64521095 divided by 791 
We want to figure out the number of times 64521095 can be divided by 791.

Going ahead to step 1:
6 divided by 791 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 791

Going ahead to step 2:
The number 791 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 791

Let's proceed to step 3:
The number 791 fits into 645 0 times, leaving a remainder of 645.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 645 and we're left with 645.
Append the next digit (2) from the dividend to 645 and continue with: 6452 / 791

Advancing to step 4:
6452 divided by 791 is 8 with a remainder of 124.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 6328 from 6452, we get 124.
Take the next digit (1) from the dividend and append it to 124, then repeat: 1241 / 791

Step 5:
If we divide 1241 by 791, we get 1 and a remainder of 450.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we subtract 791 from 1241, we get 450.
Include the next digit (0) from the dividend after 450, then repeat: 4500 / 791

Let's proceed to step 6:
The number 791 fits into 4500 5 times, leaving a remainder of 545.
Put 5 as the next digit of the answer. 
Result so far: 815.0
If we subtract 3955 from 4500, we get 545.
Take the next digit (9) from the dividend and append it to 545, then repeat: 5459 / 791

Step 7:
When dividing 5459 by 791, we get 6 with a remainder of 713.
The number 6 becomes the next digit in our result. 
Result so far: 8156.0
The remainder is 713 after subtracting 4746 from 5459.
Bring next digit (5) of the dividend behind the 713 and repeat the process: 7135 / 791

Moving on to step 8:
791 can be fit into 7135 9 times, resulting in a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 81569.0
If we subtract 7119 from 7135, 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 9:
If we divide 160 by 791, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 81569.0
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
791 can be fit into 1600 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 81569.02
Subtract 1582 from 1600 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
When dividing 180 by 791, we get 0 with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 81569.02
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
791 can be fit into 1800 2 times, resulting in a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 81569.0202
The remainder is 218 after subtracting 1582 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 13:
If we divide 2180 by 791, we get 2 and a remainder of 598.
Write down 2 as next digit of the result. 
Result so far: 81569.02022
Deduct 1582 from 2180 and we're left with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

After the division, we end up with 81569.02022 and a remainder of 0.000598.
