We look at the division of 15287991 by 289 
Our goal is to divide 15287991 by 289.

Let's proceed to step 1:
The number 289 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 289

Step 2:
15 divided by 289 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 289

Let's proceed to step 3:
289 goes into 152 0 times with a remainder of 152.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 152 after subtracting 0 from 152.
Append the next digit (8) from the dividend to 152 and continue with: 1528 / 289

On to step 4:
When dividing 1528 by 289, we get 5 with a remainder of 83.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 1445 away from 1528, we end up with 83.
Grab the next digit (7) from the dividend, add it to 83, then carry on: 837 / 289

Advancing to step 5:
289 can be fit into 837 2 times, resulting in a remainder of 259.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we subtract 578 from 837, we get 259.
Grab the next digit (9) from the dividend, add it to 259, then carry on: 2599 / 289

On to step 6:
The number 289 fits into 2599 8 times, leaving a remainder of 287.
The next digit of our result is 8. 
Result so far: 528.0
Deduct 2312 from 2599 and we're left with 287.
Take the next digit (9) from the dividend and append it to 287, then repeat: 2879 / 289

On to step 7:
2879 divided by 289 is 9 with a remainder of 278.
Record the quotient 9 as the next digit in the result. 
Result so far: 5289.0
Deduct 2601 from 2879 and we're left with 278.
Include the next digit (1) from the dividend after 278, then repeat: 2781 / 289

Let's proceed to step 8:
If we divide 2781 by 289, we get 9 and a remainder of 180.
The number 9 becomes the next digit in our result. 
Result so far: 52899.0
If we take 2601 away from 2781, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 9:
If we divide 1800 by 289, we get 6 and a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 52899.6
Deduct 1734 from 1800 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
When dividing 660 by 289, we get 2 with a remainder of 82.
Write down 2 as next digit of the result. 
Result so far: 52899.62
If we subtract 578 from 660, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 11:
289 can be fit into 820 2 times, resulting in a remainder of 242.
Put 2 as the next digit of the answer. 
Result so far: 52899.622
Deduct 578 from 820 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Our division results in 52899.622 with a remaining 0.0242.
