Let's divide 12136473 by 684
We want to divide 12136473 by 684.

Step 1:
When dividing 1 by 684, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 684

Going ahead to step 2:
When dividing 12 by 684, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 684

Advancing to step 3:
If we divide 121 by 684, we get 0 and a remainder of 121.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 121 and we're left with 121.
Take the next digit (3) from the dividend and append it to 121, then repeat: 1213 / 684

Step 4:
684 goes into 1213 1 times with a remainder of 529.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 529 after subtracting 684 from 1213.
Bring next digit (6) of the dividend behind the 529 and repeat the process: 5296 / 684

Advancing to step 5:
684 goes into 5296 7 times with a remainder of 508.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 4788 away from 5296, we end up with 508.
Take the next digit (4) from the dividend and append it to 508, then repeat: 5084 / 684

Moving on to step 6:
If we divide 5084 by 684, we get 7 and a remainder of 296.
Write down 7 as next digit of the result. 
Result so far: 177.0
If we subtract 4788 from 5084, we get 296.
Include the next digit (7) from the dividend after 296, then repeat: 2967 / 684

Let's proceed to step 7:
684 can be fit into 2967 4 times, resulting in a remainder of 231.
Record the quotient 4 as the next digit in the result. 
Result so far: 1774.0
If we subtract 2736 from 2967, we get 231.
Grab the next digit (3) from the dividend, add it to 231, then carry on: 2313 / 684

Advancing to step 8:
If we divide 2313 by 684, we get 3 and a remainder of 261.
Use 3 as the next digit of our solution. 
Result so far: 17743.0
Deduct 2052 from 2313 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Let's proceed to step 9:
When dividing 2610 by 684, we get 3 with a remainder of 558.
Write down 3 as next digit of the result. 
Result so far: 17743.3
Subtract 2052 from 2610 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Moving on to step 10:
5580 divided by 684 is 8 with a remainder of 108.
Write down 8 as next digit of the result. 
Result so far: 17743.38
If we take 5472 away from 5580, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 11:
If we divide 1080 by 684, we get 1 and a remainder of 396.
Put 1 as the next digit of the answer. 
Result so far: 17743.381
The remainder is 396 after subtracting 684 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 12:
The number 684 fits into 3960 5 times, leaving a remainder of 540.
The number 5 becomes the next digit in our result. 
Result so far: 17743.3815
If we take 3420 away from 3960, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 13:
684 goes into 5400 7 times with a remainder of 612.
Write down 7 as next digit of the result. 
Result so far: 17743.38157
If we subtract 4788 from 5400, we get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Moving on to step 14:
684 goes into 6120 8 times with a remainder of 648.
The next digit of our result is 8. 
Result so far: 17743.381578
The remainder is 648 after subtracting 5472 from 6120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Step 15:
684 goes into 6480 9 times with a remainder of 324.
The number 9 becomes the next digit in our result. 
Result so far: 17743.3815789
The remainder is 324 after subtracting 6156 from 6480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 16:
When dividing 3240 by 684, we get 4 with a remainder of 504.
Write down 4 as next digit of the result. 
Result so far: 17743.38157894
Subtract 2736 from 3240 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

The final result is 17743.38157894 with a remainder of 5.04e-07.
