We look at the division of 66887810 by 215 
Let's see how many times 215 fits into 66887810.

On to step 1:
If we divide 6 by 215, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 215

Step 2:
The number 215 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 215

On to step 3:
215 can be fit into 668 3 times, resulting in a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 645 from 668 leaves us with 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 215

Step 4:
When dividing 238 by 215, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 215 from 238, we get 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 215

Step 5:
When dividing 237 by 215, we get 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 311.0
If we subtract 215 from 237, we get 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 215

Going ahead to step 6:
215 goes into 228 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 3111.0
Subtract 215 from 228 to get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 215

On to step 7:
The number 215 fits into 131 0 times, leaving a remainder of 131.
The number 0 becomes the next digit in our result. 
Result so far: 31110.0
The remainder is 131 after subtracting 0 from 131.
Fetch the next digit (0) from the dividend, attach it to 131 and continue: 1310 / 215

Step 8:
When dividing 1310 by 215, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 311106.0
Subtract 1290 from 1310 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.

Let's proceed to step 9:
215 can be fit into 200 0 times, resulting in a remainder of 200.
The next digit of our result is 0. 
Result so far: 311106.0
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 10:
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: 311106.09
If we subtract 1935 from 2000, we get 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 11:
650 divided by 215 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 311106.093
Subtracting 645 from 650 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
215 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 311106.093
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 13:
The number 215 fits into 500 2 times, leaving a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 311106.09302
Deduct 430 from 500 and we're left 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.

Advancing to step 14:
700 divided by 215 is 3 with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 311106.093023
Subtracting 645 from 700 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 15:
215 can be fit into 550 2 times, resulting in a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 311106.0930232
Deduct 430 from 550 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 16:
When dividing 1200 by 215, we get 5 with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 311106.09302325
The remainder is 125 after subtracting 1075 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

In conclusion, the division gives 311106.09302325 with a balance of 1.25e-07.
