81185876 ÷ 986 
We want to divide 81185876 by 986.

Step 1:
When dividing 8 by 986, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 986

Advancing to step 2:
81 divided by 986 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 986

Let's proceed to step 3:
The number 986 fits into 811 0 times, leaving a remainder of 811.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 811, we end up with 811.
Include the next digit (8) from the dividend after 811, then repeat: 8118 / 986

Moving on to step 4:
8118 divided by 986 is 8 with a remainder of 230.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 7888 from 8118 leaves us with 230.
Include the next digit (5) from the dividend after 230, then repeat: 2305 / 986

On to step 5:
The number 986 fits into 2305 2 times, leaving a remainder of 333.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
The remainder is 333 after subtracting 1972 from 2305.
Take the next digit (8) from the dividend and append it to 333, then repeat: 3338 / 986

Going ahead to step 6:
986 can be fit into 3338 3 times, resulting in a remainder of 380.
The next digit of our result is 3. 
Result so far: 823.0
If we subtract 2958 from 3338, we get 380.
Append the next digit (7) from the dividend to 380 and continue with: 3807 / 986

On to step 7:
986 can be fit into 3807 3 times, resulting in a remainder of 849.
Use 3 as the next digit of our solution. 
Result so far: 8233.0
If we take 2958 away from 3807, we end up with 849.
Include the next digit (6) from the dividend after 849, then repeat: 8496 / 986

Going ahead to step 8:
The number 986 fits into 8496 8 times, leaving a remainder of 608.
The number 8 becomes the next digit in our result. 
Result so far: 82338.0
Subtracting 7888 from 8496 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed to step 9:
986 can be fit into 6080 6 times, resulting in a remainder of 164.
The number 6 becomes the next digit in our result. 
Result so far: 82338.6
Subtract 5916 from 6080 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 10:
986 goes into 1640 1 times with a remainder of 654.
The next digit of our result is 1. 
Result so far: 82338.61
Subtract 986 from 1640 to get 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Let's proceed to step 11:
If we divide 6540 by 986, we get 6 and a remainder of 624.
The next digit of our result is 6. 
Result so far: 82338.616
If we take 5916 away from 6540, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Step 12:
986 can be fit into 6240 6 times, resulting in a remainder of 324.
The number 6 becomes the next digit in our result. 
Result so far: 82338.6166
If we subtract 5916 from 6240, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The final outcome is 82338.6166, with a leftover of 0.00324.
