Let's divide 19290350 by 215
We're looking to find how many times 215 goes into 19290350.

Step 1:
When dividing 1 by 215, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 215

On to step 2:
The number 215 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 215

Going ahead to step 3:
215 can be fit into 192 0 times, resulting in a remainder of 192.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 192 and we're left with 192.
Append the next digit (9) from the dividend to 192 and continue with: 1929 / 215

Step 4:
215 goes into 1929 8 times with a remainder of 209.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 1720 from 1929 and we're left with 209.
Append the next digit (0) from the dividend to 209 and continue with: 2090 / 215

Moving on to step 5:
215 can be fit into 2090 9 times, resulting in a remainder of 155.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
The remainder is 155 after subtracting 1935 from 2090.
Grab the next digit (3) from the dividend, add it to 155, then carry on: 1553 / 215

Moving on to step 6:
When dividing 1553 by 215, we get 7 with a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 897.0
Subtract 1505 from 1553 to get 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 215

Moving on to step 7:
The number 215 fits into 485 2 times, leaving a remainder of 55.
The number 2 becomes the next digit in our result. 
Result so far: 8972.0
If we take 430 away from 485, we end up with 55.
Fetch the next digit (0) from the dividend, attach it to 55 and continue: 550 / 215

Going ahead to step 8:
The number 215 fits into 550 2 times, leaving a remainder of 120.
Write down 2 as next digit of the result. 
Result so far: 89722.0
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.

Going ahead to step 9:
The number 215 fits into 1200 5 times, leaving a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 89722.5
If we take 1075 away from 1200, we end up with 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 10:
If we divide 1250 by 215, we get 5 and a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 89722.55
If we take 1075 away from 1250, we end up 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.

Our division results in 89722.55 with a remaining 0.175.
