We're dividing 453017 by 49 
We want to figure out the number of times 453017 can be divided by 49.

Step 1:
49 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 49

Step 2:
49 goes into 45 0 times with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 49

Going ahead to step 3:
The number 49 fits into 453 9 times, leaving a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 441 from 453, we get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 49

Going ahead to step 4:
If we divide 120 by 49, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
Subtracting 98 from 120 leaves us with 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 49

On to step 5:
221 divided by 49 is 4 with a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 924.0
The remainder is 25 after subtracting 196 from 221.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 49

Step 6:
49 can be fit into 257 5 times, resulting in a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 9245.0
Deduct 245 from 257 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
If we divide 120 by 49, we get 2 and a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 9245.2
The remainder is 22 after subtracting 98 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
220 divided by 49 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 9245.24
The remainder is 24 after subtracting 196 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
49 goes into 240 4 times with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 9245.244
If we take 196 away from 240, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 9245.244, with a leftover of 0.0044.
