We look at the division of 390790 by 74 
We want to figure out the number of times 390790 can be divided by 74.

Advancing to step 1:
If we divide 3 by 74, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our 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 / 74

On to step 2:
39 divided by 74 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.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 74

On to step 3:
390 divided by 74 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 20 after subtracting 370 from 390.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 74

Going ahead to step 4:
207 divided by 74 is 2 with a remainder of 59.
The next digit of our result is 2. 
Result so far: 52.0
The remainder is 59 after subtracting 148 from 207.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 74

On to step 5:
74 goes into 599 8 times with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 528.0
Subtracting 592 from 599 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 74

Going ahead to step 6:
74 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 5280.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 7:
The number 74 fits into 700 9 times, leaving a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 5280.9
If we take 666 away from 700, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
The number 74 fits into 340 4 times, leaving a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 5280.94
The remainder is 44 after subtracting 296 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
When dividing 440 by 74, we get 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 5280.945
Subtracting 370 from 440 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
700 divided by 74 is 9 with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 5280.9459
Deduct 666 from 700 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
The number 74 fits into 340 4 times, leaving a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 5280.94594
If we take 296 away from 340, 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.

Let's proceed to step 12:
74 can be fit into 440 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 5280.945945
The remainder is 70 after subtracting 370 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 13:
The number 74 fits into 700 9 times, leaving a remainder of 34.
The next digit of our result is 9. 
Result so far: 5280.9459459
The remainder is 34 after subtracting 666 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 14:
340 divided by 74 is 4 with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 5280.94594594
Subtract 296 from 340 to 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.

The final result is 5280.94594594 with a remainder of 4.4e-08.
