72192858 ÷ 856 
Our goal is to divide 72192858 by 856.

Moving on to step 1:
If we divide 7 by 856, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 856

Let's proceed to step 2:
When dividing 72 by 856, we get 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 856

Step 3:
If we divide 721 by 856, we get 0 and a remainder of 721.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 721, we get 721.
Include the next digit (9) from the dividend after 721, then repeat: 7219 / 856

Step 4:
7219 divided by 856 is 8 with a remainder of 371.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 6848 from 7219, we get 371.
Bring next digit (2) of the dividend behind the 371 and repeat the process: 3712 / 856

Going ahead to step 5:
If we divide 3712 by 856, we get 4 and a remainder of 288.
The next digit of our result is 4. 
Result so far: 84.0
Subtract 3424 from 3712 to get 288.
Fetch the next digit (8) from the dividend, attach it to 288 and continue: 2888 / 856

Let's proceed to step 6:
856 can be fit into 2888 3 times, resulting in a remainder of 320.
Use 3 as the next digit of our solution. 
Result so far: 843.0
Deduct 2568 from 2888 and we're left with 320.
Take the next digit (5) from the dividend and append it to 320, then repeat: 3205 / 856

Advancing to step 7:
If we divide 3205 by 856, we get 3 and a remainder of 637.
The next digit of our result is 3. 
Result so far: 8433.0
Subtract 2568 from 3205 to get 637.
Append the next digit (8) from the dividend to 637 and continue with: 6378 / 856

Step 8:
856 goes into 6378 7 times with a remainder of 386.
The number 7 becomes the next digit in our result. 
Result so far: 84337.0
If we subtract 5992 from 6378, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Advancing to step 9:
856 goes into 3860 4 times with a remainder of 436.
Use 4 as the next digit of our solution. 
Result so far: 84337.4
If we subtract 3424 from 3860, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 10:
4360 divided by 856 is 5 with a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 84337.45
If we take 4280 away from 4360, 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.

Going ahead to step 11:
800 divided by 856 is 0 with a remainder of 800.
Put 0 as the next digit of the answer. 
Result so far: 84337.45
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 12:
The number 856 fits into 8000 9 times, leaving a remainder of 296.
The number 9 becomes the next digit in our result. 
Result so far: 84337.4509
The remainder is 296 after subtracting 7704 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 13:
856 can be fit into 2960 3 times, resulting in a remainder of 392.
Record the quotient 3 as the next digit in the result. 
Result so far: 84337.45093
Subtract 2568 from 2960 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 14:
If we divide 3920 by 856, we get 4 and a remainder of 496.
Record the quotient 4 as the next digit in the result. 
Result so far: 84337.450934
The remainder is 496 after subtracting 3424 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 15:
856 can be fit into 4960 5 times, resulting in a remainder of 680.
Write down 5 as next digit of the result. 
Result so far: 84337.4509345
Subtracting 4280 from 4960 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 16:
856 goes into 6800 7 times with a remainder of 808.
The number 7 becomes the next digit in our result. 
Result so far: 84337.45093457
Subtract 5992 from 6800 to get 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

The final result is 84337.45093457 with a remainder of 8.08e-07.
