99126399 ÷ 375 
We want to divide 99126399 by 375.

Going ahead to step 1:
9 divided by 375 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 375

Going ahead to step 2:
375 goes into 99 0 times with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Grab the next digit (1) from the dividend, add it to 99, then carry on: 991 / 375

Going ahead to step 3:
375 goes into 991 2 times with a remainder of 241.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 241 after subtracting 750 from 991.
Include the next digit (2) from the dividend after 241, then repeat: 2412 / 375

Moving on to step 4:
If we divide 2412 by 375, we get 6 and a remainder of 162.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we subtract 2250 from 2412, we get 162.
Grab the next digit (6) from the dividend, add it to 162, then carry on: 1626 / 375

Let's proceed to step 5:
When dividing 1626 by 375, we get 4 with a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 264.0
If we subtract 1500 from 1626, we get 126.
Append the next digit (3) from the dividend to 126 and continue with: 1263 / 375

Moving on to step 6:
If we divide 1263 by 375, we get 3 and a remainder of 138.
Write down 3 as next digit of the result. 
Result so far: 2643.0
If we take 1125 away from 1263, we end up with 138.
Take the next digit (9) from the dividend and append it to 138, then repeat: 1389 / 375

Going ahead to step 7:
If we divide 1389 by 375, we get 3 and a remainder of 264.
The next digit of our result is 3. 
Result so far: 26433.0
Subtracting 1125 from 1389 leaves us with 264.
Grab the next digit (9) from the dividend, add it to 264, then carry on: 2649 / 375

Going ahead to step 8:
The number 375 fits into 2649 7 times, leaving a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 264337.0
If we subtract 2625 from 2649, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
The number 375 fits into 240 0 times, leaving a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 264337.0
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 10:
The number 375 fits into 2400 6 times, leaving a remainder of 150.
Use 6 as the next digit of our solution. 
Result so far: 264337.06
If we subtract 2250 from 2400, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 11:
When dividing 1500 by 375, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 264337.064
Deduct 1500 from 1500 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
375 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 264337.064
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
375 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 264337.064
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 264337.064, and the remainder is 0.0.
