We divide 10863861 by 993
We want to divide 10863861 by 993.

On to step 1:
When dividing 1 by 993, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 993

Advancing to step 2:
If we divide 10 by 993, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 993

On to step 3:
If we divide 108 by 993, we get 0 and a remainder of 108.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 108 to get 108.
Grab the next digit (6) from the dividend, add it to 108, then carry on: 1086 / 993

Step 4:
If we divide 1086 by 993, we get 1 and a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 993 from 1086 to get 93.
Append the next digit (3) from the dividend to 93 and continue with: 933 / 993

On to step 5:
If we divide 933 by 993, we get 0 and a remainder of 933.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 933 leaves us with 933.
Take the next digit (8) from the dividend and append it to 933, then repeat: 9338 / 993

Moving on to step 6:
If we divide 9338 by 993, we get 9 and a remainder of 401.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we take 8937 away from 9338, we end up with 401.
Take the next digit (6) from the dividend and append it to 401, then repeat: 4016 / 993

Moving on to step 7:
If we divide 4016 by 993, we get 4 and a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 1094.0
Subtract 3972 from 4016 to get 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 993

On to step 8:
441 divided by 993 is 0 with a remainder of 441.
The number 0 becomes the next digit in our result. 
Result so far: 10940.0
Deduct 0 from 441 and we're left with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Let's proceed to step 9:
993 goes into 4410 4 times with a remainder of 438.
Write down 4 as next digit of the result. 
Result so far: 10940.4
The remainder is 438 after subtracting 3972 from 4410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 10:
If we divide 4380 by 993, we get 4 and a remainder of 408.
Put 4 as the next digit of the answer. 
Result so far: 10940.44
If we take 3972 away from 4380, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The final outcome is 10940.44, with a leftover of 0.408.
