We divide 78122381 by 916
Our goal is to divide 78122381 by 916.

Step 1:
7 divided by 916 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 916

Moving on to step 2:
When dividing 78 by 916, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 916

Step 3:
When dividing 781 by 916, we get 0 with a remainder of 781.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 781, we get 781.
Include the next digit (2) from the dividend after 781, then repeat: 7812 / 916

Advancing to step 4:
916 goes into 7812 8 times with a remainder of 484.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 7328 from 7812, we get 484.
Append the next digit (2) from the dividend to 484 and continue with: 4842 / 916

Moving on to step 5:
If we divide 4842 by 916, we get 5 and a remainder of 262.
The next digit of our result is 5. 
Result so far: 85.0
The remainder is 262 after subtracting 4580 from 4842.
Fetch the next digit (3) from the dividend, attach it to 262 and continue: 2623 / 916

On to step 6:
When dividing 2623 by 916, we get 2 with a remainder of 791.
Record the quotient 2 as the next digit in the result. 
Result so far: 852.0
Deduct 1832 from 2623 and we're left with 791.
Include the next digit (8) from the dividend after 791, then repeat: 7918 / 916

Let's proceed to step 7:
The number 916 fits into 7918 8 times, leaving a remainder of 590.
The next digit of our result is 8. 
Result so far: 8528.0
Subtracting 7328 from 7918 leaves us with 590.
Fetch the next digit (1) from the dividend, attach it to 590 and continue: 5901 / 916

Let's proceed to step 8:
916 can be fit into 5901 6 times, resulting in a remainder of 405.
Put 6 as the next digit of the answer. 
Result so far: 85286.0
The remainder is 405 after subtracting 5496 from 5901.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 9:
If we divide 4050 by 916, we get 4 and a remainder of 386.
Put 4 as the next digit of the answer. 
Result so far: 85286.4
Subtracting 3664 from 4050 leaves us with 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 10:
The number 916 fits into 3860 4 times, leaving a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 85286.44
Deduct 3664 from 3860 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final outcome is 85286.44, with a leftover of 0.196.
