32121904 ÷ 816 
We want to divide 32121904 by 816.

Let's proceed to step 1:
816 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 816

Advancing to step 2:
32 divided by 816 is 0 with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 816

Step 3:
The number 816 fits into 321 0 times, leaving a remainder of 321.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 321, we get 321.
Fetch the next digit (2) from the dividend, attach it to 321 and continue: 3212 / 816

Advancing to step 4:
816 goes into 3212 3 times with a remainder of 764.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 2448 from 3212, we get 764.
Append the next digit (1) from the dividend to 764 and continue with: 7641 / 816

Let's proceed to step 5:
7641 divided by 816 is 9 with a remainder of 297.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Deduct 7344 from 7641 and we're left with 297.
Bring next digit (9) of the dividend behind the 297 and repeat the process: 2979 / 816

Advancing to step 6:
816 can be fit into 2979 3 times, resulting in a remainder of 531.
The number 3 becomes the next digit in our result. 
Result so far: 393.0
The remainder is 531 after subtracting 2448 from 2979.
Grab the next digit (0) from the dividend, add it to 531, then carry on: 5310 / 816

Advancing to step 7:
If we divide 5310 by 816, we get 6 and a remainder of 414.
Record the quotient 6 as the next digit in the result. 
Result so far: 3936.0
Subtracting 4896 from 5310 leaves us with 414.
Append the next digit (4) from the dividend to 414 and continue with: 4144 / 816

Step 8:
4144 divided by 816 is 5 with a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 39365.0
The remainder is 64 after subtracting 4080 from 4144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
640 divided by 816 is 0 with a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 39365.0
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 10:
6400 divided by 816 is 7 with a remainder of 688.
The number 7 becomes the next digit in our result. 
Result so far: 39365.07
If we subtract 5712 from 6400, we get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Let's proceed to step 11:
When dividing 6880 by 816, we get 8 with a remainder of 352.
Put 8 as the next digit of the answer. 
Result so far: 39365.078
Subtracting 6528 from 6880 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 12:
816 goes into 3520 4 times with a remainder of 256.
Record the quotient 4 as the next digit in the result. 
Result so far: 39365.0784
If we take 3264 away from 3520, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 13:
The number 816 fits into 2560 3 times, leaving a remainder of 112.
Write down 3 as next digit of the result. 
Result so far: 39365.07843
Deduct 2448 from 2560 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 14:
1120 divided by 816 is 1 with a remainder of 304.
Use 1 as the next digit of our solution. 
Result so far: 39365.078431
If we subtract 816 from 1120, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 15:
816 goes into 3040 3 times with a remainder of 592.
Write down 3 as next digit of the result. 
Result so far: 39365.0784313
If we take 2448 away from 3040, we end up with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Let's proceed to step 16:
If we divide 5920 by 816, we get 7 and a remainder of 208.
The number 7 becomes the next digit in our result. 
Result so far: 39365.07843137
Subtract 5712 from 5920 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final result is 39365.07843137 with a remainder of 2.08e-07.
