On to step 5:
When dividing 2267 by 639, we get 3 with a remainder of 350.
Put 3 as the next digit of the answer. 
Result so far: 133.0
If we take 1917 away from 2267, we end up with 350.
Append the next digit (4) from the dividend to 350 and continue with: 3504 / 639

Moving on to step 6:
639 goes into 3504 5 times with a remainder of 309.
Write down 5 as next digit of the result. 
Result so far: 1335.0
If we subtract 3195 from 3504, we get 309.
Take the next digit (7) from the dividend and append it to 309, then repeat: 3097 / 639

Advancing to step 7:
3097 divided by 639 is 4 with a remainder of 541.
Record the quotient 4 as the next digit in the result. 
Result so far: 13354.0
If we take 2556 away from 3097, we end up with 541.
Append the next digit (2) from the dividend to 541 and continue with: 5412 / 639

Advancing to step 8:
5412 divided by 639 is 8 with a remainder of 300.
Write down 8 as next digit of the result. 
Result so far: 133548.0
If we take 5112 away from 5412, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 9:
The number 639 fits into 3000 4 times, leaving a remainder of 444.
Write down 4 as next digit of the result. 
Result so far: 133548.4
Deduct 2556 from 3000 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 10:
The number 639 fits into 4440 6 times, leaving a remainder of 606.
Use 6 as the next digit of our solution. 
Result so far: 133548.46
The remainder is 606 after subtracting 3834 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

On to step 11:
If we divide 6060 by 639, we get 9 and a remainder of 309.
The next digit of our result is 9. 
Result so far: 133548.469
If we subtract 5751 from 6060, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 12:
639 goes into 3090 4 times with a remainder of 534.
Write down 4 as next digit of the result. 
Result so far: 133548.4694
Subtract 2556 from 3090 to get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Let's proceed to step 13:
When dividing 5340 by 639, we get 8 with a remainder of 228.
Write down 8 as next digit of the result. 
Result so far: 133548.46948
Subtract 5112 from 5340 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 14:
The number 639 fits into 2280 3 times, leaving a remainder of 363.
Record the quotient 3 as the next digit in the result. 
Result so far: 133548.469483
The remainder is 363 after subtracting 1917 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Step 15:
639 goes into 3630 5 times with a remainder of 435.
Put 5 as the next digit of the answer. 
Result so far: 133548.4694835
Subtract 3195 from 3630 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 16:
When dividing 4350 by 639, we get 6 with a remainder of 516.
Use 6 as the next digit of our solution. 
Result so far: 133548.46948356
Deduct 3834 from 4350 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

In conclusion, the division gives 133548.46948356 with a balance of 5.16e-07.
