We divide 390123 by 52
We want to figure out the number of times 390123 can be divided by 52.

Advancing to step 1:
If we divide 3 by 52, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 52

On to step 2:
39 divided by 52 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 52

Moving on to step 3:
When dividing 390 by 52, we get 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 364 from 390, we get 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 52

Going ahead to step 4:
52 goes into 261 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 75.0
If we subtract 260 from 261, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 52

Step 5:
52 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 750.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 52

Moving on to step 6:
If we divide 123 by 52, we get 2 and a remainder of 19.
The next digit of our result is 2. 
Result so far: 7502.0
Subtract 104 from 123 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
52 can be fit into 190 3 times, resulting in a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 7502.3
The remainder is 34 after subtracting 156 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
The number 52 fits into 340 6 times, leaving a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 7502.36
If we take 312 away from 340, we end up 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.

Let's proceed to step 9:
The number 52 fits into 280 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 7502.365
Subtract 260 from 280 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
When dividing 200 by 52, we get 3 with a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 7502.3653
If we subtract 156 from 200, 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.

Moving on to step 11:
If we divide 440 by 52, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 7502.36538
If we take 416 away from 440, we end up with 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 12:
52 goes into 240 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 7502.365384
If we subtract 208 from 240, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
If we divide 320 by 52, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 7502.3653846
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
52 goes into 80 1 times with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 7502.36538461
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.

The quotient of the division is 7502.36538461, and the remainder is 2.8e-08.
