We're dividing 615148 by 45 
We want to figure out the number of times 615148 can be divided by 45.

Let's proceed to step 1:
6 divided by 45 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 45

Advancing to step 2:
45 can be fit into 61 1 times, resulting in a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 45 from 61 leaves us with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 45

Going ahead to step 3:
The number 45 fits into 165 3 times, leaving a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 135 from 165 and we're left with 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 45

Moving on to step 4:
45 goes into 301 6 times with a remainder of 31.
The next digit of our result is 6. 
Result so far: 136.0
Deduct 270 from 301 and we're left with 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 45

On to step 5:
If we divide 314 by 45, we get 6 and a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 1366.0
Subtract 270 from 314 to get 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 45

Step 6:
If we divide 448 by 45, we get 9 and a remainder of 43.
The next digit of our result is 9. 
Result so far: 13669.0
The remainder is 43 after subtracting 405 from 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
If we divide 430 by 45, we get 9 and a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 13669.9
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
When dividing 250 by 45, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 13669.95
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 13669.955
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 13669.955, and the remainder is 0.0025.
