The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 3858 from 4167 and we're left with 309.
Include the next digit (0) from the dividend after 309, then repeat: 3090 / 643

Going ahead to step 5:
When dividing 3090 by 643, we get 4 with a remainder of 518.
The next digit of our result is 4. 
Result so far: 64.0
Deduct 2572 from 3090 and we're left with 518.
Take the next digit (9) from the dividend and append it to 518, then repeat: 5189 / 643

Let's proceed to step 6:
When dividing 5189 by 643, we get 8 with a remainder of 45.
Use 8 as the next digit of our solution. 
Result so far: 648.0
If we take 5144 away from 5189, we end up with 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 643

Let's proceed to step 7:
643 can be fit into 454 0 times, resulting in a remainder of 454.
Write down 0 as next digit of the result. 
Result so far: 6480.0
Deduct 0 from 454 and we're left with 454.
Fetch the next digit (2) from the dividend, attach it to 454 and continue: 4542 / 643

Going ahead to step 8:
643 can be fit into 4542 7 times, resulting in a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 64807.0
If we subtract 4501 from 4542, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 9:
If we divide 410 by 643, we get 0 and a remainder of 410.
The number 0 becomes the next digit in our result. 
Result so far: 64807.0
If we subtract 0 from 410, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 10:
4100 divided by 643 is 6 with a remainder of 242.
Use 6 as the next digit of our solution. 
Result so far: 64807.06
Subtracting 3858 from 4100 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Moving on to step 11:
643 goes into 2420 3 times with a remainder of 491.
Use 3 as the next digit of our solution. 
Result so far: 64807.063
Subtract 1929 from 2420 to get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

On to step 12:
The number 643 fits into 4910 7 times, leaving a remainder of 409.
Record the quotient 7 as the next digit in the result. 
Result so far: 64807.0637
The remainder is 409 after subtracting 4501 from 4910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Moving on to step 13:
4090 divided by 643 is 6 with a remainder of 232.
Write down 6 as next digit of the result. 
Result so far: 64807.06376
If we take 3858 away from 4090, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 14:
643 goes into 2320 3 times with a remainder of 391.
The next digit of our result is 3. 
Result so far: 64807.063763
Deduct 1929 from 2320 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Going ahead to step 15:
When dividing 3910 by 643, we get 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 64807.0637636
The remainder is 52 after subtracting 3858 from 3910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 16:
If we divide 520 by 643, we get 0 and a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 64807.0637636
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

In conclusion, the division gives 64807.0637636 with a balance of 5.2e-07.
