4397425 ÷ 287 
We want to divide 4397425 by 287.

On to step 1:
If we divide 4 by 287, we get 0 and 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.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 287

Moving on to step 2:
287 goes into 43 0 times with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 287

Going ahead to step 3:
287 goes into 439 1 times with a remainder of 152.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 287 from 439, we get 152.
Grab the next digit (7) from the dividend, add it to 152, then carry on: 1527 / 287

Moving on to step 4:
1527 divided by 287 is 5 with a remainder of 92.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 1435 from 1527 to get 92.
Append the next digit (4) from the dividend to 92 and continue with: 924 / 287

On to step 5:
924 divided by 287 is 3 with a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
The remainder is 63 after subtracting 861 from 924.
Include the next digit (2) from the dividend after 63, then repeat: 632 / 287

Moving on to step 6:
287 goes into 632 2 times with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 1532.0
Subtracting 574 from 632 leaves us with 58.
Fetch the next digit (5) from the dividend, attach it to 58 and continue: 585 / 287

Moving on to step 7:
287 can be fit into 585 2 times, resulting in a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 15322.0
Subtract 574 from 585 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
287 goes into 110 0 times with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 15322.0
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.

Step 9:
If we divide 1100 by 287, we get 3 and a remainder of 239.
Write down 3 as next digit of the result. 
Result so far: 15322.03
Subtracting 861 from 1100 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 10:
287 can be fit into 2390 8 times, resulting in a remainder of 94.
Use 8 as the next digit of our solution. 
Result so far: 15322.038
If we take 2296 away from 2390, we end up 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 11:
287 can be fit into 940 3 times, resulting in a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 15322.0383
The remainder is 79 after subtracting 861 from 940.
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 12:
The number 287 fits into 790 2 times, leaving a remainder of 216.
Write down 2 as next digit of the result. 
Result so far: 15322.03832
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 13:
287 can be fit into 2160 7 times, resulting in a remainder of 151.
Put 7 as the next digit of the answer. 
Result so far: 15322.038327
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.

Let's proceed to step 14:
287 can be fit into 1510 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 15322.0383275
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.

Let's proceed to step 15:
287 can be fit into 750 2 times, resulting in a remainder of 176.
Record the quotient 2 as the next digit in the result. 
Result so far: 15322.03832752
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.

After the division, we end up with 15322.03832752 and a remainder of 1.76e-07.
