639011 divided by 51 
We're looking to find how many times 51 goes into 639011.

Going ahead to step 1:
When dividing 6 by 51, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 51

Let's proceed to step 2:
When dividing 63 by 51, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 51 away from 63, we end up with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 51

On to step 3:
51 goes into 129 2 times with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 102 from 129, we get 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 51

Advancing to step 4:
270 divided by 51 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtracting 255 from 270 leaves us with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 51

Going ahead to step 5:
If we divide 151 by 51, we get 2 and a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 1252.0
Subtract 102 from 151 to get 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 51

Moving on to step 6:
If we divide 491 by 51, we get 9 and a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 12529.0
The remainder is 32 after subtracting 459 from 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
51 can be fit into 320 6 times, resulting in a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 12529.6
Subtract 306 from 320 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
If we divide 140 by 51, we get 2 and a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 12529.62
If we take 102 away from 140, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
51 goes into 380 7 times with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 12529.627
The remainder is 23 after subtracting 357 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
230 divided by 51 is 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 12529.6274
If we subtract 204 from 230, we get 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 11:
The number 51 fits into 260 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12529.62745
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.

On to step 12:
The number 51 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 12529.62745
If we take 0 away from 50, we end up 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.

Going ahead to step 13:
If we divide 500 by 51, we get 9 and a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 12529.6274509
Subtract 459 from 500 to get 41.
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 14:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 12529.62745098
If we take 408 away from 410, we end up 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.

The final result is 12529.62745098 with a remainder of 2e-09.
