861516 ÷ 91 
Let's see how many times 91 fits into 861516.

On to step 1:
If we divide 8 by 91, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 91

Let's proceed to step 2:
86 divided by 91 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 91

Step 3:
861 divided by 91 is 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 819 from 861 to get 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 91

On to step 4:
When dividing 425 by 91, we get 4 with a remainder of 61.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Subtracting 364 from 425 leaves us with 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 91

Moving on to step 5:
If we divide 611 by 91, we get 6 and a remainder of 65.
Use 6 as the next digit of our solution. 
Result so far: 946.0
If we subtract 546 from 611, we get 65.
Include the next digit (6) from the dividend after 65, then repeat: 656 / 91

Let's proceed to step 6:
656 divided by 91 is 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 9467.0
Subtracting 637 from 656 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
190 divided by 91 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 9467.2
Subtracting 182 from 190 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
When dividing 80 by 91, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 9467.2
Deduct 0 from 80 and we're left 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.

Advancing to step 9:
When dividing 800 by 91, we get 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 9467.208
Deduct 728 from 800 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
91 can be fit into 720 7 times, resulting in a remainder of 83.
Write down 7 as next digit of the result. 
Result so far: 9467.2087
Subtract 637 from 720 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 11:
When dividing 830 by 91, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 9467.20879
If we subtract 819 from 830, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
When dividing 110 by 91, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 9467.208791
If we subtract 91 from 110, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 13:
If we divide 190 by 91, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 9467.2087912
Subtracting 182 from 190 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
91 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 9467.2087912
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 9467.2087912, with a leftover of 8e-08.
