78305430 divided by 506 
We're looking to find how many times 506 goes into 78305430.

Step 1:
506 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 506

On to step 2:
The number 506 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 506

Step 3:
The number 506 fits into 783 1 times, leaving a remainder of 277.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 506 away from 783, we end up with 277.
Take the next digit (0) from the dividend and append it to 277, then repeat: 2770 / 506

Advancing to step 4:
2770 divided by 506 is 5 with a remainder of 240.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 240 after subtracting 2530 from 2770.
Append the next digit (5) from the dividend to 240 and continue with: 2405 / 506

Let's proceed to step 5:
The number 506 fits into 2405 4 times, leaving a remainder of 381.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
Subtracting 2024 from 2405 leaves us with 381.
Take the next digit (4) from the dividend and append it to 381, then repeat: 3814 / 506

Let's proceed to step 6:
506 can be fit into 3814 7 times, resulting in a remainder of 272.
Record the quotient 7 as the next digit in the result. 
Result so far: 1547.0
If we take 3542 away from 3814, we end up with 272.
Append the next digit (3) from the dividend to 272 and continue with: 2723 / 506

Moving on to step 7:
506 can be fit into 2723 5 times, resulting in a remainder of 193.
Put 5 as the next digit of the answer. 
Result so far: 15475.0
Deduct 2530 from 2723 and we're left with 193.
Fetch the next digit (0) from the dividend, attach it to 193 and continue: 1930 / 506

On to step 8:
The number 506 fits into 1930 3 times, leaving a remainder of 412.
Use 3 as the next digit of our solution. 
Result so far: 154753.0
Subtract 1518 from 1930 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 9:
506 goes into 4120 8 times with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 154753.8
The remainder is 72 after subtracting 4048 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
506 goes into 720 1 times with a remainder of 214.
Put 1 as the next digit of the answer. 
Result so far: 154753.81
Subtract 506 from 720 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 11:
When dividing 2140 by 506, we get 4 with a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 154753.814
Deduct 2024 from 2140 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 12:
506 can be fit into 1160 2 times, resulting in a remainder of 148.
The next digit of our result is 2. 
Result so far: 154753.8142
Deduct 1012 from 1160 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 13:
The number 506 fits into 1480 2 times, leaving a remainder of 468.
The number 2 becomes the next digit in our result. 
Result so far: 154753.81422
Subtracting 1012 from 1480 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

After the division, we end up with 154753.81422 and a remainder of 0.000468.
