64716551 divided by 791 
We want to figure out the number of times 64716551 can be divided by 791.

Moving on to step 1:
791 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 791

Advancing to step 2:
64 divided by 791 is 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (7) from the dividend, add it to 64, then carry on: 647 / 791

Going ahead to step 3:
When dividing 647 by 791, we get 0 with a remainder of 647.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 647 and we're left with 647.
Bring next digit (1) of the dividend behind the 647 and repeat the process: 6471 / 791

On to step 4:
When dividing 6471 by 791, we get 8 with a remainder of 143.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 6328 away from 6471, we end up with 143.
Append the next digit (6) from the dividend to 143 and continue with: 1436 / 791

Let's proceed to step 5:
The number 791 fits into 1436 1 times, leaving a remainder of 645.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtract 791 from 1436 to get 645.
Fetch the next digit (5) from the dividend, attach it to 645 and continue: 6455 / 791

Going ahead to step 6:
791 can be fit into 6455 8 times, resulting in a remainder of 127.
The next digit of our result is 8. 
Result so far: 818.0
Subtract 6328 from 6455 to get 127.
Fetch the next digit (5) from the dividend, attach it to 127 and continue: 1275 / 791

Let's proceed to step 7:
791 goes into 1275 1 times with a remainder of 484.
Write down 1 as next digit of the result. 
Result so far: 8181.0
Subtract 791 from 1275 to get 484.
Bring next digit (1) of the dividend behind the 484 and repeat the process: 4841 / 791

Advancing to step 8:
791 goes into 4841 6 times with a remainder of 95.
Record the quotient 6 as the next digit in the result. 
Result so far: 81816.0
Deduct 4746 from 4841 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 9:
If we divide 950 by 791, we get 1 and a remainder of 159.
The next digit of our result is 1. 
Result so far: 81816.1
Subtract 791 from 950 to get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 10:
1590 divided by 791 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 81816.12
Subtracting 1582 from 1590 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
If we divide 80 by 791, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 81816.12
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
When dividing 800 by 791, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 81816.1201
If we subtract 791 from 800, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
90 divided by 791 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 81816.1201
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 14:
900 divided by 791 is 1 with a remainder of 109.
Record the quotient 1 as the next digit in the result. 
Result so far: 81816.120101
Subtracting 791 from 900 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 15:
When dividing 1090 by 791, we get 1 with a remainder of 299.
Use 1 as the next digit of our solution. 
Result so far: 81816.1201011
The remainder is 299 after subtracting 791 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

After the division, we end up with 81816.1201011 and a remainder of 2.99e-06.
