99925393 divided by 663 
We're looking to find how many times 663 goes into 99925393.

Going ahead to step 1:
663 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 663

Moving on to step 2:
If we divide 99 by 663, we get 0 and a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Take the next digit (9) from the dividend and append it to 99, then repeat: 999 / 663

On to step 3:
When dividing 999 by 663, we get 1 with a remainder of 336.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 663 from 999 and we're left with 336.
Include the next digit (2) from the dividend after 336, then repeat: 3362 / 663

On to step 4:
3362 divided by 663 is 5 with a remainder of 47.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 3315 away from 3362, we end up with 47.
Include the next digit (5) from the dividend after 47, then repeat: 475 / 663

On to step 5:
The number 663 fits into 475 0 times, leaving a remainder of 475.
Write down 0 as next digit of the result. 
Result so far: 150.0
Subtract 0 from 475 to get 475.
Grab the next digit (3) from the dividend, add it to 475, then carry on: 4753 / 663

On to step 6:
When dividing 4753 by 663, we get 7 with a remainder of 112.
The next digit of our result is 7. 
Result so far: 1507.0
Subtract 4641 from 4753 to get 112.
Include the next digit (9) from the dividend after 112, then repeat: 1129 / 663

Going ahead to step 7:
663 can be fit into 1129 1 times, resulting in a remainder of 466.
The next digit of our result is 1. 
Result so far: 15071.0
If we take 663 away from 1129, we end up with 466.
Grab the next digit (3) from the dividend, add it to 466, then carry on: 4663 / 663

Step 8:
663 goes into 4663 7 times with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 150717.0
The remainder is 22 after subtracting 4641 from 4663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
If we divide 220 by 663, we get 0 and a remainder of 220.
The next digit of our result is 0. 
Result so far: 150717.0
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
663 goes into 2200 3 times with a remainder of 211.
Put 3 as the next digit of the answer. 
Result so far: 150717.03
Deduct 1989 from 2200 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 11:
The number 663 fits into 2110 3 times, leaving a remainder of 121.
Use 3 as the next digit of our solution. 
Result so far: 150717.033
If we take 1989 away from 2110, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Our division results in 150717.033 with a remaining 0.0121.
