30243966 ÷ 354 
Let's see how many times 354 fits into 30243966.

On to step 1:
354 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 354

Moving on to step 2:
The number 354 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 354

Step 3:
The number 354 fits into 302 0 times, leaving a remainder of 302.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 302 to get 302.
Grab the next digit (4) from the dividend, add it to 302, then carry on: 3024 / 354

Step 4:
354 goes into 3024 8 times with a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 192 after subtracting 2832 from 3024.
Fetch the next digit (3) from the dividend, attach it to 192 and continue: 1923 / 354

Advancing to step 5:
1923 divided by 354 is 5 with a remainder of 153.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we subtract 1770 from 1923, we get 153.
Fetch the next digit (9) from the dividend, attach it to 153 and continue: 1539 / 354

Let's proceed to step 6:
The number 354 fits into 1539 4 times, leaving a remainder of 123.
Write down 4 as next digit of the result. 
Result so far: 854.0
Deduct 1416 from 1539 and we're left with 123.
Take the next digit (6) from the dividend and append it to 123, then repeat: 1236 / 354

On to step 7:
When dividing 1236 by 354, we get 3 with a remainder of 174.
Record the quotient 3 as the next digit in the result. 
Result so far: 8543.0
Subtract 1062 from 1236 to get 174.
Fetch the next digit (6) from the dividend, attach it to 174 and continue: 1746 / 354

Moving on to step 8:
When dividing 1746 by 354, we get 4 with a remainder of 330.
The next digit of our result is 4. 
Result so far: 85434.0
Deduct 1416 from 1746 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 9:
When dividing 3300 by 354, we get 9 with a remainder of 114.
Record the quotient 9 as the next digit in the result. 
Result so far: 85434.9
If we take 3186 away from 3300, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 10:
354 goes into 1140 3 times with a remainder of 78.
The next digit of our result is 3. 
Result so far: 85434.93
If we take 1062 away from 1140, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 11:
The number 354 fits into 780 2 times, leaving a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 85434.932
Subtracting 708 from 780 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 12:
If we divide 720 by 354, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 85434.9322
Deduct 708 from 720 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 85434.9322, and the remainder is 0.00012.
