We're dividing 51866432 by 204 
Let's see how many times 204 fits into 51866432.

Step 1:
204 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 204

Going ahead to step 2:
When dividing 51 by 204, we get 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 204

Step 3:
If we divide 518 by 204, we get 2 and a remainder of 110.
The next digit of our result is 2. 
Result so far: 2.0
If we take 408 away from 518, we end up with 110.
Take the next digit (6) from the dividend and append it to 110, then repeat: 1106 / 204

Going ahead to step 4:
The number 204 fits into 1106 5 times, leaving a remainder of 86.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 1020 from 1106 to get 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 204

On to step 5:
When dividing 866 by 204, we get 4 with a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 254.0
The remainder is 50 after subtracting 816 from 866.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 204

On to step 6:
204 goes into 504 2 times with a remainder of 96.
Record the quotient 2 as the next digit in the result. 
Result so far: 2542.0
If we take 408 away from 504, we end up with 96.
Fetch the next digit (3) from the dividend, attach it to 96 and continue: 963 / 204

Moving on to step 7:
When dividing 963 by 204, we get 4 with a remainder of 147.
The number 4 becomes the next digit in our result. 
Result so far: 25424.0
If we subtract 816 from 963, we get 147.
Fetch the next digit (2) from the dividend, attach it to 147 and continue: 1472 / 204

Going ahead to step 8:
1472 divided by 204 is 7 with a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 254247.0
If we take 1428 away from 1472, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
204 goes into 440 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 254247.2
Subtract 408 from 440 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
204 can be fit into 320 1 times, resulting in a remainder of 116.
The next digit of our result is 1. 
Result so far: 254247.21
Subtract 204 from 320 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 11:
204 can be fit into 1160 5 times, resulting in a remainder of 140.
The number 5 becomes the next digit in our result. 
Result so far: 254247.215
The remainder is 140 after subtracting 1020 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 12:
1400 divided by 204 is 6 with a remainder of 176.
Write down 6 as next digit of the result. 
Result so far: 254247.2156
The remainder is 176 after subtracting 1224 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 13:
204 can be fit into 1760 8 times, resulting in a remainder of 128.
Record the quotient 8 as the next digit in the result. 
Result so far: 254247.21568
If we subtract 1632 from 1760, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 14:
If we divide 1280 by 204, we get 6 and a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 254247.215686
If we take 1224 away from 1280, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 15:
When dividing 560 by 204, we get 2 with a remainder of 152.
Use 2 as the next digit of our solution. 
Result so far: 254247.2156862
If we take 408 away from 560, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 16:
The number 204 fits into 1520 7 times, leaving a remainder of 92.
Put 7 as the next digit of the answer. 
Result so far: 254247.21568627
The remainder is 92 after subtracting 1428 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final result is 254247.21568627 with a remainder of 9.2e-08.
