
Write down 1 as next digit of the result. 
Result so far: 161.0
Subtracting 784 from 1145 leaves us with 361.
Grab the next digit (3) from the dividend, add it to 361, then carry on: 3613 / 784

Going ahead to step 7:
3613 divided by 784 is 4 with a remainder of 477.
Write down 4 as next digit of the result. 
Result so far: 1614.0
Deduct 3136 from 3613 and we're left with 477.
Append the next digit (8) from the dividend to 477 and continue with: 4778 / 784

Going ahead to step 8:
If we divide 4778 by 784, we get 6 and a remainder of 74.
The next digit of our result is 6. 
Result so far: 16146.0
Subtracting 4704 from 4778 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 9:
When dividing 740 by 784, we get 0 with a remainder of 740.
Record the quotient 0 as the next digit in the result. 
Result so far: 16146.0
The remainder is 740 after subtracting 0 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Going ahead to step 10:
784 goes into 7400 9 times with a remainder of 344.
The next digit of our result is 9. 
Result so far: 16146.09
Subtract 7056 from 7400 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 11:
784 can be fit into 3440 4 times, resulting in a remainder of 304.
The number 4 becomes the next digit in our result. 
Result so far: 16146.094
Subtracting 3136 from 3440 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 12:
The number 784 fits into 3040 3 times, leaving a remainder of 688.
Record the quotient 3 as the next digit in the result. 
Result so far: 16146.0943
If we take 2352 away from 3040, we end up with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Let's proceed to step 13:
When dividing 6880 by 784, we get 8 with a remainder of 608.
The next digit of our result is 8. 
Result so far: 16146.09438
Subtracting 6272 from 6880 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 14:
784 goes into 6080 7 times with a remainder of 592.
The number 7 becomes the next digit in our result. 
Result so far: 16146.094387
Deduct 5488 from 6080 and we're left with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Going ahead to step 15:
The number 784 fits into 5920 7 times, leaving a remainder of 432.
The next digit of our result is 7. 
Result so far: 16146.0943877
If we subtract 5488 from 5920, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

After the division, we end up with 16146.0943877 and a remainder of 4.32e-06.
