78376317 divided by 566 
Our goal is to divide 78376317 by 566.

Advancing to step 1:
7 divided by 566 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 566

Going ahead to step 2:
566 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 566

On to step 3:
566 can be fit into 783 1 times, resulting in a remainder of 217.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 566 from 783 and we're left with 217.
Take the next digit (7) from the dividend and append it to 217, then repeat: 2177 / 566

On to step 4:
566 can be fit into 2177 3 times, resulting in a remainder of 479.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1698 from 2177, we get 479.
Append the next digit (6) from the dividend to 479 and continue with: 4796 / 566

Moving on to step 5:
When dividing 4796 by 566, we get 8 with a remainder of 268.
Put 8 as the next digit of the answer. 
Result so far: 138.0
If we take 4528 away from 4796, we end up with 268.
Include the next digit (3) from the dividend after 268, then repeat: 2683 / 566

Advancing to step 6:
566 goes into 2683 4 times with a remainder of 419.
Use 4 as the next digit of our solution. 
Result so far: 1384.0
If we subtract 2264 from 2683, we get 419.
Bring next digit (1) of the dividend behind the 419 and repeat the process: 4191 / 566

Step 7:
566 goes into 4191 7 times with a remainder of 229.
Put 7 as the next digit of the answer. 
Result so far: 13847.0
Subtracting 3962 from 4191 leaves us with 229.
Bring next digit (7) of the dividend behind the 229 and repeat the process: 2297 / 566

Advancing to step 8:
566 can be fit into 2297 4 times, resulting in a remainder of 33.
The next digit of our result is 4. 
Result so far: 138474.0
Subtracting 2264 from 2297 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
The number 566 fits into 330 0 times, leaving a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 138474.0
If we subtract 0 from 330, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 10:
The number 566 fits into 3300 5 times, leaving a remainder of 470.
The next digit of our result is 5. 
Result so far: 138474.05
Subtract 2830 from 3300 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 11:
566 can be fit into 4700 8 times, resulting in a remainder of 172.
The next digit of our result is 8. 
Result so far: 138474.058
If we take 4528 away from 4700, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 12:
When dividing 1720 by 566, we get 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 138474.0583
If we subtract 1698 from 1720, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
The number 566 fits into 220 0 times, leaving a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 138474.0583
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 14:
When dividing 2200 by 566, we get 3 with a remainder of 502.
Put 3 as the next digit of the answer. 
Result so far: 138474.058303
If we subtract 1698 from 2200, we get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Step 15:
The number 566 fits into 5020 8 times, leaving a remainder of 492.
Put 8 as the next digit of the answer. 
Result so far: 138474.0583038
Subtract 4528 from 5020 to get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Let's proceed to step 16:
If we divide 4920 by 566, we get 8 and a remainder of 392.
Write down 8 as next digit of the result. 
Result so far: 138474.05830388
Subtract 4528 from 4920 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

In conclusion, the division gives 138474.05830388 with a balance of 3.92e-07.
