Let's divide 57143001 by 778
We want to figure out the number of times 57143001 can be divided by 778.

Step 1:
778 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 778

On to step 2:
57 divided by 778 is 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Take the next digit (1) from the dividend and append it to 57, then repeat: 571 / 778

Advancing to step 3:
778 can be fit into 571 0 times, resulting in a remainder of 571.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 571 and we're left with 571.
Include the next digit (4) from the dividend after 571, then repeat: 5714 / 778

Going ahead to step 4:
The number 778 fits into 5714 7 times, leaving a remainder of 268.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 5446 from 5714, we get 268.
Include the next digit (3) from the dividend after 268, then repeat: 2683 / 778

Moving on to step 5:
778 can be fit into 2683 3 times, resulting in a remainder of 349.
Write down 3 as next digit of the result. 
Result so far: 73.0
Subtracting 2334 from 2683 leaves us with 349.
Grab the next digit (0) from the dividend, add it to 349, then carry on: 3490 / 778

Step 6:
If we divide 3490 by 778, we get 4 and a remainder of 378.
The next digit of our result is 4. 
Result so far: 734.0
Subtract 3112 from 3490 to get 378.
Fetch the next digit (0) from the dividend, attach it to 378 and continue: 3780 / 778

Advancing to step 7:
The number 778 fits into 3780 4 times, leaving a remainder of 668.
Put 4 as the next digit of the answer. 
Result so far: 7344.0
Subtracting 3112 from 3780 leaves us with 668.
Include the next digit (1) from the dividend after 668, then repeat: 6681 / 778

Let's proceed to step 8:
When dividing 6681 by 778, we get 8 with a remainder of 457.
The number 8 becomes the next digit in our result. 
Result so far: 73448.0
If we subtract 6224 from 6681, we get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Step 9:
4570 divided by 778 is 5 with a remainder of 680.
The next digit of our result is 5. 
Result so far: 73448.5
The remainder is 680 after subtracting 3890 from 4570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 10:
6800 divided by 778 is 8 with a remainder of 576.
Put 8 as the next digit of the answer. 
Result so far: 73448.58
Subtract 6224 from 6800 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 11:
778 goes into 5760 7 times with a remainder of 314.
Write down 7 as next digit of the result. 
Result so far: 73448.587
Deduct 5446 from 5760 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 12:
If we divide 3140 by 778, we get 4 and a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 73448.5874
Subtract 3112 from 3140 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
778 can be fit into 280 0 times, resulting in a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 73448.5874
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 14:
The number 778 fits into 2800 3 times, leaving a remainder of 466.
Put 3 as the next digit of the answer. 
Result so far: 73448.587403
Subtracting 2334 from 2800 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Let's proceed to step 15:
When dividing 4660 by 778, we get 5 with a remainder of 770.
Write down 5 as next digit of the result. 
Result so far: 73448.5874035
Subtract 3890 from 4660 to get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

On to step 16:
778 can be fit into 7700 9 times, resulting in a remainder of 698.
Use 9 as the next digit of our solution. 
Result so far: 73448.58740359
If we take 7002 away from 7700, we end up with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

After the division, we end up with 73448.58740359 and a remainder of 6.98e-07.
