43903 divided by 87 
We want to divide 43903 by 87.

Let's proceed to step 1:
87 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 87

Going ahead to step 2:
87 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 87

Step 3:
87 can be fit into 439 5 times, resulting in a remainder of 4.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 435 from 439 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 87

Going ahead to step 4:
The number 87 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 40 and we're left with 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 87

Going ahead to step 5:
When dividing 403 by 87, we get 4 with a remainder of 55.
Put 4 as the next digit of the answer. 
Result so far: 504.0
If we take 348 away from 403, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 6:
The number 87 fits into 550 6 times, leaving a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 504.6
If we take 522 away from 550, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
If we divide 280 by 87, we get 3 and a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 504.63
If we take 261 away from 280, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 8:
The number 87 fits into 190 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 504.632
Subtract 174 from 190 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
When dividing 160 by 87, we get 1 with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 504.6321
If we take 87 away from 160, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 10:
The number 87 fits into 730 8 times, leaving a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 504.63218
If we subtract 696 from 730, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
340 divided by 87 is 3 with a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 504.632183
Subtracting 261 from 340 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 12:
790 divided by 87 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 504.6321839
Subtract 783 from 790 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
87 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 504.6321839
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 504.6321839, and the remainder is 7e-08.
