We look at the division of 48239778 by 397 
We're looking to find how many times 397 goes into 48239778.

Let's proceed to step 1:
The number 397 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 397

Advancing to step 2:
397 goes into 48 0 times with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 397

Advancing to step 3:
397 goes into 482 1 times with a remainder of 85.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 85 after subtracting 397 from 482.
Bring next digit (3) of the dividend behind the 85 and repeat the process: 853 / 397

Moving on to step 4:
If we divide 853 by 397, we get 2 and a remainder of 59.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 794 from 853 to get 59.
Append the next digit (9) from the dividend to 59 and continue with: 599 / 397

Let's proceed to step 5:
599 divided by 397 is 1 with a remainder of 202.
Write down 1 as next digit of the result. 
Result so far: 121.0
Subtract 397 from 599 to get 202.
Take the next digit (7) from the dividend and append it to 202, then repeat: 2027 / 397

Moving on to step 6:
When dividing 2027 by 397, we get 5 with a remainder of 42.
Put 5 as the next digit of the answer. 
Result so far: 1215.0
Deduct 1985 from 2027 and we're left with 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 397

Advancing to step 7:
397 goes into 427 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 12151.0
Subtracting 397 from 427 leaves us with 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 397

Step 8:
If we divide 308 by 397, we get 0 and a remainder of 308.
Write down 0 as next digit of the result. 
Result so far: 121510.0
Subtracting 0 from 308 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 9:
The number 397 fits into 3080 7 times, leaving a remainder of 301.
Write down 7 as next digit of the result. 
Result so far: 121510.7
If we take 2779 away from 3080, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

On to step 10:
If we divide 3010 by 397, we get 7 and a remainder of 231.
The number 7 becomes the next digit in our result. 
Result so far: 121510.77
Subtract 2779 from 3010 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

The final result is 121510.77 with a remainder of 0.231.
