We divide 641879 by 8
Let's see how many times 8 fits into 641879.

Advancing to step 1:
8 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 8

Step 2:
8 can be fit into 64 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 64 from 64 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 8

Going ahead to step 3:
8 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 80.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 8

Step 4:
8 goes into 18 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 802.0
Subtracting 16 from 18 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 8

Advancing to step 5:
8 goes into 27 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 8023.0
If we subtract 24 from 27, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 8

Moving on to step 6:
If we divide 39 by 8, we get 4 and a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 80234.0
Deduct 32 from 39 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 8 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 80234.8
Deduct 64 from 70 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
8 goes into 60 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 80234.87
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
When dividing 40 by 8, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 80234.875
If we take 40 away from 40, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 80234.875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 80234.875
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 80234.875 and a remainder of 0.0.
