542666 ÷ 51 
Our goal is to divide 542666 by 51.

Going ahead to step 1:
If we divide 5 by 51, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 51

Step 2:
If we divide 54 by 51, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 51 from 54 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 51

Step 3:
If we divide 32 by 51, we get 0 and a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 32 leaves us with 32.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 51

Going ahead to step 4:
326 divided by 51 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Subtracting 306 from 326 leaves us with 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 51

Going ahead to step 5:
51 goes into 206 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 1064.0
Subtract 204 from 206 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 51

Going ahead to step 6:
When dividing 26 by 51, we get 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 10640.0
Subtracting 0 from 26 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
51 goes into 260 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 10640.5
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
When dividing 50 by 51, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 10640.5
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
The number 51 fits into 500 9 times, leaving a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 10640.509
The remainder is 41 after subtracting 459 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 10:
410 divided by 51 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 10640.5098
Subtracting 408 from 410 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
20 divided by 51 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10640.5098
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
When dividing 200 by 51, we get 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 10640.509803
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 13:
The number 51 fits into 470 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 10640.5098039
Deduct 459 from 470 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 14:
110 divided by 51 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 10640.50980392
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 10640.50980392 with a remainder of 8e-09.
