571820 divided by 51 
Let's see how many times 51 fits into 571820.

Step 1:
If we divide 5 by 51, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 51

Going ahead to step 2:
If we divide 57 by 51, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 51 from 57, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 51

Moving on to step 3:
If we divide 61 by 51, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 51 from 61 to get 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 51

Step 4:
51 goes into 108 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
Subtract 102 from 108 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 51

Moving on to step 5:
When dividing 62 by 51, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1121.0
If we subtract 51 from 62, we get 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 51

Going ahead to step 6:
When dividing 110 by 51, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 11212.0
Subtract 102 from 110 to 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.

Advancing to step 7:
51 can be fit into 80 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 11212.1
If we take 51 away from 80, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 8:
51 goes into 290 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 11212.15
If we subtract 255 from 290, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
51 goes into 350 6 times with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 11212.156
If we take 306 away from 350, 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.

Going ahead to step 10:
The number 51 fits into 440 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 11212.1568
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.

On to step 11:
When dividing 320 by 51, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 11212.15686
If we subtract 306 from 320, we 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.

Advancing to step 12:
140 divided by 51 is 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 11212.156862
Deduct 102 from 140 and we're left 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.

Going ahead to step 13:
51 goes into 380 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 11212.1568627
Subtract 357 from 380 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 14:
When dividing 230 by 51, we get 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 11212.15686274
Subtracting 204 from 230 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.

In conclusion, the division gives 11212.15686274 with a balance of 2.6e-08.
