Let's divide 39589545 by 64
We want to figure out the number of times 39589545 can be divided by 64.

Step 1:
64 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 64

Going ahead to step 2:
When dividing 39 by 64, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 64

Step 3:
When dividing 395 by 64, we get 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 384 from 395 to get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 64

Going ahead to step 4:
The number 64 fits into 118 1 times, leaving a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Subtracting 64 from 118 leaves us with 54.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 64

On to step 5:
The number 64 fits into 549 8 times, leaving a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 618.0
Subtract 512 from 549 to get 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 64

Step 6:
64 can be fit into 375 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 6185.0
Deduct 320 from 375 and we're left with 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 64

Let's proceed to step 7:
If we divide 554 by 64, we get 8 and a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 61858.0
Deduct 512 from 554 and we're left with 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 64

Going ahead to step 8:
The number 64 fits into 425 6 times, leaving a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 618586.0
If we subtract 384 from 425, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 9:
When dividing 410 by 64, we get 6 with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 618586.6
If we take 384 away from 410, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
64 goes into 260 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 618586.64
Deduct 256 from 260 and we're left 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.

Step 11:
64 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 618586.64
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
The number 64 fits into 400 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 618586.6406
If we subtract 384 from 400, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
If we divide 160 by 64, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 618586.64062
If we take 128 away from 160, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
64 goes into 320 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 618586.640625
If we subtract 320 from 320, 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 15:
64 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 618586.640625
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.

On to step 16:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 618586.640625
Subtracting 0 from 0 leaves us 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 618586.640625 and a remainder of 0.0.
