77879703 ÷ 143 
Our goal is to divide 77879703 by 143.

Advancing to step 1:
When dividing 7 by 143, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 143

Advancing to step 2:
When dividing 77 by 143, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 143

Moving on to step 3:
143 can be fit into 778 5 times, resulting in a remainder of 63.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 63 after subtracting 715 from 778.
Include the next digit (7) from the dividend after 63, then repeat: 637 / 143

Let's proceed to step 4:
143 can be fit into 637 4 times, resulting in a remainder of 65.
The next digit of our result is 4. 
Result so far: 54.0
Subtract 572 from 637 to get 65.
Grab the next digit (9) from the dividend, add it to 65, then carry on: 659 / 143

Moving on to step 5:
The number 143 fits into 659 4 times, leaving a remainder of 87.
The number 4 becomes the next digit in our result. 
Result so far: 544.0
Subtracting 572 from 659 leaves us with 87.
Include the next digit (7) from the dividend after 87, then repeat: 877 / 143

On to step 6:
If we divide 877 by 143, we get 6 and a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 5446.0
Subtract 858 from 877 to get 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 143

Step 7:
143 can be fit into 190 1 times, resulting in a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 54461.0
The remainder is 47 after subtracting 143 from 190.
Grab the next digit (3) from the dividend, add it to 47, then carry on: 473 / 143

Going ahead to step 8:
143 can be fit into 473 3 times, resulting in a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 544613.0
Subtracting 429 from 473 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
143 goes into 440 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 544613.3
Subtract 429 from 440 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
When dividing 110 by 143, we get 0 with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 544613.3
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 11:
143 can be fit into 1100 7 times, resulting in a remainder of 99.
The next digit of our result is 7. 
Result so far: 544613.307
Deduct 1001 from 1100 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 12:
If we divide 990 by 143, we get 6 and a remainder of 132.
The next digit of our result is 6. 
Result so far: 544613.3076
Deduct 858 from 990 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 13:
When dividing 1320 by 143, we get 9 with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 544613.30769
Subtract 1287 from 1320 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 14:
The number 143 fits into 330 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 544613.307692
Deduct 286 from 330 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 15:
When dividing 440 by 143, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 544613.3076923
If we take 429 away from 440, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 16:
The number 143 fits into 110 0 times, leaving a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 544613.3076923
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final result is 544613.3076923 with a remainder of 1.1e-07.
