Fetch the next digit (1) from the dividend, attach it to 487 and continue: 4871 / 621

Going ahead to step 6:
If we divide 4871 by 621, we get 7 and a remainder of 524.
The next digit of our result is 7. 
Result so far: 417.0
If we take 4347 away from 4871, we end up with 524.
Take the next digit (5) from the dividend and append it to 524, then repeat: 5245 / 621

Going ahead to step 7:
621 can be fit into 5245 8 times, resulting in a remainder of 277.
The next digit of our result is 8. 
Result so far: 4178.0
The remainder is 277 after subtracting 4968 from 5245.
Include the next digit (3) from the dividend after 277, then repeat: 2773 / 621

Advancing to step 8:
The number 621 fits into 2773 4 times, leaving a remainder of 289.
Record the quotient 4 as the next digit in the result. 
Result so far: 41784.0
Subtracting 2484 from 2773 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 9:
The number 621 fits into 2890 4 times, leaving a remainder of 406.
Put 4 as the next digit of the answer. 
Result so far: 41784.4
Subtracting 2484 from 2890 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 10:
621 goes into 4060 6 times with a remainder of 334.
The number 6 becomes the next digit in our result. 
Result so far: 41784.46
The remainder is 334 after subtracting 3726 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Advancing to step 11:
The number 621 fits into 3340 5 times, leaving a remainder of 235.
Write down 5 as next digit of the result. 
Result so far: 41784.465
Subtracting 3105 from 3340 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 12:
The number 621 fits into 2350 3 times, leaving a remainder of 487.
Write down 3 as next digit of the result. 
Result so far: 41784.4653
If we subtract 1863 from 2350, we get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Moving on to step 13:
If we divide 4870 by 621, we get 7 and a remainder of 523.
The number 7 becomes the next digit in our result. 
Result so far: 41784.46537
Deduct 4347 from 4870 and we're left with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Moving on to step 14:
When dividing 5230 by 621, we get 8 with a remainder of 262.
The next digit of our result is 8. 
Result so far: 41784.465378
Deduct 4968 from 5230 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 15:
621 goes into 2620 4 times with a remainder of 136.
Write down 4 as next digit of the result. 
Result so far: 41784.4653784
Deduct 2484 from 2620 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 16:
1360 divided by 621 is 2 with a remainder of 118.
Put 2 as the next digit of the answer. 
Result so far: 41784.46537842
Subtract 1242 from 1360 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

In conclusion, the division gives 41784.46537842 with a balance of 1.18e-07.
