We're dividing 51338622 by 816 
We're looking to find how many times 816 goes into 51338622.

Step 1:
When dividing 5 by 816, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 816

On to step 2:
816 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 816

On to step 3:
816 can be fit into 513 0 times, resulting in a remainder of 513.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 513 leaves us with 513.
Take the next digit (3) from the dividend and append it to 513, then repeat: 5133 / 816

Step 4:
5133 divided by 816 is 6 with a remainder of 237.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 4896 from 5133 leaves us with 237.
Append the next digit (8) from the dividend to 237 and continue with: 2378 / 816

Moving on to step 5:
When dividing 2378 by 816, we get 2 with a remainder of 746.
Write down 2 as next digit of the result. 
Result so far: 62.0
If we subtract 1632 from 2378, we get 746.
Grab the next digit (6) from the dividend, add it to 746, then carry on: 7466 / 816

Going ahead to step 6:
816 can be fit into 7466 9 times, resulting in a remainder of 122.
Record the quotient 9 as the next digit in the result. 
Result so far: 629.0
The remainder is 122 after subtracting 7344 from 7466.
Bring next digit (2) of the dividend behind the 122 and repeat the process: 1222 / 816

Let's proceed to step 7:
When dividing 1222 by 816, we get 1 with a remainder of 406.
Use 1 as the next digit of our solution. 
Result so far: 6291.0
Subtract 816 from 1222 to get 406.
Take the next digit (2) from the dividend and append it to 406, then repeat: 4062 / 816

On to step 8:
When dividing 4062 by 816, we get 4 with a remainder of 798.
The number 4 becomes the next digit in our result. 
Result so far: 62914.0
The remainder is 798 after subtracting 3264 from 4062.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Going ahead to step 9:
When dividing 7980 by 816, we get 9 with a remainder of 636.
Write down 9 as next digit of the result. 
Result so far: 62914.9
Deduct 7344 from 7980 and we're left with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Let's proceed to step 10:
The number 816 fits into 6360 7 times, leaving a remainder of 648.
The next digit of our result is 7. 
Result so far: 62914.97
Deduct 5712 from 6360 and we're left with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Going ahead to step 11:
The number 816 fits into 6480 7 times, leaving a remainder of 768.
Put 7 as the next digit of the answer. 
Result so far: 62914.977
Deduct 5712 from 6480 and we're left with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

The quotient of the division is 62914.977, and the remainder is 0.0768.
