6458067 ÷ 641 
Let's see how many times 641 fits into 6458067.

Step 1:
6 divided by 641 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 641

Step 2:
64 divided by 641 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (5) from the dividend and append it to 64, then repeat: 645 / 641

Going ahead to step 3:
645 divided by 641 is 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 641 from 645, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 641

Going ahead to step 4:
641 goes into 48 0 times with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 48, we end up with 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 641

On to step 5:
641 goes into 480 0 times with a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 480 and we're left with 480.
Fetch the next digit (6) from the dividend, attach it to 480 and continue: 4806 / 641

Going ahead to step 6:
4806 divided by 641 is 7 with a remainder of 319.
The next digit of our result is 7. 
Result so far: 1007.0
Deduct 4487 from 4806 and we're left with 319.
Append the next digit (7) from the dividend to 319 and continue with: 3197 / 641

Step 7:
If we divide 3197 by 641, we get 4 and a remainder of 633.
The number 4 becomes the next digit in our result. 
Result so far: 10074.0
The remainder is 633 after subtracting 2564 from 3197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Let's proceed to step 8:
If we divide 6330 by 641, we get 9 and a remainder of 561.
Record the quotient 9 as the next digit in the result. 
Result so far: 10074.9
Deduct 5769 from 6330 and we're left with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

On to step 9:
The number 641 fits into 5610 8 times, leaving a remainder of 482.
The number 8 becomes the next digit in our result. 
Result so far: 10074.98
If we subtract 5128 from 5610, we get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 10:
If we divide 4820 by 641, we get 7 and a remainder of 333.
Write down 7 as next digit of the result. 
Result so far: 10074.987
Subtract 4487 from 4820 to get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Let's proceed to step 11:
When dividing 3330 by 641, we get 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 10074.9875
If we take 3205 away from 3330, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 12:
If we divide 1250 by 641, we get 1 and a remainder of 609.
Put 1 as the next digit of the answer. 
Result so far: 10074.98751
If we subtract 641 from 1250, we get 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Advancing to step 13:
641 goes into 6090 9 times with a remainder of 321.
Use 9 as the next digit of our solution. 
Result so far: 10074.987519
The remainder is 321 after subtracting 5769 from 6090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 14:
3210 divided by 641 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 10074.9875195
If we subtract 3205 from 3210, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 15:
50 divided by 641 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 10074.9875195
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 10074.9875195 with a remainder of 5e-08.
