The number 916 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 916

Step 2:
70 divided by 916 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Take the next digit (8) from the dividend and append it to 70, then repeat: 708 / 916

Going ahead to step 3:
916 goes into 708 0 times with a remainder of 708.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 708 leaves us with 708.
Bring next digit (3) of the dividend behind the 708 and repeat the process: 7083 / 916

Step 4:
916 can be fit into 7083 7 times, resulting in a remainder of 671.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 671 after subtracting 6412 from 7083.
Fetch the next digit (9) from the dividend, attach it to 671 and continue: 6719 / 916

Advancing to step 5:
If we divide 6719 by 916, we get 7 and a remainder of 307.
Put 7 as the next digit of the answer. 
Result so far: 77.0
If we subtract 6412 from 6719, we get 307.
Take the next digit (2) from the dividend and append it to 307, then repeat: 3072 / 916

Moving on to step 6:
916 goes into 3072 3 times with a remainder of 324.
The next digit of our result is 3. 
Result so far: 773.0
If we subtract 2748 from 3072, we get 324.
Include the next digit (2) from the dividend after 324, then repeat: 3242 / 916

On to step 7:
When dividing 3242 by 916, we get 3 with a remainder of 494.
Put 3 as the next digit of the answer. 
Result so far: 7733.0
The remainder is 494 after subtracting 2748 from 3242.
Append the next digit (1) from the dividend to 494 and continue with: 4941 / 916

On to step 8:
4941 divided by 916 is 5 with a remainder of 361.
Record the quotient 5 as the next digit in the result. 
Result so far: 77335.0
The remainder is 361 after subtracting 4580 from 4941.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Step 9:
The number 916 fits into 3610 3 times, leaving a remainder of 862.
Use 3 as the next digit of our solution. 
Result so far: 77335.3
Subtract 2748 from 3610 to get 862.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

Step 10:
8620 divided by 916 is 9 with a remainder of 376.
Put 9 as the next digit of the answer. 
Result so far: 77335.39
Subtract 8244 from 8620 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 11:
The number 916 fits into 3760 4 times, leaving a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 77335.394
Deduct 3664 from 3760 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 12:
916 goes into 960 1 times with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 77335.3941
The remainder is 44 after subtracting 916 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
The number 916 fits into 440 0 times, leaving a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 77335.3941
The remainder is 440 after subtracting 0 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 14:
The number 916 fits into 4400 4 times, leaving a remainder of 736.
Record the quotient 4 as the next digit in the result. 
Result so far: 77335.394104
If we take 3664 away from 4400, we end up with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Let's proceed to step 15:
The number 916 fits into 7360 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 77335.3941048
If we subtract 7328 from 7360, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 16:
When dividing 320 by 916, we get 0 with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 77335.3941048
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

In conclusion, the division gives 77335.3941048 with a balance of 3.2e-07.
