12783420 divided by 204 
We want to divide 12783420 by 204.

On to step 1:
1 divided by 204 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 204

Step 2:
If we divide 12 by 204, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 204

Moving on to step 3:
The number 204 fits into 127 0 times, leaving a remainder of 127.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 127, we end up with 127.
Grab the next digit (8) from the dividend, add it to 127, then carry on: 1278 / 204

Advancing to step 4:
When dividing 1278 by 204, we get 6 with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 54 after subtracting 1224 from 1278.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 204

Advancing to step 5:
When dividing 543 by 204, we get 2 with a remainder of 135.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
Deduct 408 from 543 and we're left with 135.
Bring next digit (4) of the dividend behind the 135 and repeat the process: 1354 / 204

Advancing to step 6:
When dividing 1354 by 204, we get 6 with a remainder of 130.
Put 6 as the next digit of the answer. 
Result so far: 626.0
Subtracting 1224 from 1354 leaves us with 130.
Take the next digit (2) from the dividend and append it to 130, then repeat: 1302 / 204

Advancing to step 7:
The number 204 fits into 1302 6 times, leaving a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 6266.0
Deduct 1224 from 1302 and we're left with 78.
Fetch the next digit (0) from the dividend, attach it to 78 and continue: 780 / 204

Advancing to step 8:
204 can be fit into 780 3 times, resulting in a remainder of 168.
Use 3 as the next digit of our solution. 
Result so far: 62663.0
The remainder is 168 after subtracting 612 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 9:
If we divide 1680 by 204, we get 8 and a remainder of 48.
The next digit of our result is 8. 
Result so far: 62663.8
Subtract 1632 from 1680 to 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 10:
When dividing 480 by 204, we get 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 62663.82
The remainder is 72 after subtracting 408 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
If we divide 720 by 204, we get 3 and a remainder of 108.
Write down 3 as next digit of the result. 
Result so far: 62663.823
Subtract 612 from 720 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 12:
The number 204 fits into 1080 5 times, leaving a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 62663.8235
If we subtract 1020 from 1080, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
When dividing 600 by 204, we get 2 with a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 62663.82352
If we take 408 away from 600, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 14:
If we divide 1920 by 204, we get 9 and a remainder of 84.
Record the quotient 9 as the next digit in the result. 
Result so far: 62663.823529
If we subtract 1836 from 1920, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 15:
204 can be fit into 840 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 62663.8235294
Subtracting 816 from 840 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 16:
The number 204 fits into 240 1 times, leaving a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 62663.82352941
Deduct 204 from 240 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 62663.82352941, with a leftover of 3.6e-08.
