We look at the division of 15280786 by 849 
Let's see how many times 849 fits into 15280786.

Going ahead to step 1:
849 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 849

Moving on to step 2:
The number 849 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 849

Advancing to step 3:
152 divided by 849 is 0 with a remainder of 152.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 152 and we're left with 152.
Include the next digit (8) from the dividend after 152, then repeat: 1528 / 849

Going ahead to step 4:
1528 divided by 849 is 1 with a remainder of 679.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 849 from 1528, we get 679.
Fetch the next digit (0) from the dividend, attach it to 679 and continue: 6790 / 849

Let's proceed to step 5:
849 can be fit into 6790 7 times, resulting in a remainder of 847.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 5943 from 6790 and we're left with 847.
Include the next digit (7) from the dividend after 847, then repeat: 8477 / 849

On to step 6:
849 goes into 8477 9 times with a remainder of 836.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
Subtracting 7641 from 8477 leaves us with 836.
Bring next digit (8) of the dividend behind the 836 and repeat the process: 8368 / 849

Advancing to step 7:
849 can be fit into 8368 9 times, resulting in a remainder of 727.
The number 9 becomes the next digit in our result. 
Result so far: 1799.0
The remainder is 727 after subtracting 7641 from 8368.
Grab the next digit (6) from the dividend, add it to 727, then carry on: 7276 / 849

On to step 8:
When dividing 7276 by 849, we get 8 with a remainder of 484.
Record the quotient 8 as the next digit in the result. 
Result so far: 17998.0
If we subtract 6792 from 7276, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 9:
4840 divided by 849 is 5 with a remainder of 595.
The number 5 becomes the next digit in our result. 
Result so far: 17998.5
If we take 4245 away from 4840, we end up with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Advancing to step 10:
849 can be fit into 5950 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 17998.57
The remainder is 7 after subtracting 5943 from 5950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
If we divide 70 by 849, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 17998.57
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
849 goes into 700 0 times with a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 17998.57
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Our division results in 17998.57 with a remaining 0.007.
