81657745 ÷ 778 
We want to figure out the number of times 81657745 can be divided by 778.

Going ahead to step 1:
778 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 778

Going ahead to step 2:
81 divided by 778 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 778

Let's proceed to step 3:
If we divide 816 by 778, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 778 from 816 to get 38.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 778

Going ahead to step 4:
385 divided by 778 is 0 with a remainder of 385.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 385 and we're left with 385.
Bring next digit (7) of the dividend behind the 385 and repeat the process: 3857 / 778

Moving on to step 5:
3857 divided by 778 is 4 with a remainder of 745.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Deduct 3112 from 3857 and we're left with 745.
Grab the next digit (7) from the dividend, add it to 745, then carry on: 7457 / 778

Advancing to step 6:
If we divide 7457 by 778, we get 9 and a remainder of 455.
The number 9 becomes the next digit in our result. 
Result so far: 1049.0
If we subtract 7002 from 7457, we get 455.
Bring next digit (4) of the dividend behind the 455 and repeat the process: 4554 / 778

Moving on to step 7:
778 can be fit into 4554 5 times, resulting in a remainder of 664.
The next digit of our result is 5. 
Result so far: 10495.0
If we take 3890 away from 4554, we end up with 664.
Take the next digit (5) from the dividend and append it to 664, then repeat: 6645 / 778

Step 8:
When dividing 6645 by 778, we get 8 with a remainder of 421.
Record the quotient 8 as the next digit in the result. 
Result so far: 104958.0
If we take 6224 away from 6645, we end up with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Let's proceed to step 9:
When dividing 4210 by 778, we get 5 with a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 104958.5
Deduct 3890 from 4210 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 10:
3200 divided by 778 is 4 with a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 104958.54
If we take 3112 away from 3200, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 11:
778 can be fit into 880 1 times, resulting in a remainder of 102.
Put 1 as the next digit of the answer. 
Result so far: 104958.541
Subtracting 778 from 880 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 12:
778 goes into 1020 1 times with a remainder of 242.
Put 1 as the next digit of the answer. 
Result so far: 104958.5411
If we subtract 778 from 1020, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Our division results in 104958.5411 with a remaining 0.00242.
