We divide 99783809 by 345
We want to divide 99783809 by 345.

Going ahead to step 1:
When dividing 9 by 345, we get 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.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 345

Moving on to step 2:
The number 345 fits into 99 0 times, leaving a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 345

On to step 3:
345 goes into 997 2 times with a remainder of 307.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 690 from 997 leaves us with 307.
Fetch the next digit (8) from the dividend, attach it to 307 and continue: 3078 / 345

Step 4:
3078 divided by 345 is 8 with a remainder of 318.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we subtract 2760 from 3078, we get 318.
Take the next digit (3) from the dividend and append it to 318, then repeat: 3183 / 345

Step 5:
The number 345 fits into 3183 9 times, leaving a remainder of 78.
Use 9 as the next digit of our solution. 
Result so far: 289.0
If we take 3105 away from 3183, we end up with 78.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 345

Advancing to step 6:
If we divide 788 by 345, we get 2 and a remainder of 98.
Write down 2 as next digit of the result. 
Result so far: 2892.0
Subtract 690 from 788 to get 98.
Include the next digit (0) from the dividend after 98, then repeat: 980 / 345

Going ahead to step 7:
980 divided by 345 is 2 with a remainder of 290.
The number 2 becomes the next digit in our result. 
Result so far: 28922.0
The remainder is 290 after subtracting 690 from 980.
Append the next digit (9) from the dividend to 290 and continue with: 2909 / 345

Moving on to step 8:
The number 345 fits into 2909 8 times, leaving a remainder of 149.
The next digit of our result is 8. 
Result so far: 289228.0
Subtract 2760 from 2909 to get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Let's proceed to step 9:
When dividing 1490 by 345, we get 4 with a remainder of 110.
The next digit of our result is 4. 
Result so far: 289228.4
Deduct 1380 from 1490 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
345 goes into 1100 3 times with a remainder of 65.
The next digit of our result is 3. 
Result so far: 289228.43
If we subtract 1035 from 1100, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 11:
When dividing 650 by 345, we get 1 with a remainder of 305.
Write down 1 as next digit of the result. 
Result so far: 289228.431
Deduct 345 from 650 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 12:
The number 345 fits into 3050 8 times, leaving a remainder of 290.
Write down 8 as next digit of the result. 
Result so far: 289228.4318
Deduct 2760 from 3050 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 13:
The number 345 fits into 2900 8 times, leaving a remainder of 140.
Write down 8 as next digit of the result. 
Result so far: 289228.43188
Subtract 2760 from 2900 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 289228.43188 with a remainder of 0.00014.
