We look at the division of 80691377 by 64 
We're looking to find how many times 64 goes into 80691377.

Let's proceed to step 1:
64 goes into 8 0 times with 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.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 64

Let's proceed to step 2:
80 divided by 64 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 64 away from 80, we end up with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 64

Going ahead to step 3:
64 goes into 166 2 times with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 128 from 166 leaves us with 38.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 64

Step 4:
The number 64 fits into 389 6 times, leaving a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtract 384 from 389 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 64

Advancing to step 5:
51 divided by 64 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 1260.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 64

Step 6:
The number 64 fits into 513 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 12608.0
If we subtract 512 from 513, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 64

Step 7:
If we divide 17 by 64, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 126080.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 64

Moving on to step 8:
64 goes into 177 2 times with a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 1260802.0
If we subtract 128 from 177, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
490 divided by 64 is 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 1260802.7
If we take 448 away from 490, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
420 divided by 64 is 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 1260802.76
If we subtract 384 from 420, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
If we divide 360 by 64, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 1260802.765
Deduct 320 from 360 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
400 divided by 64 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 1260802.7656
If we subtract 384 from 400, 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.

Advancing to step 13:
If we divide 160 by 64, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 1260802.76562
Deduct 128 from 160 and we're left 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.

Going ahead to step 14:
320 divided by 64 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1260802.765625
If we subtract 320 from 320, we 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.

Moving on to step 15:
When dividing 0 by 64, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1260802.765625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 16:
The number 64 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1260802.765625
If we subtract 0 from 0, we 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.

Our division results in 1260802.765625 with a remaining 0.0.
