We look at the division of 75149134 by 215 
We're looking to find how many times 215 goes into 75149134.

Step 1:
If we divide 7 by 215, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 215

On to step 2:
75 divided by 215 is 0 with a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Fetch the next digit (1) from the dividend, attach it to 75 and continue: 751 / 215

Moving on to step 3:
215 can be fit into 751 3 times, resulting in a remainder of 106.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 645 from 751 leaves us with 106.
Append the next digit (4) from the dividend to 106 and continue with: 1064 / 215

Moving on to step 4:
1064 divided by 215 is 4 with a remainder of 204.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we take 860 away from 1064, we end up with 204.
Append the next digit (9) from the dividend to 204 and continue with: 2049 / 215

Advancing to step 5:
215 can be fit into 2049 9 times, resulting in a remainder of 114.
Put 9 as the next digit of the answer. 
Result so far: 349.0
If we subtract 1935 from 2049, we get 114.
Bring next digit (1) of the dividend behind the 114 and repeat the process: 1141 / 215

Advancing to step 6:
215 goes into 1141 5 times with a remainder of 66.
Use 5 as the next digit of our solution. 
Result so far: 3495.0
Subtracting 1075 from 1141 leaves us with 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 215

On to step 7:
215 goes into 663 3 times with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 34953.0
The remainder is 18 after subtracting 645 from 663.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 215

Advancing to step 8:
215 can be fit into 184 0 times, resulting in a remainder of 184.
Record the quotient 0 as the next digit in the result. 
Result so far: 349530.0
Subtracting 0 from 184 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 9:
The number 215 fits into 1840 8 times, leaving a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 349530.8
Subtract 1720 from 1840 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
215 goes into 1200 5 times with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 349530.85
Subtract 1075 from 1200 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 11:
If we divide 1250 by 215, we get 5 and a remainder of 175.
The next digit of our result is 5. 
Result so far: 349530.855
Deduct 1075 from 1250 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The quotient of the division is 349530.855, and the remainder is 0.0175.
