We're dividing 64388876 by 641 
We want to divide 64388876 by 641.

Advancing to step 1:
641 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 641

Going ahead to step 2:
The number 641 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 641

Let's proceed to step 3:
If we divide 643 by 641, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 641 from 643 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 641

Going ahead to step 4:
When dividing 28 by 641, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 28 after subtracting 0 from 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 641

Let's proceed to step 5:
641 goes into 288 0 times with a remainder of 288.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 288 leaves us with 288.
Include the next digit (8) from the dividend after 288, then repeat: 2888 / 641

Step 6:
When dividing 2888 by 641, we get 4 with a remainder of 324.
Put 4 as the next digit of the answer. 
Result so far: 1004.0
If we take 2564 away from 2888, we end up with 324.
Take the next digit (7) from the dividend and append it to 324, then repeat: 3247 / 641

Moving on to step 7:
641 can be fit into 3247 5 times, resulting in a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 10045.0
If we subtract 3205 from 3247, we get 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 641

Advancing to step 8:
If we divide 426 by 641, we get 0 and a remainder of 426.
The number 0 becomes the next digit in our result. 
Result so far: 100450.0
If we take 0 away from 426, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 9:
4260 divided by 641 is 6 with a remainder of 414.
Use 6 as the next digit of our solution. 
Result so far: 100450.6
The remainder is 414 after subtracting 3846 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 10:
If we divide 4140 by 641, we get 6 and a remainder of 294.
Use 6 as the next digit of our solution. 
Result so far: 100450.66
Deduct 3846 from 4140 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

The quotient of the division is 100450.66, and the remainder is 0.294.
