81882787 ÷ 215 
We want to figure out the number of times 81882787 can be divided by 215.

Moving on to step 1:
If we divide 8 by 215, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 215

Going ahead to step 2:
If we divide 81 by 215, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Grab the next digit (8) from the dividend, add it to 81, then carry on: 818 / 215

Step 3:
215 goes into 818 3 times with a remainder of 173.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 645 from 818 leaves us with 173.
Bring next digit (8) of the dividend behind the 173 and repeat the process: 1738 / 215

Advancing to step 4:
215 goes into 1738 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 38.0
Deduct 1720 from 1738 and we're left with 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 215

Let's proceed to step 5:
If we divide 182 by 215, we get 0 and a remainder of 182.
Put 0 as the next digit of the answer. 
Result so far: 380.0
Deduct 0 from 182 and we're left with 182.
Fetch the next digit (7) from the dividend, attach it to 182 and continue: 1827 / 215

On to step 6:
215 goes into 1827 8 times with a remainder of 107.
The next digit of our result is 8. 
Result so far: 3808.0
Deduct 1720 from 1827 and we're left with 107.
Fetch the next digit (8) from the dividend, attach it to 107 and continue: 1078 / 215

Going ahead to step 7:
The number 215 fits into 1078 5 times, leaving a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 38085.0
Subtract 1075 from 1078 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 215

Going ahead to step 8:
215 goes into 37 0 times with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 380850.0
Subtract 0 from 37 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
The number 215 fits into 370 1 times, leaving a remainder of 155.
The number 1 becomes the next digit in our result. 
Result so far: 380850.1
Subtract 215 from 370 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 10:
1550 divided by 215 is 7 with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 380850.17
If we subtract 1505 from 1550, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
The number 215 fits into 450 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 380850.172
Subtract 430 from 450 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
The number 215 fits into 200 0 times, leaving a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 380850.172
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 13:
The number 215 fits into 2000 9 times, leaving a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 380850.17209
Deduct 1935 from 2000 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 14:
215 can be fit into 650 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 380850.172093
The remainder is 5 after subtracting 645 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 15:
215 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 380850.172093
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 16:
The number 215 fits into 500 2 times, leaving a remainder of 70.
The next digit of our result is 2. 
Result so far: 380850.17209302
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 380850.17209302 with a remainder of 7e-08.
