We're dividing 355043 by 87 
We're looking to find how many times 87 goes into 355043.

Let's proceed to step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 87

Advancing to step 2:
35 divided by 87 is 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 87

On to step 3:
If we divide 355 by 87, we get 4 and a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 348 away from 355, we end up with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 87

Step 4:
87 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 40.0
If we subtract 0 from 70, we get 70.
Append the next digit (4) from the dividend to 70 and continue with: 704 / 87

On to step 5:
87 goes into 704 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 408.0
The remainder is 8 after subtracting 696 from 704.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 87

Moving on to step 6:
83 divided by 87 is 0 with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 4080.0
If we take 0 away from 83, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 7:
When dividing 830 by 87, we get 9 with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 4080.9
If we take 783 away from 830, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 8:
470 divided by 87 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 4080.95
Subtracting 435 from 470 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
The number 87 fits into 350 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 4080.954
Subtract 348 from 350 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
87 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4080.954
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
200 divided by 87 is 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 4080.95402
Subtract 174 from 200 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
260 divided by 87 is 2 with a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 4080.954022
If we subtract 174 from 260, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 4080.954022 with a remainder of 8.6e-06.
