We look at the division of 30783012 by 68 
Let's see how many times 68 fits into 30783012.

Step 1:
If we divide 3 by 68, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 68

Going ahead to step 2:
68 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 68

Let's proceed to step 3:
68 goes into 307 4 times with a remainder of 35.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 272 away from 307, we end up with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 68

Let's proceed to step 4:
If we divide 358 by 68, we get 5 and a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 340 from 358 to get 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 68

On to step 5:
If we divide 183 by 68, we get 2 and a remainder of 47.
Record the quotient 2 as the next digit in the result. 
Result so far: 452.0
Deduct 136 from 183 and we're left with 47.
Take the next digit (0) from the dividend and append it to 47, then repeat: 470 / 68

On to step 6:
470 divided by 68 is 6 with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 4526.0
If we subtract 408 from 470, we get 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 68

Moving on to step 7:
68 goes into 621 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 45269.0
Subtract 612 from 621 to get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 68

Moving on to step 8:
If we divide 92 by 68, we get 1 and a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 452691.0
Deduct 68 from 92 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
If we divide 240 by 68, we get 3 and a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 452691.3
Subtracting 204 from 240 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
When dividing 360 by 68, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 452691.35
Subtract 340 from 360 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
If we divide 200 by 68, we get 2 and a remainder of 64.
The next digit of our result is 2. 
Result so far: 452691.352
If we subtract 136 from 200, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
68 can be fit into 640 9 times, resulting in a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 452691.3529
Deduct 612 from 640 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
If we divide 280 by 68, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 452691.35294
If we subtract 272 from 280, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
80 divided by 68 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 452691.352941
The remainder is 12 after subtracting 68 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 15:
68 goes into 120 1 times with a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 452691.3529411
If we subtract 68 from 120, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 452691.3529411 with a balance of 5.2e-07.
