80822454 ÷ 964 
We want to figure out the number of times 80822454 can be divided by 964.

On to step 1:
When dividing 8 by 964, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 964

Let's proceed to step 2:
The number 964 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 964

Moving on to step 3:
964 can be fit into 808 0 times, resulting in a remainder of 808.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 808 leaves us with 808.
Include the next digit (2) from the dividend after 808, then repeat: 8082 / 964

On to step 4:
The number 964 fits into 8082 8 times, leaving a remainder of 370.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 7712 from 8082 to get 370.
Bring next digit (2) of the dividend behind the 370 and repeat the process: 3702 / 964

Advancing to step 5:
964 can be fit into 3702 3 times, resulting in a remainder of 810.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtract 2892 from 3702 to get 810.
Append the next digit (4) from the dividend to 810 and continue with: 8104 / 964

Let's proceed to step 6:
The number 964 fits into 8104 8 times, leaving a remainder of 392.
Put 8 as the next digit of the answer. 
Result so far: 838.0
If we subtract 7712 from 8104, we get 392.
Grab the next digit (5) from the dividend, add it to 392, then carry on: 3925 / 964

Going ahead to step 7:
964 goes into 3925 4 times with a remainder of 69.
Write down 4 as next digit of the result. 
Result so far: 8384.0
The remainder is 69 after subtracting 3856 from 3925.
Bring next digit (4) of the dividend behind the 69 and repeat the process: 694 / 964

Step 8:
When dividing 694 by 964, we get 0 with a remainder of 694.
Write down 0 as next digit of the result. 
Result so far: 83840.0
If we subtract 0 from 694, we get 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Let's proceed to step 9:
964 goes into 6940 7 times with a remainder of 192.
Put 7 as the next digit of the answer. 
Result so far: 83840.7
If we subtract 6748 from 6940, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 10:
When dividing 1920 by 964, we get 1 with a remainder of 956.
The number 1 becomes the next digit in our result. 
Result so far: 83840.71
Deduct 964 from 1920 and we're left with 956.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9560, and continue the process.

On to step 11:
When dividing 9560 by 964, we get 9 with a remainder of 884.
Put 9 as the next digit of the answer. 
Result so far: 83840.719
Subtracting 8676 from 9560 leaves us with 884.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8840, and continue the process.

Let's proceed to step 12:
If we divide 8840 by 964, we get 9 and a remainder of 164.
Write down 9 as next digit of the result. 
Result so far: 83840.7199
The remainder is 164 after subtracting 8676 from 8840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The final result is 83840.7199 with a remainder of 0.00164.
