We're dividing 22159720 by 816 
Let's see how many times 816 fits into 22159720.

Advancing to step 1:
816 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 816

Moving on to step 2:
When dividing 22 by 816, we get 0 with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 816

Step 3:
The number 816 fits into 221 0 times, leaving a remainder of 221.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 221 to get 221.
Fetch the next digit (5) from the dividend, attach it to 221 and continue: 2215 / 816

Advancing to step 4:
2215 divided by 816 is 2 with a remainder of 583.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1632 from 2215 to get 583.
Grab the next digit (9) from the dividend, add it to 583, then carry on: 5839 / 816

Moving on to step 5:
If we divide 5839 by 816, we get 7 and a remainder of 127.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 5712 from 5839 and we're left with 127.
Grab the next digit (7) from the dividend, add it to 127, then carry on: 1277 / 816

Moving on to step 6:
816 can be fit into 1277 1 times, resulting in a remainder of 461.
The next digit of our result is 1. 
Result so far: 271.0
The remainder is 461 after subtracting 816 from 1277.
Take the next digit (2) from the dividend and append it to 461, then repeat: 4612 / 816

Going ahead to step 7:
When dividing 4612 by 816, we get 5 with a remainder of 532.
Write down 5 as next digit of the result. 
Result so far: 2715.0
Deduct 4080 from 4612 and we're left with 532.
Bring next digit (0) of the dividend behind the 532 and repeat the process: 5320 / 816

Advancing to step 8:
5320 divided by 816 is 6 with a remainder of 424.
The next digit of our result is 6. 
Result so far: 27156.0
Subtracting 4896 from 5320 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 9:
The number 816 fits into 4240 5 times, leaving a remainder of 160.
The next digit of our result is 5. 
Result so far: 27156.5
Deduct 4080 from 4240 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
816 can be fit into 1600 1 times, resulting in a remainder of 784.
Use 1 as the next digit of our solution. 
Result so far: 27156.51
Subtract 816 from 1600 to get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

On to step 11:
7840 divided by 816 is 9 with a remainder of 496.
The next digit of our result is 9. 
Result so far: 27156.519
If we subtract 7344 from 7840, we 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.

Moving on to step 12:
If we divide 4960 by 816, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 27156.5196
If we take 4896 away from 4960, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
816 can be fit into 640 0 times, resulting in a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 27156.5196
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.

Advancing to step 14:
816 goes into 6400 7 times with a remainder of 688.
The number 7 becomes the next digit in our result. 
Result so far: 27156.519607
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.

Advancing to step 15:
If we divide 6880 by 816, we get 8 and a remainder of 352.
Record the quotient 8 as the next digit in the result. 
Result so far: 27156.5196078
Deduct 6528 from 6880 and we're left 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.

Going ahead to step 16:
If we divide 3520 by 816, we get 4 and a remainder of 256.
The number 4 becomes the next digit in our result. 
Result so far: 27156.51960784
Deduct 3264 from 3520 and we're left 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.

The final outcome is 27156.51960784, with a leftover of 2.56e-07.
