42956990 divided by 816 
We want to divide 42956990 by 816.

Moving on to step 1:
816 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 816

On to step 2:
When dividing 42 by 816, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 816

Let's proceed to step 3:
When dividing 429 by 816, we get 0 with a remainder of 429.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 429, we end up with 429.
Append the next digit (5) from the dividend to 429 and continue with: 4295 / 816

Going ahead to step 4:
4295 divided by 816 is 5 with a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 4080 from 4295 to get 215.
Take the next digit (6) from the dividend and append it to 215, then repeat: 2156 / 816

On to step 5:
2156 divided by 816 is 2 with a remainder of 524.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we take 1632 away from 2156, we end up with 524.
Take the next digit (9) from the dividend and append it to 524, then repeat: 5249 / 816

Step 6:
If we divide 5249 by 816, we get 6 and a remainder of 353.
Write down 6 as next digit of the result. 
Result so far: 526.0
If we take 4896 away from 5249, we end up with 353.
Grab the next digit (9) from the dividend, add it to 353, then carry on: 3539 / 816

Let's proceed to step 7:
816 can be fit into 3539 4 times, resulting in a remainder of 275.
Write down 4 as next digit of the result. 
Result so far: 5264.0
Subtract 3264 from 3539 to get 275.
Grab the next digit (0) from the dividend, add it to 275, then carry on: 2750 / 816

Going ahead to step 8:
If we divide 2750 by 816, we get 3 and a remainder of 302.
Record the quotient 3 as the next digit in the result. 
Result so far: 52643.0
If we subtract 2448 from 2750, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 9:
816 goes into 3020 3 times with a remainder of 572.
The number 3 becomes the next digit in our result. 
Result so far: 52643.3
If we subtract 2448 from 3020, we get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Going ahead to step 10:
816 can be fit into 5720 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 52643.37
The remainder is 8 after subtracting 5712 from 5720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
If we divide 80 by 816, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 52643.37
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
The number 816 fits into 800 0 times, leaving a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 52643.37
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final result is 52643.37 with a remainder of 0.008.
