We divide 39858778 by 609
We want to figure out the number of times 39858778 can be divided by 609.

Going ahead to step 1:
When dividing 3 by 609, 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.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 609

Step 2:
39 divided by 609 is 0 with 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.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 609

Advancing to step 3:
If we divide 398 by 609, we get 0 and a remainder of 398.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 398 after subtracting 0 from 398.
Bring next digit (5) of the dividend behind the 398 and repeat the process: 3985 / 609

Moving on to step 4:
609 goes into 3985 6 times with a remainder of 331.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 3654 from 3985 leaves us with 331.
Grab the next digit (8) from the dividend, add it to 331, then carry on: 3318 / 609

On to step 5:
3318 divided by 609 is 5 with a remainder of 273.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Deduct 3045 from 3318 and we're left with 273.
Include the next digit (7) from the dividend after 273, then repeat: 2737 / 609

Let's proceed to step 6:
When dividing 2737 by 609, we get 4 with a remainder of 301.
The number 4 becomes the next digit in our result. 
Result so far: 654.0
The remainder is 301 after subtracting 2436 from 2737.
Grab the next digit (7) from the dividend, add it to 301, then carry on: 3017 / 609

Advancing to step 7:
609 can be fit into 3017 4 times, resulting in a remainder of 581.
The next digit of our result is 4. 
Result so far: 6544.0
The remainder is 581 after subtracting 2436 from 3017.
Fetch the next digit (8) from the dividend, attach it to 581 and continue: 5818 / 609

Let's proceed to step 8:
609 can be fit into 5818 9 times, resulting in a remainder of 337.
The number 9 becomes the next digit in our result. 
Result so far: 65449.0
Deduct 5481 from 5818 and we're left with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Step 9:
When dividing 3370 by 609, we get 5 with a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 65449.5
Subtracting 3045 from 3370 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 10:
When dividing 3250 by 609, we get 5 with a remainder of 205.
The next digit of our result is 5. 
Result so far: 65449.55
Subtract 3045 from 3250 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

After the division, we end up with 65449.55 and a remainder of 0.205.
