We look at the division of 42869950 by 215 
Our goal is to divide 42869950 by 215.

On to step 1:
When dividing 4 by 215, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 215

Advancing to step 2:
The number 215 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 215

Moving on to step 3:
215 goes into 428 1 times with a remainder of 213.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 215 from 428, we get 213.
Bring next digit (6) of the dividend behind the 213 and repeat the process: 2136 / 215

Advancing to step 4:
If we divide 2136 by 215, we get 9 and a remainder of 201.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 1935 from 2136 to get 201.
Take the next digit (9) from the dividend and append it to 201, then repeat: 2019 / 215

On to step 5:
215 goes into 2019 9 times with a remainder of 84.
Write down 9 as next digit of the result. 
Result so far: 199.0
If we subtract 1935 from 2019, we get 84.
Grab the next digit (9) from the dividend, add it to 84, then carry on: 849 / 215

Moving on to step 6:
The number 215 fits into 849 3 times, leaving a remainder of 204.
The next digit of our result is 3. 
Result so far: 1993.0
The remainder is 204 after subtracting 645 from 849.
Bring next digit (5) of the dividend behind the 204 and repeat the process: 2045 / 215

Going ahead to step 7:
The number 215 fits into 2045 9 times, leaving a remainder of 110.
Write down 9 as next digit of the result. 
Result so far: 19939.0
Subtract 1935 from 2045 to get 110.
Include the next digit (0) from the dividend after 110, then repeat: 1100 / 215

Advancing to step 8:
If we divide 1100 by 215, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 199395.0
Subtract 1075 from 1100 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
The number 215 fits into 250 1 times, leaving a remainder of 35.
The next digit of our result is 1. 
Result so far: 199395.1
Deduct 215 from 250 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 10:
215 goes into 350 1 times with a remainder of 135.
Put 1 as the next digit of the answer. 
Result so far: 199395.11
The remainder is 135 after subtracting 215 from 350.
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 result is 199395.11 with a remainder of 0.135.
