Let's divide 390973 by 52
We want to figure out the number of times 390973 can be divided by 52.

On to step 1:
If we divide 3 by 52, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 52

Going ahead to step 2:
If we divide 39 by 52, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 52

Step 3:
When dividing 390 by 52, we get 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 364 from 390 and we're left with 26.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 52

On to step 4:
52 goes into 269 5 times with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtracting 260 from 269 leaves us with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 52

Let's proceed to step 5:
52 can be fit into 97 1 times, resulting in a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 751.0
If we subtract 52 from 97, we get 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 52

Advancing to step 6:
If we divide 453 by 52, we get 8 and a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 7518.0
Deduct 416 from 453 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
The number 52 fits into 370 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 7518.7
If we subtract 364 from 370, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
52 goes into 60 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 7518.71
Subtracting 52 from 60 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
52 can be fit into 80 1 times, resulting in a remainder of 28.
The next digit of our result is 1. 
Result so far: 7518.711
Subtracting 52 from 80 leaves us 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.

Our division results in 7518.711 with a remaining 0.0028.
