9864331 ÷ 986 
We want to divide 9864331 by 986.

Advancing to step 1:
If we divide 9 by 986, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 986

Let's proceed to step 2:
When dividing 98 by 986, we get 0 with a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Include the next digit (6) from the dividend after 98, then repeat: 986 / 986

Advancing to step 3:
The number 986 fits into 986 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 986 from 986, we get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 986

Step 4:
If we divide 4 by 986, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 986

Let's proceed to step 5:
986 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtract 0 from 43 to get 43.
Include the next digit (3) from the dividend after 43, then repeat: 433 / 986

Moving on to step 6:
When dividing 433 by 986, we get 0 with a remainder of 433.
Record the quotient 0 as the next digit in the result. 
Result so far: 1000.0
If we subtract 0 from 433, we get 433.
Take the next digit (1) from the dividend and append it to 433, then repeat: 4331 / 986

Step 7:
If we divide 4331 by 986, we get 4 and a remainder of 387.
Put 4 as the next digit of the answer. 
Result so far: 10004.0
The remainder is 387 after subtracting 3944 from 4331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

On to step 8:
The number 986 fits into 3870 3 times, leaving a remainder of 912.
Write down 3 as next digit of the result. 
Result so far: 10004.3
Subtracting 2958 from 3870 leaves us with 912.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9120, and continue the process.

Advancing to step 9:
986 can be fit into 9120 9 times, resulting in a remainder of 246.
The number 9 becomes the next digit in our result. 
Result so far: 10004.39
The remainder is 246 after subtracting 8874 from 9120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 10:
When dividing 2460 by 986, we get 2 with a remainder of 488.
The number 2 becomes the next digit in our result. 
Result so far: 10004.392
Subtracting 1972 from 2460 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Moving on to step 11:
The number 986 fits into 4880 4 times, leaving a remainder of 936.
Record the quotient 4 as the next digit in the result. 
Result so far: 10004.3924
Deduct 3944 from 4880 and we're left with 936.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9360, and continue the process.

Step 12:
When dividing 9360 by 986, we get 9 with a remainder of 486.
The number 9 becomes the next digit in our result. 
Result so far: 10004.39249
Subtracting 8874 from 9360 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Let's proceed to step 13:
4860 divided by 986 is 4 with a remainder of 916.
Record the quotient 4 as the next digit in the result. 
Result so far: 10004.392494
Subtracting 3944 from 4860 leaves us with 916.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9160, and continue the process.

On to step 14:
If we divide 9160 by 986, we get 9 and a remainder of 286.
Record the quotient 9 as the next digit in the result. 
Result so far: 10004.3924949
The remainder is 286 after subtracting 8874 from 9160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 15:
986 can be fit into 2860 2 times, resulting in a remainder of 888.
Record the quotient 2 as the next digit in the result. 
Result so far: 10004.39249492
Subtracting 1972 from 2860 leaves us with 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

The final result is 10004.39249492 with a remainder of 8.88e-07.
