We look at the division of 86902492 by 549 
We want to divide 86902492 by 549.

Going ahead to step 1:
549 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 549

Advancing to step 2:
If we divide 86 by 549, we get 0 and a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 549

Moving on to step 3:
When dividing 869 by 549, we get 1 with a remainder of 320.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 549 from 869 and we're left with 320.
Take the next digit (0) from the dividend and append it to 320, then repeat: 3200 / 549

Step 4:
If we divide 3200 by 549, we get 5 and a remainder of 455.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 2745 from 3200 and we're left with 455.
Take the next digit (2) from the dividend and append it to 455, then repeat: 4552 / 549

On to step 5:
When dividing 4552 by 549, we get 8 with a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
If we subtract 4392 from 4552, we get 160.
Bring next digit (4) of the dividend behind the 160 and repeat the process: 1604 / 549

Step 6:
If we divide 1604 by 549, we get 2 and a remainder of 506.
The number 2 becomes the next digit in our result. 
Result so far: 1582.0
If we take 1098 away from 1604, we end up with 506.
Append the next digit (9) from the dividend to 506 and continue with: 5069 / 549

Step 7:
If we divide 5069 by 549, we get 9 and a remainder of 128.
Record the quotient 9 as the next digit in the result. 
Result so far: 15829.0
Subtracting 4941 from 5069 leaves us with 128.
Take the next digit (2) from the dividend and append it to 128, then repeat: 1282 / 549

Going ahead to step 8:
1282 divided by 549 is 2 with a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 158292.0
Deduct 1098 from 1282 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 9:
1840 divided by 549 is 3 with a remainder of 193.
The number 3 becomes the next digit in our result. 
Result so far: 158292.3
Subtract 1647 from 1840 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 10:
The number 549 fits into 1930 3 times, leaving a remainder of 283.
The next digit of our result is 3. 
Result so far: 158292.33
If we subtract 1647 from 1930, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

After the division, we end up with 158292.33 and a remainder of 0.283.
