66016376 divided by 215 
Our goal is to divide 66016376 by 215.

Going ahead to step 1:
When dividing 6 by 215, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 215

Advancing to step 2:
215 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (0) from the dividend after 66, then repeat: 660 / 215

On to step 3:
215 can be fit into 660 3 times, resulting in a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 645 from 660 to get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 215

On to step 4:
When dividing 151 by 215, we get 0 with a remainder of 151.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 151 after subtracting 0 from 151.
Take the next digit (6) from the dividend and append it to 151, then repeat: 1516 / 215

Let's proceed to step 5:
If we divide 1516 by 215, we get 7 and a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 307.0
Deduct 1505 from 1516 and we're left with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 215

Moving on to step 6:
215 can be fit into 113 0 times, resulting in a remainder of 113.
Use 0 as the next digit of our solution. 
Result so far: 3070.0
Subtracting 0 from 113 leaves us with 113.
Bring next digit (7) of the dividend behind the 113 and repeat the process: 1137 / 215

Let's proceed to step 7:
If we divide 1137 by 215, we get 5 and a remainder of 62.
Use 5 as the next digit of our solution. 
Result so far: 30705.0
Deduct 1075 from 1137 and we're left with 62.
Grab the next digit (6) from the dividend, add it to 62, then carry on: 626 / 215

Step 8:
When dividing 626 by 215, we get 2 with a remainder of 196.
Write down 2 as next digit of the result. 
Result so far: 307052.0
Subtract 430 from 626 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 9:
The number 215 fits into 1960 9 times, leaving a remainder of 25.
The next digit of our result is 9. 
Result so far: 307052.9
The remainder is 25 after subtracting 1935 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
215 can be fit into 250 1 times, resulting in a remainder of 35.
The next digit of our result is 1. 
Result so far: 307052.91
Subtract 215 from 250 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
The number 215 fits into 350 1 times, leaving a remainder of 135.
Record the quotient 1 as the next digit in the result. 
Result so far: 307052.911
If we take 215 away from 350, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final outcome is 307052.911, with a leftover of 0.0135.
