641578 ÷ 7 
We want to divide 641578 by 7.

Moving on to step 1:
7 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 7

Advancing to step 2:
64 divided by 7 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 63 away from 64, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 7

Going ahead to step 3:
7 can be fit into 11 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
The remainder is 4 after subtracting 7 from 11.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 7

Step 4:
45 divided by 7 is 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 916.0
If we take 42 away from 45, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 7

Moving on to step 5:
The number 7 fits into 37 5 times, leaving a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 9165.0
If we take 35 away from 37, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 7

Let's proceed to step 6:
7 can be fit into 28 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 91654.0
If we subtract 28 from 28, 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.

On to step 7:
If we divide 0 by 7, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 91654.0
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.

Step 8:
When dividing 0 by 7, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 91654.0
Subtract 0 from 0 to 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.

Our division results in 91654.0 with a remaining 0.0.
