We look at the division of 43103 by 87 
Let's see how many times 87 fits into 43103.

Moving on to step 1:
87 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of 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

On to step 2:
If we divide 43 by 87, we get 0 and a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 87

Advancing to step 3:
When dividing 431 by 87, we get 4 with a remainder of 83.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 348 from 431 leaves us with 83.
Grab the next digit (0) from the dividend, add it to 83, then carry on: 830 / 87

Advancing to step 4:
If we divide 830 by 87, we get 9 and a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtracting 783 from 830 leaves us with 47.
Grab the next digit (3) from the dividend, add it to 47, then carry on: 473 / 87

Moving on to step 5:
The number 87 fits into 473 5 times, leaving a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 495.0
Deduct 435 from 473 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 6:
380 divided by 87 is 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 495.4
If we subtract 348 from 380, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
The number 87 fits into 320 3 times, leaving a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 495.43
Subtract 261 from 320 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 8:
87 can be fit into 590 6 times, resulting in a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 495.436
Deduct 522 from 590 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
87 goes into 680 7 times with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 495.4367
The remainder is 71 after subtracting 609 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 10:
When dividing 710 by 87, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 495.43678
If we take 696 away from 710, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
The number 87 fits into 140 1 times, leaving a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 495.436781
Subtract 87 from 140 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 12:
If we divide 530 by 87, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 495.4367816
If we subtract 522 from 530, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
87 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 495.4367816
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 495.4367816, with a leftover of 8e-08.
