We look at the division of 397842 by 53 
Let's see how many times 53 fits into 397842.

Step 1:
When dividing 3 by 53, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 53

Going ahead to step 2:
If we divide 39 by 53, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 53

On to step 3:
The number 53 fits into 397 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 371 from 397 and we're left with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 53

Let's proceed to step 4:
268 divided by 53 is 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtract 265 from 268 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 53

Step 5:
53 goes into 34 0 times with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 750.0
The remainder is 34 after subtracting 0 from 34.
Include the next digit (2) from the dividend after 34, then repeat: 342 / 53

On to step 6:
When dividing 342 by 53, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 7506.0
If we subtract 318 from 342, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
53 goes into 240 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 7506.4
Subtract 212 from 240 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
53 can be fit into 280 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 7506.45
Subtracting 265 from 280 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
53 can be fit into 150 2 times, resulting in a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 7506.452
If we subtract 106 from 150, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
53 can be fit into 440 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 7506.4528
Deduct 424 from 440 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
53 can be fit into 160 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 7506.45283
Deduct 159 from 160 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 12:
When dividing 10 by 53, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 7506.45283
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
When dividing 100 by 53, we get 1 with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 7506.4528301
If we take 53 away from 100, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 14:
If we divide 470 by 53, we get 8 and a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 7506.45283018
Subtract 424 from 470 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 7506.45283018 with a remainder of 4.6e-08.
