We look at the division of 5386010 by 663 
We want to figure out the number of times 5386010 can be divided by 663.

Advancing to step 1:
When dividing 5 by 663, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 663

Going ahead to step 2:
663 goes into 53 0 times with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 663

Step 3:
The number 663 fits into 538 0 times, leaving a remainder of 538.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 538, we end up with 538.
Fetch the next digit (6) from the dividend, attach it to 538 and continue: 5386 / 663

Step 4:
When dividing 5386 by 663, we get 8 with a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 5304 from 5386 and we're left with 82.
Append the next digit (0) from the dividend to 82 and continue with: 820 / 663

Moving on to step 5:
The number 663 fits into 820 1 times, leaving a remainder of 157.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
The remainder is 157 after subtracting 663 from 820.
Bring next digit (1) of the dividend behind the 157 and repeat the process: 1571 / 663

Advancing to step 6:
1571 divided by 663 is 2 with a remainder of 245.
The number 2 becomes the next digit in our result. 
Result so far: 812.0
Deduct 1326 from 1571 and we're left with 245.
Include the next digit (0) from the dividend after 245, then repeat: 2450 / 663

Let's proceed to step 7:
When dividing 2450 by 663, we get 3 with a remainder of 461.
Put 3 as the next digit of the answer. 
Result so far: 8123.0
If we take 1989 away from 2450, we end up with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Let's proceed to step 8:
If we divide 4610 by 663, we get 6 and a remainder of 632.
The number 6 becomes the next digit in our result. 
Result so far: 8123.6
Deduct 3978 from 4610 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 9:
663 goes into 6320 9 times with a remainder of 353.
Put 9 as the next digit of the answer. 
Result so far: 8123.69
If we take 5967 away from 6320, we end up with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

On to step 10:
If we divide 3530 by 663, we get 5 and a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 8123.695
The remainder is 215 after subtracting 3315 from 3530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 11:
When dividing 2150 by 663, we get 3 with a remainder of 161.
Put 3 as the next digit of the answer. 
Result so far: 8123.6953
If we take 1989 away from 2150, we end up with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Let's proceed to step 12:
If we divide 1610 by 663, we get 2 and a remainder of 284.
The next digit of our result is 2. 
Result so far: 8123.69532
If we take 1326 away from 1610, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 13:
663 can be fit into 2840 4 times, resulting in a remainder of 188.
Use 4 as the next digit of our solution. 
Result so far: 8123.695324
If we take 2652 away from 2840, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 14:
When dividing 1880 by 663, we get 2 with a remainder of 554.
Record the quotient 2 as the next digit in the result. 
Result so far: 8123.6953242
If we subtract 1326 from 1880, we get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Going ahead to step 15:
If we divide 5540 by 663, we get 8 and a remainder of 236.
Put 8 as the next digit of the answer. 
Result so far: 8123.69532428
Subtract 5304 from 5540 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Our division results in 8123.69532428 with a remaining 2.36e-07.
