39090608 ÷ 397 
We're looking to find how many times 397 goes into 39090608.

Advancing to step 1:
397 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 397

Going ahead to step 2:
397 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 397

Step 3:
397 goes into 390 0 times with a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 390, we end up with 390.
Include the next digit (9) from the dividend after 390, then repeat: 3909 / 397

Advancing to step 4:
When dividing 3909 by 397, we get 9 with a remainder of 336.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 3573 from 3909 to get 336.
Take the next digit (0) from the dividend and append it to 336, then repeat: 3360 / 397

Let's proceed to step 5:
3360 divided by 397 is 8 with a remainder of 184.
The next digit of our result is 8. 
Result so far: 98.0
The remainder is 184 after subtracting 3176 from 3360.
Fetch the next digit (6) from the dividend, attach it to 184 and continue: 1846 / 397

Moving on to step 6:
When dividing 1846 by 397, we get 4 with a remainder of 258.
Use 4 as the next digit of our solution. 
Result so far: 984.0
Deduct 1588 from 1846 and we're left with 258.
Append the next digit (0) from the dividend to 258 and continue with: 2580 / 397

Let's proceed to step 7:
When dividing 2580 by 397, we get 6 with a remainder of 198.
The number 6 becomes the next digit in our result. 
Result so far: 9846.0
If we subtract 2382 from 2580, we get 198.
Include the next digit (8) from the dividend after 198, then repeat: 1988 / 397

Let's proceed to step 8:
If we divide 1988 by 397, we get 5 and a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 98465.0
If we take 1985 away from 1988, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
397 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 98465.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
The number 397 fits into 300 0 times, leaving a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 98465.0
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 98465.0 with a remainder of 0.3.
