42340547 ÷ 287 
Our goal is to divide 42340547 by 287.

Going ahead to step 1:
If we divide 4 by 287, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 287

Going ahead to step 2:
287 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 287

Moving on to step 3:
287 goes into 423 1 times with a remainder of 136.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 287 from 423, we get 136.
Take the next digit (4) from the dividend and append it to 136, then repeat: 1364 / 287

Step 4:
The number 287 fits into 1364 4 times, leaving a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 1148 from 1364, we get 216.
Fetch the next digit (0) from the dividend, attach it to 216 and continue: 2160 / 287

Moving on to step 5:
287 goes into 2160 7 times with a remainder of 151.
Use 7 as the next digit of our solution. 
Result so far: 147.0
Subtract 2009 from 2160 to get 151.
Include the next digit (5) from the dividend after 151, then repeat: 1515 / 287

On to step 6:
287 can be fit into 1515 5 times, resulting in a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 1475.0
The remainder is 80 after subtracting 1435 from 1515.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 287

Moving on to step 7:
804 divided by 287 is 2 with a remainder of 230.
The next digit of our result is 2. 
Result so far: 14752.0
If we subtract 574 from 804, we get 230.
Take the next digit (7) from the dividend and append it to 230, then repeat: 2307 / 287

Moving on to step 8:
The number 287 fits into 2307 8 times, leaving a remainder of 11.
The next digit of our result is 8. 
Result so far: 147528.0
If we take 2296 away from 2307, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
If we divide 110 by 287, we get 0 and a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 147528.0
Subtracting 0 from 110 leaves us 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.

Going ahead to step 10:
The number 287 fits into 1100 3 times, leaving a remainder of 239.
The next digit of our result is 3. 
Result so far: 147528.03
If we take 861 away from 1100, we end up with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 11:
When dividing 2390 by 287, we get 8 with a remainder of 94.
Use 8 as the next digit of our solution. 
Result so far: 147528.038
Subtracting 2296 from 2390 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 12:
940 divided by 287 is 3 with a remainder of 79.
The next digit of our result is 3. 
Result so far: 147528.0383
If we subtract 861 from 940, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 13:
If we divide 790 by 287, we get 2 and a remainder of 216.
Use 2 as the next digit of our solution. 
Result so far: 147528.03832
Deduct 574 from 790 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 14:
287 can be fit into 2160 7 times, resulting in a remainder of 151.
Use 7 as the next digit of our solution. 
Result so far: 147528.038327
Subtract 2009 from 2160 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 15:
287 goes into 1510 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 147528.0383275
The remainder is 75 after subtracting 1435 from 1510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 16:
When dividing 750 by 287, we get 2 with a remainder of 176.
The next digit of our result is 2. 
Result so far: 147528.03832752
If we take 574 away from 750, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

In conclusion, the division gives 147528.03832752 with a balance of 1.76e-07.
