78233953 ÷ 135 
Our goal is to divide 78233953 by 135.

Moving on to step 1:
The number 135 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 135

Let's proceed to step 2:
When dividing 78 by 135, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 135

On to step 3:
The number 135 fits into 782 5 times, leaving a remainder of 107.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 675 from 782 and we're left with 107.
Grab the next digit (3) from the dividend, add it to 107, then carry on: 1073 / 135

Going ahead to step 4:
135 can be fit into 1073 7 times, resulting in a remainder of 128.
Write down 7 as next digit of the result. 
Result so far: 57.0
Deduct 945 from 1073 and we're left with 128.
Include the next digit (3) from the dividend after 128, then repeat: 1283 / 135

Moving on to step 5:
135 goes into 1283 9 times with a remainder of 68.
The number 9 becomes the next digit in our result. 
Result so far: 579.0
Deduct 1215 from 1283 and we're left with 68.
Grab the next digit (9) from the dividend, add it to 68, then carry on: 689 / 135

On to step 6:
135 goes into 689 5 times with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 5795.0
Subtracting 675 from 689 leaves us with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 135

Moving on to step 7:
145 divided by 135 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 57951.0
Deduct 135 from 145 and we're left with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 135

Let's proceed to step 8:
The number 135 fits into 103 0 times, leaving a remainder of 103.
Write down 0 as next digit of the result. 
Result so far: 579510.0
Subtracting 0 from 103 leaves us 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.

Moving on to step 9:
135 can be fit into 1030 7 times, resulting in a remainder of 85.
Write down 7 as next digit of the result. 
Result so far: 579510.7
Subtracting 945 from 1030 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 10:
The number 135 fits into 850 6 times, leaving a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 579510.76
Subtracting 810 from 850 leaves us 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.

Moving on to step 11:
The number 135 fits into 400 2 times, leaving a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 579510.762
Deduct 270 from 400 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 12:
1300 divided by 135 is 9 with a remainder of 85.
Write down 9 as next digit of the result. 
Result so far: 579510.7629
The remainder is 85 after subtracting 1215 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 13:
The number 135 fits into 850 6 times, leaving a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 579510.76296
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.

On to step 14:
135 goes into 400 2 times with a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 579510.762962
The remainder is 130 after subtracting 270 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 15:
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: 579510.7629629
If we take 1215 away from 1300, we end up with 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 16:
850 divided by 135 is 6 with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 579510.76296296
Deduct 810 from 850 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.

The quotient of the division is 579510.76296296, and the remainder is 4e-08.
