521201 ÷ 51 
Let's see how many times 51 fits into 521201.

Moving on to step 1:
51 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 51

Going ahead to step 2:
If we divide 52 by 51, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 1 after subtracting 51 from 52.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 51

Step 3:
11 divided by 51 is 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 11 and we're left with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 51

Moving on to step 4:
If we divide 112 by 51, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 102.0
The remainder is 10 after subtracting 102 from 112.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 51

On to step 5:
100 divided by 51 is 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 1021.0
The remainder is 49 after subtracting 51 from 100.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 51

Step 6:
491 divided by 51 is 9 with a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 10219.0
If we take 459 away from 491, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
320 divided by 51 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 10219.6
Deduct 306 from 320 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
The number 51 fits into 140 2 times, leaving a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 10219.62
Subtract 102 from 140 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
51 can be fit into 380 7 times, resulting in a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 10219.627
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 10:
230 divided by 51 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 10219.6274
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.

Advancing to step 11:
51 goes into 260 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 10219.62745
Subtracting 255 from 260 leaves us with 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 12:
50 divided by 51 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 10219.62745
Subtract 0 from 50 to get 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 13:
The number 51 fits into 500 9 times, leaving a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 10219.6274509
If we take 459 away from 500, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 14:
51 goes into 410 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 10219.62745098
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.

In conclusion, the division gives 10219.62745098 with a balance of 2e-09.
