Let's divide 391398 by 53
We're looking to find how many times 53 goes into 391398.

Advancing to 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

Advancing 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 take 0 away from 39, we end up with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 53

Let's proceed to step 3:
391 divided by 53 is 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 20 after subtracting 371 from 391.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 53

Advancing to step 4:
The number 53 fits into 203 3 times, leaving a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we subtract 159 from 203, we get 44.
Bring next digit (9) of the dividend behind the 44 and repeat the process: 449 / 53

Advancing to step 5:
The number 53 fits into 449 8 times, leaving a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 738.0
The remainder is 25 after subtracting 424 from 449.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 53

Let's proceed to step 6:
The number 53 fits into 258 4 times, leaving a remainder of 46.
The next digit of our result is 4. 
Result so far: 7384.0
If we take 212 away from 258, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
The number 53 fits into 460 8 times, leaving a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 7384.8
Subtract 424 from 460 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
When dividing 360 by 53, we get 6 with a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 7384.86
Deduct 318 from 360 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
If we divide 420 by 53, we get 7 and a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 7384.867
Subtract 371 from 420 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 10:
490 divided by 53 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 7384.8679
The remainder is 13 after subtracting 477 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
If we divide 130 by 53, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 7384.86792
The remainder is 24 after subtracting 106 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
53 can be fit into 240 4 times, resulting in a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 7384.867924
Deduct 212 from 240 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
53 can be fit into 280 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 7384.8679245
If we take 265 away from 280, we end up 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.

Advancing to step 14:
If we divide 150 by 53, we get 2 and a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 7384.86792452
If we take 106 away from 150, 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 7384.86792452, with a leftover of 4.4e-08.
