We look at the division of 373243 by 87 
We're looking to find how many times 87 goes into 373243.

Moving on to step 1:
If we divide 3 by 87, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 87

Let's proceed to step 2:
87 goes into 37 0 times with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 87

Advancing to step 3:
87 goes into 373 4 times with a remainder of 25.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 348 from 373 leaves us with 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 87

Going ahead to step 4:
252 divided by 87 is 2 with a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we take 174 away from 252, we end up with 78.
Take the next digit (4) from the dividend and append it to 78, then repeat: 784 / 87

Step 5:
784 divided by 87 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 429.0
Subtracting 783 from 784 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 87

Let's proceed to step 6:
The number 87 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 4290.0
Deduct 0 from 13 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
87 can be fit into 130 1 times, resulting in a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 4290.1
Subtracting 87 from 130 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 8:
The number 87 fits into 430 4 times, leaving a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 4290.14
Subtract 348 from 430 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
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: 4290.149
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.

On to step 10:
87 can be fit into 370 4 times, resulting in a remainder of 22.
The next digit of our result is 4. 
Result so far: 4290.1494
The remainder is 22 after subtracting 348 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
87 can be fit into 220 2 times, resulting in a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 4290.14942
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.

Step 12:
87 can be fit into 460 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 4290.149425
The remainder is 25 after subtracting 435 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
If we divide 250 by 87, we get 2 and a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 4290.1494252
Deduct 174 from 250 and we're left with 76.
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 14:
87 goes into 760 8 times with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 4290.14942528
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.

The final result is 4290.14942528 with a remainder of 6.4e-08.
