We divide 51121540 by 816
Our goal is to divide 51121540 by 816.

Advancing to step 1:
When dividing 5 by 816, we get 0 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.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 816

Step 2:
If we divide 51 by 816, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 816

Step 3:
816 goes into 511 0 times with a remainder of 511.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 511 to get 511.
Append the next digit (2) from the dividend to 511 and continue with: 5112 / 816

On to step 4:
816 goes into 5112 6 times with a remainder of 216.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 4896 from 5112 to get 216.
Append the next digit (1) from the dividend to 216 and continue with: 2161 / 816

Step 5:
816 goes into 2161 2 times with a remainder of 529.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Subtracting 1632 from 2161 leaves us with 529.
Append the next digit (5) from the dividend to 529 and continue with: 5295 / 816

Moving on to step 6:
816 can be fit into 5295 6 times, resulting in a remainder of 399.
The number 6 becomes the next digit in our result. 
Result so far: 626.0
If we subtract 4896 from 5295, we get 399.
Take the next digit (4) from the dividend and append it to 399, then repeat: 3994 / 816

Advancing to step 7:
The number 816 fits into 3994 4 times, leaving a remainder of 730.
The next digit of our result is 4. 
Result so far: 6264.0
If we take 3264 away from 3994, we end up with 730.
Fetch the next digit (0) from the dividend, attach it to 730 and continue: 7300 / 816

Let's proceed to step 8:
816 goes into 7300 8 times with a remainder of 772.
The number 8 becomes the next digit in our result. 
Result so far: 62648.0
Subtracting 6528 from 7300 leaves us with 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Let's proceed to step 9:
The number 816 fits into 7720 9 times, leaving a remainder of 376.
Record the quotient 9 as the next digit in the result. 
Result so far: 62648.9
If we take 7344 away from 7720, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 10:
When dividing 3760 by 816, we get 4 with a remainder of 496.
Record the quotient 4 as the next digit in the result. 
Result so far: 62648.94
Subtract 3264 from 3760 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 11:
816 can be fit into 4960 6 times, resulting in a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 62648.946
The remainder is 64 after subtracting 4896 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
The number 816 fits into 640 0 times, leaving a remainder of 640.
The next digit of our result is 0. 
Result so far: 62648.946
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 13:
If we divide 6400 by 816, we get 7 and a remainder of 688.
The next digit of our result is 7. 
Result so far: 62648.94607
Subtracting 5712 from 6400 leaves us with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Advancing to step 14:
When dividing 6880 by 816, we get 8 with a remainder of 352.
Record the quotient 8 as the next digit in the result. 
Result so far: 62648.946078
The remainder is 352 after subtracting 6528 from 6880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 15:
The number 816 fits into 3520 4 times, leaving a remainder of 256.
The number 4 becomes the next digit in our result. 
Result so far: 62648.9460784
Subtract 3264 from 3520 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 16:
2560 divided by 816 is 3 with a remainder of 112.
The number 3 becomes the next digit in our result. 
Result so far: 62648.94607843
The remainder is 112 after subtracting 2448 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The quotient of the division is 62648.94607843, and the remainder is 1.12e-07.
