51543680 ÷ 521 
We want to divide 51543680 by 521.

On to step 1:
When dividing 5 by 521, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 521

Let's proceed to step 2:
The number 521 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 521

Moving on to step 3:
The number 521 fits into 515 0 times, leaving a remainder of 515.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 515 leaves us with 515.
Take the next digit (4) from the dividend and append it to 515, then repeat: 5154 / 521

Moving on to step 4:
521 goes into 5154 9 times with a remainder of 465.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 4689 from 5154 and we're left with 465.
Include the next digit (3) from the dividend after 465, then repeat: 4653 / 521

Going ahead to step 5:
If we divide 4653 by 521, we get 8 and a remainder of 485.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
The remainder is 485 after subtracting 4168 from 4653.
Bring next digit (6) of the dividend behind the 485 and repeat the process: 4856 / 521

Let's proceed to step 6:
521 goes into 4856 9 times with a remainder of 167.
The next digit of our result is 9. 
Result so far: 989.0
If we subtract 4689 from 4856, we get 167.
Take the next digit (8) from the dividend and append it to 167, then repeat: 1678 / 521

Let's proceed to step 7:
1678 divided by 521 is 3 with a remainder of 115.
Write down 3 as next digit of the result. 
Result so far: 9893.0
Subtract 1563 from 1678 to get 115.
Append the next digit (0) from the dividend to 115 and continue with: 1150 / 521

Moving on to step 8:
If we divide 1150 by 521, we get 2 and a remainder of 108.
The next digit of our result is 2. 
Result so far: 98932.0
Subtract 1042 from 1150 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 9:
When dividing 1080 by 521, we get 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 98932.2
If we subtract 1042 from 1080, we 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 10:
The number 521 fits into 380 0 times, leaving a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 98932.2
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
3800 divided by 521 is 7 with a remainder of 153.
Write down 7 as next digit of the result. 
Result so far: 98932.207
Subtracting 3647 from 3800 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 12:
521 goes into 1530 2 times with a remainder of 488.
Write down 2 as next digit of the result. 
Result so far: 98932.2072
The remainder is 488 after subtracting 1042 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 13:
If we divide 4880 by 521, we get 9 and a remainder of 191.
Put 9 as the next digit of the answer. 
Result so far: 98932.20729
If we subtract 4689 from 4880, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 14:
521 goes into 1910 3 times with a remainder of 347.
Put 3 as the next digit of the answer. 
Result so far: 98932.207293
Subtract 1563 from 1910 to get 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Let's proceed to step 15:
If we divide 3470 by 521, we get 6 and a remainder of 344.
Put 6 as the next digit of the answer. 
Result so far: 98932.2072936
If we subtract 3126 from 3470, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 16:
521 goes into 3440 6 times with a remainder of 314.
The next digit of our result is 6. 
Result so far: 98932.20729366
The remainder is 314 after subtracting 3126 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Our division results in 98932.20729366 with a remaining 3.14e-07.
