We're dividing 404397 by 87 
We're looking to find how many times 87 goes into 404397.

Advancing to step 1:
87 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 87

On to step 2:
87 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 87

Going ahead to step 3:
When dividing 404 by 87, we get 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 348 from 404 leaves us with 56.
Fetch the next digit (3) from the dividend, attach it to 56 and continue: 563 / 87

Let's proceed to step 4:
If we divide 563 by 87, we get 6 and a remainder of 41.
The next digit of our result is 6. 
Result so far: 46.0
If we take 522 away from 563, we end up with 41.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 87

On to step 5:
When dividing 419 by 87, we get 4 with a remainder of 71.
Record the quotient 4 as the next digit in the result. 
Result so far: 464.0
Subtracting 348 from 419 leaves us with 71.
Take the next digit (7) from the dividend and append it to 71, then repeat: 717 / 87

Let's proceed to step 6:
87 goes into 717 8 times with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 4648.0
Deduct 696 from 717 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
The number 87 fits into 210 2 times, leaving a remainder of 36.
The next digit of our result is 2. 
Result so far: 4648.2
If we take 174 away from 210, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
87 can be fit into 360 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4648.24
If we subtract 348 from 360, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
87 can be fit into 120 1 times, resulting in a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 4648.241
If we take 87 away from 120, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
330 divided by 87 is 3 with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 4648.2413
Deduct 261 from 330 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 11:
87 goes into 690 7 times with a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 4648.24137
If we subtract 609 from 690, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 12:
When dividing 810 by 87, we get 9 with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 4648.241379
Subtract 783 from 810 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 13:
The number 87 fits into 270 3 times, leaving a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 4648.2413793
Subtract 261 from 270 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
90 divided by 87 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 4648.24137931
Subtracting 87 from 90 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 4648.24137931, and the remainder is 3e-09.
