Let's divide 403615 by 53
Let's see how many times 53 fits into 403615.

Going ahead to step 1:
53 can be fit into 4 0 times, resulting in 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 (0) from the dividend, add it to 4, then carry on: 40 / 53

Moving on to step 2:
The number 53 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 53

On to step 3:
If we divide 403 by 53, we get 7 and a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 371 from 403 and we're left with 32.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 53

Advancing to step 4:
53 goes into 326 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Subtracting 318 from 326 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 53

Step 5:
The number 53 fits into 81 1 times, leaving a remainder of 28.
The next digit of our result is 1. 
Result so far: 761.0
If we take 53 away from 81, we end up with 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 53

On to step 6:
The number 53 fits into 285 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 7615.0
Subtracting 265 from 285 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
200 divided by 53 is 3 with a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 7615.3
If we subtract 159 from 200, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 8:
53 goes into 410 7 times with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 7615.37
If we take 371 away from 410, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
If we divide 390 by 53, we get 7 and a remainder of 19.
The next digit of our result is 7. 
Result so far: 7615.377
Subtracting 371 from 390 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 7615.377, and the remainder is 0.0019.
