Let's divide 90084354 by 663
Our goal is to divide 90084354 by 663.

Going ahead to step 1:
663 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 663

Moving on to step 2:
When dividing 90 by 663, we get 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Fetch the next digit (0) from the dividend, attach it to 90 and continue: 900 / 663

Going ahead to step 3:
663 can be fit into 900 1 times, resulting in a remainder of 237.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 663 from 900 leaves us with 237.
Include the next digit (8) from the dividend after 237, then repeat: 2378 / 663

Moving on to step 4:
663 can be fit into 2378 3 times, resulting in a remainder of 389.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1989 from 2378 leaves us with 389.
Bring next digit (4) of the dividend behind the 389 and repeat the process: 3894 / 663

Step 5:
663 goes into 3894 5 times with a remainder of 579.
The next digit of our result is 5. 
Result so far: 135.0
Subtracting 3315 from 3894 leaves us with 579.
Take the next digit (3) from the dividend and append it to 579, then repeat: 5793 / 663

Step 6:
5793 divided by 663 is 8 with a remainder of 489.
The next digit of our result is 8. 
Result so far: 1358.0
If we subtract 5304 from 5793, we get 489.
Fetch the next digit (5) from the dividend, attach it to 489 and continue: 4895 / 663

Advancing to step 7:
If we divide 4895 by 663, we get 7 and a remainder of 254.
Use 7 as the next digit of our solution. 
Result so far: 13587.0
If we take 4641 away from 4895, we end up with 254.
Include the next digit (4) from the dividend after 254, then repeat: 2544 / 663

Going ahead to step 8:
663 can be fit into 2544 3 times, resulting in a remainder of 555.
Put 3 as the next digit of the answer. 
Result so far: 135873.0
Deduct 1989 from 2544 and we're left with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Let's proceed to step 9:
If we divide 5550 by 663, we get 8 and a remainder of 246.
Record the quotient 8 as the next digit in the result. 
Result so far: 135873.8
The remainder is 246 after subtracting 5304 from 5550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 10:
If we divide 2460 by 663, we get 3 and a remainder of 471.
Put 3 as the next digit of the answer. 
Result so far: 135873.83
Subtract 1989 from 2460 to get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Going ahead to step 11:
If we divide 4710 by 663, we get 7 and a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 135873.837
If we subtract 4641 from 4710, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 12:
If we divide 690 by 663, we get 1 and a remainder of 27.
The next digit of our result is 1. 
Result so far: 135873.8371
Subtracting 663 from 690 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
270 divided by 663 is 0 with a remainder of 270.
Put 0 as the next digit of the answer. 
Result so far: 135873.8371
The remainder is 270 after subtracting 0 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 14:
663 goes into 2700 4 times with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 135873.837104
Subtract 2652 from 2700 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 15:
If we divide 480 by 663, we get 0 and a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 135873.837104
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 16:
663 can be fit into 4800 7 times, resulting in a remainder of 159.
Write down 7 as next digit of the result. 
Result so far: 135873.83710407
If we take 4641 away from 4800, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Our division results in 135873.83710407 with a remaining 1.59e-07.
