We divide 12148128 by 387
Our goal is to divide 12148128 by 387.

Going ahead to step 1:
If we divide 1 by 387, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 387

On to step 2:
387 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 387

Step 3:
387 goes into 121 0 times with a remainder of 121.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 121, we get 121.
Append the next digit (4) from the dividend to 121 and continue with: 1214 / 387

Step 4:
387 can be fit into 1214 3 times, resulting in a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 1161 from 1214 leaves us with 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 387

Step 5:
538 divided by 387 is 1 with a remainder of 151.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Deduct 387 from 538 and we're left with 151.
Fetch the next digit (1) from the dividend, attach it to 151 and continue: 1511 / 387

On to step 6:
The number 387 fits into 1511 3 times, leaving a remainder of 350.
Put 3 as the next digit of the answer. 
Result so far: 313.0
If we subtract 1161 from 1511, we get 350.
Bring next digit (2) of the dividend behind the 350 and repeat the process: 3502 / 387

Going ahead to step 7:
387 can be fit into 3502 9 times, resulting in a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 3139.0
Subtracting 3483 from 3502 leaves us with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 387

On to step 8:
The number 387 fits into 198 0 times, leaving a remainder of 198.
The number 0 becomes the next digit in our result. 
Result so far: 31390.0
If we take 0 away from 198, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 9:
If we divide 1980 by 387, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 31390.5
Subtract 1935 from 1980 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
387 goes into 450 1 times with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 31390.51
If we take 387 away from 450, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 11:
If we divide 630 by 387, we get 1 and a remainder of 243.
Write down 1 as next digit of the result. 
Result so far: 31390.511
Subtracting 387 from 630 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

After the division, we end up with 31390.511 and a remainder of 0.0243.
