80318563 ÷ 427 
Our goal is to divide 80318563 by 427.

Let's proceed to step 1:
The number 427 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 427

Going ahead to step 2:
427 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 427

Moving on to step 3:
The number 427 fits into 803 1 times, leaving a remainder of 376.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 427 from 803 to get 376.
Include the next digit (1) from the dividend after 376, then repeat: 3761 / 427

Step 4:
3761 divided by 427 is 8 with a remainder of 345.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtracting 3416 from 3761 leaves us with 345.
Grab the next digit (8) from the dividend, add it to 345, then carry on: 3458 / 427

On to step 5:
3458 divided by 427 is 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 188.0
Subtracting 3416 from 3458 leaves us with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 427

Step 6:
427 goes into 425 0 times with a remainder of 425.
Record the quotient 0 as the next digit in the result. 
Result so far: 1880.0
Subtracting 0 from 425 leaves us with 425.
Fetch the next digit (6) from the dividend, attach it to 425 and continue: 4256 / 427

On to step 7:
4256 divided by 427 is 9 with a remainder of 413.
Put 9 as the next digit of the answer. 
Result so far: 18809.0
Subtracting 3843 from 4256 leaves us with 413.
Fetch the next digit (3) from the dividend, attach it to 413 and continue: 4133 / 427

Advancing to step 8:
427 can be fit into 4133 9 times, resulting in a remainder of 290.
The number 9 becomes the next digit in our result. 
Result so far: 188099.0
The remainder is 290 after subtracting 3843 from 4133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 9:
If we divide 2900 by 427, we get 6 and a remainder of 338.
Record the quotient 6 as the next digit in the result. 
Result so far: 188099.6
Subtract 2562 from 2900 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 10:
The number 427 fits into 3380 7 times, leaving a remainder of 391.
The number 7 becomes the next digit in our result. 
Result so far: 188099.67
Deduct 2989 from 3380 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 11:
3910 divided by 427 is 9 with a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 188099.679
Subtracting 3843 from 3910 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 12:
When dividing 670 by 427, we get 1 with a remainder of 243.
Use 1 as the next digit of our solution. 
Result so far: 188099.6791
Subtracting 427 from 670 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 13:
When dividing 2430 by 427, we get 5 with a remainder of 295.
The next digit of our result is 5. 
Result so far: 188099.67915
The remainder is 295 after subtracting 2135 from 2430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 14:
The number 427 fits into 2950 6 times, leaving a remainder of 388.
Use 6 as the next digit of our solution. 
Result so far: 188099.679156
Subtracting 2562 from 2950 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 15:
The number 427 fits into 3880 9 times, leaving a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 188099.6791569
Deduct 3843 from 3880 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 16:
427 goes into 370 0 times with a remainder of 370.
The number 0 becomes the next digit in our result. 
Result so far: 188099.6791569
Subtracting 0 from 370 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

In conclusion, the division gives 188099.6791569 with a balance of 3.7e-07.
