We're dividing 381925 by 87 
Let's see how many times 87 fits into 381925.

Step 1:
The number 87 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 87

Let's proceed to step 2:
If we divide 38 by 87, we get 0 and a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 87

On to step 3:
87 can be fit into 381 4 times, resulting in a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 33 after subtracting 348 from 381.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 87

On to step 4:
If we divide 339 by 87, we get 3 and a remainder of 78.
The next digit of our result is 3. 
Result so far: 43.0
If we subtract 261 from 339, we get 78.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 87

Moving on to step 5:
When dividing 782 by 87, we get 8 with a remainder of 86.
The next digit of our result is 8. 
Result so far: 438.0
The remainder is 86 after subtracting 696 from 782.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 87

Let's proceed to step 6:
865 divided by 87 is 9 with a remainder of 82.
The next digit of our result is 9. 
Result so far: 4389.0
Deduct 783 from 865 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 7:
If we divide 820 by 87, we get 9 and a remainder of 37.
The next digit of our result is 9. 
Result so far: 4389.9
Subtract 783 from 820 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
If we divide 370 by 87, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 4389.94
Subtracting 348 from 370 leaves us with 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 9:
87 goes into 220 2 times with a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 4389.942
If we subtract 174 from 220, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
87 goes into 460 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 4389.9425
If we subtract 435 from 460, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
250 divided by 87 is 2 with a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 4389.94252
The remainder is 76 after subtracting 174 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
When dividing 760 by 87, we get 8 with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 4389.942528
Subtract 696 from 760 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
The number 87 fits into 640 7 times, leaving a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 4389.9425287
If we take 609 away from 640, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 14:
310 divided by 87 is 3 with a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 4389.94252873
Deduct 261 from 310 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 4389.94252873 with a remainder of 4.9e-08.
