78714719 ÷ 553 
Our goal is to divide 78714719 by 553.

Going ahead to step 1:
When dividing 7 by 553, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 553

Going ahead to step 2:
553 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 553

Going ahead to step 3:
The number 553 fits into 787 1 times, leaving a remainder of 234.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 553 from 787, we get 234.
Include the next digit (1) from the dividend after 234, then repeat: 2341 / 553

Advancing to step 4:
If we divide 2341 by 553, we get 4 and a remainder of 129.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 2212 away from 2341, we end up with 129.
Include the next digit (4) from the dividend after 129, then repeat: 1294 / 553

On to step 5:
When dividing 1294 by 553, we get 2 with a remainder of 188.
Put 2 as the next digit of the answer. 
Result so far: 142.0
Subtract 1106 from 1294 to get 188.
Append the next digit (7) from the dividend to 188 and continue with: 1887 / 553

Moving on to step 6:
The number 553 fits into 1887 3 times, leaving a remainder of 228.
Write down 3 as next digit of the result. 
Result so far: 1423.0
Subtracting 1659 from 1887 leaves us with 228.
Include the next digit (1) from the dividend after 228, then repeat: 2281 / 553

Let's proceed to step 7:
553 goes into 2281 4 times with a remainder of 69.
Write down 4 as next digit of the result. 
Result so far: 14234.0
The remainder is 69 after subtracting 2212 from 2281.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 553

Step 8:
When dividing 699 by 553, we get 1 with a remainder of 146.
The number 1 becomes the next digit in our result. 
Result so far: 142341.0
Subtracting 553 from 699 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 9:
553 can be fit into 1460 2 times, resulting in a remainder of 354.
Put 2 as the next digit of the answer. 
Result so far: 142341.2
Subtracting 1106 from 1460 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 10:
553 can be fit into 3540 6 times, resulting in a remainder of 222.
Use 6 as the next digit of our solution. 
Result so far: 142341.26
Deduct 3318 from 3540 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 11:
2220 divided by 553 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 142341.264
If we take 2212 away from 2220, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
553 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 142341.264
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
553 goes into 800 1 times with a remainder of 247.
Put 1 as the next digit of the answer. 
Result so far: 142341.26401
If we subtract 553 from 800, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Step 14:
The number 553 fits into 2470 4 times, leaving a remainder of 258.
Record the quotient 4 as the next digit in the result. 
Result so far: 142341.264014
Subtract 2212 from 2470 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 15:
The number 553 fits into 2580 4 times, leaving a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 142341.2640144
The remainder is 368 after subtracting 2212 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Our division results in 142341.2640144 with a remaining 3.68e-06.
