We look at the division of 99150012 by 263 
We want to figure out the number of times 99150012 can be divided by 263.

Let's proceed to step 1:
If we divide 9 by 263, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 263

Advancing to step 2:
If we divide 99 by 263, we get 0 and a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Take the next digit (1) from the dividend and append it to 99, then repeat: 991 / 263

Step 3:
If we divide 991 by 263, we get 3 and a remainder of 202.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 789 from 991 leaves us with 202.
Grab the next digit (5) from the dividend, add it to 202, then carry on: 2025 / 263

On to step 4:
The number 263 fits into 2025 7 times, leaving a remainder of 184.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtract 1841 from 2025 to get 184.
Bring next digit (0) of the dividend behind the 184 and repeat the process: 1840 / 263

Advancing to step 5:
If we divide 1840 by 263, we get 6 and a remainder of 262.
The number 6 becomes the next digit in our result. 
Result so far: 376.0
Deduct 1578 from 1840 and we're left with 262.
Include the next digit (0) from the dividend after 262, then repeat: 2620 / 263

Advancing to step 6:
The number 263 fits into 2620 9 times, leaving a remainder of 253.
Use 9 as the next digit of our solution. 
Result so far: 3769.0
The remainder is 253 after subtracting 2367 from 2620.
Bring next digit (1) of the dividend behind the 253 and repeat the process: 2531 / 263

Step 7:
2531 divided by 263 is 9 with a remainder of 164.
Use 9 as the next digit of our solution. 
Result so far: 37699.0
The remainder is 164 after subtracting 2367 from 2531.
Take the next digit (2) from the dividend and append it to 164, then repeat: 1642 / 263

Going ahead to step 8:
The number 263 fits into 1642 6 times, leaving a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 376996.0
The remainder is 64 after subtracting 1578 from 1642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
The number 263 fits into 640 2 times, leaving a remainder of 114.
The next digit of our result is 2. 
Result so far: 376996.2
If we subtract 526 from 640, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 10:
When dividing 1140 by 263, we get 4 with a remainder of 88.
The next digit of our result is 4. 
Result so far: 376996.24
If we subtract 1052 from 1140, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 11:
880 divided by 263 is 3 with a remainder of 91.
Record the quotient 3 as the next digit in the result. 
Result so far: 376996.243
Subtracting 789 from 880 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 12:
910 divided by 263 is 3 with a remainder of 121.
The next digit of our result is 3. 
Result so far: 376996.2433
If we take 789 away from 910, 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.

After the division, we end up with 376996.2433 and a remainder of 0.00121.
