We look at the division of 64000845 by 991 
We want to figure out the number of times 64000845 can be divided by 991.

Going ahead to step 1:
The number 991 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 991

On to step 2:
The number 991 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 991

Let's proceed to step 3:
When dividing 640 by 991, we get 0 with a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 640 leaves us with 640.
Take the next digit (0) from the dividend and append it to 640, then repeat: 6400 / 991

Step 4:
If we divide 6400 by 991, we get 6 and a remainder of 454.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 5946 from 6400 to get 454.
Grab the next digit (0) from the dividend, add it to 454, then carry on: 4540 / 991

Let's proceed to step 5:
If we divide 4540 by 991, we get 4 and a remainder of 576.
The next digit of our result is 4. 
Result so far: 64.0
If we take 3964 away from 4540, we end up with 576.
Append the next digit (8) from the dividend to 576 and continue with: 5768 / 991

On to step 6:
5768 divided by 991 is 5 with a remainder of 813.
The number 5 becomes the next digit in our result. 
Result so far: 645.0
If we subtract 4955 from 5768, we get 813.
Append the next digit (4) from the dividend to 813 and continue with: 8134 / 991

Moving on to step 7:
The number 991 fits into 8134 8 times, leaving a remainder of 206.
Use 8 as the next digit of our solution. 
Result so far: 6458.0
The remainder is 206 after subtracting 7928 from 8134.
Fetch the next digit (5) from the dividend, attach it to 206 and continue: 2065 / 991

Advancing to step 8:
The number 991 fits into 2065 2 times, leaving a remainder of 83.
Use 2 as the next digit of our solution. 
Result so far: 64582.0
If we take 1982 away from 2065, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 9:
991 goes into 830 0 times with a remainder of 830.
Record the quotient 0 as the next digit in the result. 
Result so far: 64582.0
If we subtract 0 from 830, we get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Going ahead to step 10:
8300 divided by 991 is 8 with a remainder of 372.
Put 8 as the next digit of the answer. 
Result so far: 64582.08
Subtract 7928 from 8300 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 11:
991 goes into 3720 3 times with a remainder of 747.
The number 3 becomes the next digit in our result. 
Result so far: 64582.083
The remainder is 747 after subtracting 2973 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7470, and continue the process.

Going ahead to step 12:
991 can be fit into 7470 7 times, resulting in a remainder of 533.
Record the quotient 7 as the next digit in the result. 
Result so far: 64582.0837
The remainder is 533 after subtracting 6937 from 7470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Going ahead to step 13:
If we divide 5330 by 991, we get 5 and a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 64582.08375
Subtract 4955 from 5330 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 14:
If we divide 3750 by 991, we get 3 and a remainder of 777.
Record the quotient 3 as the next digit in the result. 
Result so far: 64582.083753
Subtracting 2973 from 3750 leaves us with 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Going ahead to step 15:
991 goes into 7770 7 times with a remainder of 833.
Use 7 as the next digit of our solution. 
Result so far: 64582.0837537
Subtracting 6937 from 7770 leaves us with 833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8330, and continue the process.

On to step 16:
If we divide 8330 by 991, we get 8 and a remainder of 402.
Put 8 as the next digit of the answer. 
Result so far: 64582.08375378
Subtracting 7928 from 8330 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Our division results in 64582.08375378 with a remaining 4.02e-07.
