Let's divide 8640778 by 135
We're looking to find how many times 135 goes into 8640778.

Step 1:
8 divided by 135 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 135

Going ahead to step 2:
135 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Grab the next digit (4) from the dividend, add it to 86, then carry on: 864 / 135

Advancing to step 3:
The number 135 fits into 864 6 times, leaving a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 810 away from 864, we end up with 54.
Bring next digit (0) of the dividend behind the 54 and repeat the process: 540 / 135

Moving on to step 4:
135 can be fit into 540 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 64.0
The remainder is 0 after subtracting 540 from 540.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 135

Moving on to step 5:
135 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 640.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 135

Moving on to step 6:
If we divide 77 by 135, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 6400.0
Subtract 0 from 77 to get 77.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 135

Let's proceed to step 7:
778 divided by 135 is 5 with a remainder of 103.
Record the quotient 5 as the next digit in the result. 
Result so far: 64005.0
Deduct 675 from 778 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 8:
If we divide 1030 by 135, we get 7 and a remainder of 85.
The next digit of our result is 7. 
Result so far: 64005.7
The remainder is 85 after subtracting 945 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 9:
135 goes into 850 6 times with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 64005.76
If we subtract 810 from 850, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
135 can be fit into 400 2 times, resulting in a remainder of 130.
Record the quotient 2 as the next digit in the result. 
Result so far: 64005.762
Subtract 270 from 400 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 11:
The number 135 fits into 1300 9 times, leaving a remainder of 85.
Put 9 as the next digit of the answer. 
Result so far: 64005.7629
Subtract 1215 from 1300 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 12:
The number 135 fits into 850 6 times, leaving a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 64005.76296
Subtract 810 from 850 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
When dividing 400 by 135, we get 2 with a remainder of 130.
The next digit of our result is 2. 
Result so far: 64005.762962
If we subtract 270 from 400, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 14:
135 can be fit into 1300 9 times, resulting in a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 64005.7629629
If we subtract 1215 from 1300, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 15:
The number 135 fits into 850 6 times, leaving a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 64005.76296296
If we take 810 away from 850, we end up 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.

The final outcome is 64005.76296296, with a leftover of 4e-08.
