521081 ÷ 51 
We want to figure out the number of times 521081 can be divided by 51.

On to step 1:
The number 51 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 51

Advancing to step 2:
When dividing 52 by 51, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 51 from 52 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 51

Step 3:
51 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 11, we get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 51

Step 4:
If we divide 110 by 51, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Subtracting 102 from 110 leaves us with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 51

Advancing to step 5:
51 goes into 88 1 times with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1021.0
If we take 51 away from 88, we end up with 37.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 51

Advancing to step 6:
51 can be fit into 371 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 10217.0
Deduct 357 from 371 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.

Going ahead to step 7:
If we divide 140 by 51, we get 2 and a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 10217.2
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.

Let's proceed to step 8:
380 divided by 51 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 10217.27
Deduct 357 from 380 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
51 goes into 230 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 10217.274
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
51 can be fit into 260 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 10217.2745
The remainder is 5 after subtracting 255 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
If we divide 50 by 51, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10217.2745
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 12:
51 goes into 500 9 times with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 10217.274509
Subtracting 459 from 500 leaves us 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.

Let's proceed to step 13:
51 can be fit into 410 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 10217.2745098
Deduct 408 from 410 and we're left 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.

Step 14:
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: 10217.2745098
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 10217.2745098, with a leftover of 2e-08.
