Append the next digit (6) from the dividend to 8 and continue with: 86 / 916

Moving on to step 2:
The number 916 fits into 86 0 times, leaving a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 916

Moving on to step 3:
916 goes into 861 0 times with a remainder of 861.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 861 leaves us with 861.
Include the next digit (7) from the dividend after 861, then repeat: 8617 / 916

Let's proceed to step 4:
When dividing 8617 by 916, we get 9 with a remainder of 373.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 8244 from 8617, we get 373.
Take the next digit (2) from the dividend and append it to 373, then repeat: 3732 / 916

Moving on to step 5:
When dividing 3732 by 916, we get 4 with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtracting 3664 from 3732 leaves us with 68.
Include the next digit (3) from the dividend after 68, then repeat: 683 / 916

Let's proceed to step 6:
The number 916 fits into 683 0 times, leaving a remainder of 683.
The number 0 becomes the next digit in our result. 
Result so far: 940.0
Subtract 0 from 683 to get 683.
Include the next digit (7) from the dividend after 683, then repeat: 6837 / 916

Going ahead to step 7:
916 can be fit into 6837 7 times, resulting in a remainder of 425.
The next digit of our result is 7. 
Result so far: 9407.0
The remainder is 425 after subtracting 6412 from 6837.
Fetch the next digit (0) from the dividend, attach it to 425 and continue: 4250 / 916

Moving on to step 8:
If we divide 4250 by 916, we get 4 and a remainder of 586.
The next digit of our result is 4. 
Result so far: 94074.0
Subtracting 3664 from 4250 leaves us with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Moving on to step 9:
The number 916 fits into 5860 6 times, leaving a remainder of 364.
The number 6 becomes the next digit in our result. 
Result so far: 94074.6
If we subtract 5496 from 5860, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 10:
916 goes into 3640 3 times with a remainder of 892.
Put 3 as the next digit of the answer. 
Result so far: 94074.63
Deduct 2748 from 3640 and we're left with 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

Let's proceed to step 11:
916 goes into 8920 9 times with a remainder of 676.
Put 9 as the next digit of the answer. 
Result so far: 94074.639
Subtract 8244 from 8920 to get 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

On to step 12:
If we divide 6760 by 916, we get 7 and a remainder of 348.
Put 7 as the next digit of the answer. 
Result so far: 94074.6397
The remainder is 348 after subtracting 6412 from 6760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 13:
When dividing 3480 by 916, we get 3 with a remainder of 732.
The number 3 becomes the next digit in our result. 
Result so far: 94074.63973
Deduct 2748 from 3480 and we're left with 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Advancing to step 14:
When dividing 7320 by 916, we get 7 with a remainder of 908.
Put 7 as the next digit of the answer. 
Result so far: 94074.639737
The remainder is 908 after subtracting 6412 from 7320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9080, and continue the process.

Step 15:
When dividing 9080 by 916, we get 9 with a remainder of 836.
Put 9 as the next digit of the answer. 
Result so far: 94074.6397379
Subtract 8244 from 9080 to get 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Going ahead to step 16:
If we divide 8360 by 916, we get 9 and a remainder of 116.
The number 9 becomes the next digit in our result. 
Result so far: 94074.63973799
If we subtract 8244 from 8360, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Our division results in 94074.63973799 with a remaining 1.16e-07.
