11531588 ÷ 789 
Let's see how many times 789 fits into 11531588.

On to step 1:
1 divided by 789 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 789

On to step 2:
11 divided by 789 is 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 789

Moving on to step 3:
115 divided by 789 is 0 with a remainder of 115.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 115 and we're left with 115.
Include the next digit (3) from the dividend after 115, then repeat: 1153 / 789

Let's proceed to step 4:
The number 789 fits into 1153 1 times, leaving a remainder of 364.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 789 from 1153 to get 364.
Bring next digit (1) of the dividend behind the 364 and repeat the process: 3641 / 789

Going ahead to step 5:
789 can be fit into 3641 4 times, resulting in a remainder of 485.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 485 after subtracting 3156 from 3641.
Bring next digit (5) of the dividend behind the 485 and repeat the process: 4855 / 789

Going ahead to step 6:
789 goes into 4855 6 times with a remainder of 121.
Put 6 as the next digit of the answer. 
Result so far: 146.0
Subtracting 4734 from 4855 leaves us with 121.
Grab the next digit (8) from the dividend, add it to 121, then carry on: 1218 / 789

Let's proceed to step 7:
1218 divided by 789 is 1 with a remainder of 429.
Put 1 as the next digit of the answer. 
Result so far: 1461.0
The remainder is 429 after subtracting 789 from 1218.
Take the next digit (8) from the dividend and append it to 429, then repeat: 4298 / 789

Going ahead to step 8:
The number 789 fits into 4298 5 times, leaving a remainder of 353.
Write down 5 as next digit of the result. 
Result so far: 14615.0
If we subtract 3945 from 4298, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Step 9:
When dividing 3530 by 789, we get 4 with a remainder of 374.
Use 4 as the next digit of our solution. 
Result so far: 14615.4
If we subtract 3156 from 3530, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 10:
789 can be fit into 3740 4 times, resulting in a remainder of 584.
The next digit of our result is 4. 
Result so far: 14615.44
Subtracting 3156 from 3740 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

The quotient of the division is 14615.44, and the remainder is 0.584.
