438154 divided by 87 
Let's see how many times 87 fits into 438154.

On to step 1:
When dividing 4 by 87, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 87

Advancing to step 2:
87 can be fit into 43 0 times, resulting in a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 87

On to step 3:
438 divided by 87 is 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 435 from 438 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 87

Step 4:
87 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we subtract 0 from 31, we get 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 87

Advancing to step 5:
The number 87 fits into 315 3 times, leaving a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 503.0
Deduct 261 from 315 and we're left with 54.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 87

Step 6:
87 can be fit into 544 6 times, resulting in a remainder of 22.
The next digit of our result is 6. 
Result so far: 5036.0
Deduct 522 from 544 and we're left 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.

Advancing to step 7:
87 can be fit into 220 2 times, resulting in a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 5036.2
If we take 174 away from 220, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
The number 87 fits into 460 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 5036.25
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.

Let's proceed to step 9:
87 can be fit into 250 2 times, resulting in a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 5036.252
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.

Let's proceed to step 10:
When dividing 760 by 87, we get 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 5036.2528
If we take 696 away from 760, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
If we divide 640 by 87, we get 7 and a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 5036.25287
Subtract 609 from 640 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 12:
87 goes into 310 3 times with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 5036.252873
Subtract 261 from 310 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 13:
490 divided by 87 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 5036.2528735
If we subtract 435 from 490, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 14:
When dividing 550 by 87, we get 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 5036.25287356
Subtract 522 from 550 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 5036.25287356 and a remainder of 2.8e-08.
