42509818 divided by 287 
Let's see how many times 287 fits into 42509818.

Going ahead to step 1:
4 divided by 287 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 287

Step 2:
42 divided by 287 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 287

On to step 3:
287 can be fit into 425 1 times, resulting in a remainder of 138.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 287 from 425 leaves us with 138.
Take the next digit (0) from the dividend and append it to 138, then repeat: 1380 / 287

Going ahead to step 4:
1380 divided by 287 is 4 with a remainder of 232.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 232 after subtracting 1148 from 1380.
Append the next digit (9) from the dividend to 232 and continue with: 2329 / 287

Going ahead to step 5:
If we divide 2329 by 287, we get 8 and a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 148.0
If we take 2296 away from 2329, we end up with 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 287

On to step 6:
287 can be fit into 338 1 times, resulting in a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 1481.0
If we take 287 away from 338, we end up with 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 287

Moving on to step 7:
If we divide 511 by 287, we get 1 and a remainder of 224.
Write down 1 as next digit of the result. 
Result so far: 14811.0
If we subtract 287 from 511, we get 224.
Take the next digit (8) from the dividend and append it to 224, then repeat: 2248 / 287

Moving on to step 8:
287 can be fit into 2248 7 times, resulting in a remainder of 239.
Record the quotient 7 as the next digit in the result. 
Result so far: 148117.0
Subtracting 2009 from 2248 leaves us 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.

Going ahead to step 9:
2390 divided by 287 is 8 with a remainder of 94.
Record the quotient 8 as the next digit in the result. 
Result so far: 148117.8
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.

Step 10:
287 goes into 940 3 times with a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 148117.83
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.

Advancing to step 11:
If we divide 790 by 287, we get 2 and a remainder of 216.
Write down 2 as next digit of the result. 
Result so far: 148117.832
If we take 574 away from 790, we end up 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.

Going ahead to step 12:
The number 287 fits into 2160 7 times, leaving a remainder of 151.
Record the quotient 7 as the next digit in the result. 
Result so far: 148117.8327
If we take 2009 away from 2160, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Advancing to step 13:
If we divide 1510 by 287, we get 5 and a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 148117.83275
Subtracting 1435 from 1510 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 14:
287 goes into 750 2 times with a remainder of 176.
Put 2 as the next digit of the answer. 
Result so far: 148117.832752
Deduct 574 from 750 and we're left 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.

Advancing to step 15:
1760 divided by 287 is 6 with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 148117.8327526
Subtracting 1722 from 1760 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 16:
If we divide 380 by 287, we get 1 and a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 148117.83275261
If we take 287 away from 380, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

The quotient of the division is 148117.83275261, and the remainder is 9.3e-08.
