69199865 ÷ 778 
Our goal is to divide 69199865 by 778.

Step 1:
6 divided by 778 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 778

Moving on to step 2:
778 can be fit into 69 0 times, resulting in a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 778

Advancing to step 3:
778 goes into 691 0 times with a remainder of 691.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 691 after subtracting 0 from 691.
Take the next digit (9) from the dividend and append it to 691, then repeat: 6919 / 778

Moving on to step 4:
778 goes into 6919 8 times with a remainder of 695.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 6224 from 6919 to get 695.
Grab the next digit (9) from the dividend, add it to 695, then carry on: 6959 / 778

On to step 5:
778 can be fit into 6959 8 times, resulting in a remainder of 735.
The next digit of our result is 8. 
Result so far: 88.0
Subtracting 6224 from 6959 leaves us with 735.
Include the next digit (8) from the dividend after 735, then repeat: 7358 / 778

Advancing to step 6:
778 goes into 7358 9 times with a remainder of 356.
The next digit of our result is 9. 
Result so far: 889.0
If we take 7002 away from 7358, we end up with 356.
Grab the next digit (6) from the dividend, add it to 356, then carry on: 3566 / 778

On to step 7:
The number 778 fits into 3566 4 times, leaving a remainder of 454.
The number 4 becomes the next digit in our result. 
Result so far: 8894.0
If we subtract 3112 from 3566, we get 454.
Bring next digit (5) of the dividend behind the 454 and repeat the process: 4545 / 778

On to step 8:
When dividing 4545 by 778, we get 5 with a remainder of 655.
Write down 5 as next digit of the result. 
Result so far: 88945.0
Subtracting 3890 from 4545 leaves us with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

On to step 9:
The number 778 fits into 6550 8 times, leaving a remainder of 326.
Put 8 as the next digit of the answer. 
Result so far: 88945.8
The remainder is 326 after subtracting 6224 from 6550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 10:
778 can be fit into 3260 4 times, resulting in a remainder of 148.
The next digit of our result is 4. 
Result so far: 88945.84
If we take 3112 away from 3260, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 11:
The number 778 fits into 1480 1 times, leaving a remainder of 702.
Use 1 as the next digit of our solution. 
Result so far: 88945.841
Subtract 778 from 1480 to get 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Going ahead to step 12:
When dividing 7020 by 778, we get 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 88945.8419
Deduct 7002 from 7020 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
If we divide 180 by 778, we get 0 and a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 88945.8419
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 14:
If we divide 1800 by 778, we get 2 and a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 88945.841902
Subtract 1556 from 1800 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 15:
When dividing 2440 by 778, we get 3 with a remainder of 106.
Put 3 as the next digit of the answer. 
Result so far: 88945.8419023
The remainder is 106 after subtracting 2334 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 16:
When dividing 1060 by 778, we get 1 with a remainder of 282.
Put 1 as the next digit of the answer. 
Result so far: 88945.84190231
Deduct 778 from 1060 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

The final result is 88945.84190231 with a remainder of 2.82e-07.
