231990 divided by 48 
We're looking to find how many times 48 goes into 231990.

Going ahead to step 1:
2 divided by 48 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 48

Let's proceed to step 2:
48 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 48

Moving on to step 3:
48 can be fit into 231 4 times, resulting in a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 192 from 231 leaves us with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 48

Going ahead to step 4:
The number 48 fits into 399 8 times, leaving a remainder of 15.
The next digit of our result is 8. 
Result so far: 48.0
Subtracting 384 from 399 leaves us with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 48

Let's proceed to step 5:
48 goes into 159 3 times with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 483.0
The remainder is 15 after subtracting 144 from 159.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 48

Let's proceed to step 6:
48 goes into 150 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 4833.0
Subtracting 144 from 150 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
48 goes into 60 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 4833.1
If we subtract 48 from 60, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
If we divide 120 by 48, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 4833.12
Subtracting 96 from 120 leaves us 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.

Going ahead to step 9:
If we divide 240 by 48, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4833.125
If we take 240 away from 240, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 48, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 4833.125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
If we divide 0 by 48, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4833.125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 4833.125 and a remainder of 0.0.
