We look at the division of 80645846 by 64 
We want to divide 80645846 by 64.

Going ahead to step 1:
The number 64 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 64

Advancing to step 2:
64 goes into 80 1 times with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 16 after subtracting 64 from 80.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 64

Advancing to step 3:
When dividing 166 by 64, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 128 from 166, we get 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 64

Going ahead to step 4:
64 goes into 384 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 126.0
If we take 384 away from 384, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 64

Moving on to step 5:
When dividing 5 by 64, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 1260.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 64

Moving on to step 6:
If we divide 58 by 64, we get 0 and a remainder of 58.
The next digit of our result is 0. 
Result so far: 12600.0
If we take 0 away from 58, we end up with 58.
Grab the next digit (4) from the dividend, add it to 58, then carry on: 584 / 64

Moving on to step 7:
64 can be fit into 584 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 126009.0
Subtract 576 from 584 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 64

Going ahead to step 8:
The number 64 fits into 86 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1260091.0
If we take 64 away from 86, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
64 can be fit into 220 3 times, resulting in a remainder of 28.
The next digit of our result is 3. 
Result so far: 1260091.3
If we subtract 192 from 220, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
64 can be fit into 280 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 1260091.34
Deduct 256 from 280 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
64 goes into 240 3 times with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 1260091.343
If we take 192 away from 240, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
If we divide 480 by 64, we get 7 and a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 1260091.3437
Subtracting 448 from 480 leaves us 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.

Let's proceed to step 13:
320 divided by 64 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1260091.34375
Deduct 320 from 320 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 14:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1260091.34375
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.

Step 15:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1260091.34375
Subtract 0 from 0 to 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.

The quotient of the division is 1260091.34375, and the remainder is 0.0.
