Let's divide 399343 by 53
Let's see how many times 53 fits into 399343.

Step 1:
3 divided by 53 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 53

Moving on to step 2:
When dividing 39 by 53, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 53

Going ahead to step 3:
53 can be fit into 399 7 times, resulting in a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 371 from 399 and we're left with 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 53

Going ahead to step 4:
53 can be fit into 283 5 times, resulting in a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we subtract 265 from 283, we get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 53

Going ahead to step 5:
184 divided by 53 is 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 753.0
Subtract 159 from 184 to get 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 53

Advancing to step 6:
The number 53 fits into 253 4 times, leaving a remainder of 41.
The next digit of our result is 4. 
Result so far: 7534.0
The remainder is 41 after subtracting 212 from 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
If we divide 410 by 53, we get 7 and a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 7534.7
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.

Let's proceed to step 8:
53 goes into 390 7 times with a remainder of 19.
The next digit of our result is 7. 
Result so far: 7534.77
The remainder is 19 after subtracting 371 from 390.
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 7534.77, and the remainder is 0.019.
