Let's divide 39764436 by 641
We're looking to find how many times 641 goes into 39764436.

On to step 1:
The number 641 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 641

On to step 2:
641 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 641

Let's proceed to step 3:
397 divided by 641 is 0 with a remainder of 397.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 397 and we're left with 397.
Fetch the next digit (6) from the dividend, attach it to 397 and continue: 3976 / 641

Let's proceed to step 4:
The number 641 fits into 3976 6 times, leaving a remainder of 130.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 3846 from 3976 and we're left with 130.
Grab the next digit (4) from the dividend, add it to 130, then carry on: 1304 / 641

Moving on to step 5:
641 goes into 1304 2 times with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
If we subtract 1282 from 1304, we get 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 641

On to step 6:
641 can be fit into 224 0 times, resulting in a remainder of 224.
The next digit of our result is 0. 
Result so far: 620.0
If we take 0 away from 224, we end up with 224.
Fetch the next digit (3) from the dividend, attach it to 224 and continue: 2243 / 641

Let's proceed to step 7:
641 can be fit into 2243 3 times, resulting in a remainder of 320.
Write down 3 as next digit of the result. 
Result so far: 6203.0
Subtract 1923 from 2243 to get 320.
Take the next digit (6) from the dividend and append it to 320, then repeat: 3206 / 641

Moving on to step 8:
When dividing 3206 by 641, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 62035.0
If we subtract 3205 from 3206, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
10 divided by 641 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 62035.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
100 divided by 641 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 62035.0
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 62035.0 and a remainder of 0.1.
