We look at the division of 549925 by 86 
Let's see how many times 86 fits into 549925.

Moving on to step 1:
86 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 86

Advancing to step 2:
54 divided by 86 is 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 86

Moving on to step 3:
86 can be fit into 549 6 times, resulting in a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 516 away from 549, we end up with 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 86

Moving on to step 4:
The number 86 fits into 339 3 times, leaving a remainder of 81.
The next digit of our result is 3. 
Result so far: 63.0
If we subtract 258 from 339, we get 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 86

On to step 5:
When dividing 812 by 86, we get 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 639.0
If we subtract 774 from 812, we get 38.
Grab the next digit (5) from the dividend, add it to 38, then carry on: 385 / 86

Advancing to step 6:
When dividing 385 by 86, we get 4 with a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 6394.0
If we take 344 away from 385, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
86 goes into 410 4 times with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 6394.4
If we subtract 344 from 410, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
86 can be fit into 660 7 times, resulting in a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 6394.47
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
When dividing 580 by 86, we get 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 6394.476
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
86 goes into 640 7 times with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 6394.4767
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 6394.47674
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
86 goes into 360 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 6394.476744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 6394.476744, with a leftover of 1.6e-06.
