Let's divide 1508346 by 387
The aim is to understand the frequency of 387 in 1508346.

Let's proceed to step 1:
The number 387 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 387

Advancing to step 2:
When dividing 15 by 387, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 387

Step 3:
If we divide 150 by 387, we get 0 and a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 150, we get 150.
Fetch the next digit (8) from the dividend, attach it to 150 and continue: 1508 / 387

Moving on to step 4:
387 can be fit into 1508 3 times, resulting in a remainder of 347.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 347 after subtracting 1161 from 1508.
Fetch the next digit (3) from the dividend, attach it to 347 and continue: 3473 / 387

Going ahead to step 5:
When dividing 3473 by 387, we get 8 with a remainder of 377.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Deduct 3096 from 3473 and we're left with 377.
Fetch the next digit (4) from the dividend, attach it to 377 and continue: 3774 / 387

Advancing to step 6:
If we divide 3774 by 387, we get 9 and a remainder of 291.
Use 9 as the next digit of our solution. 
Result so far: 389.0
Subtracting 3483 from 3774 leaves us with 291.
Append the next digit (6) from the dividend to 291 and continue with: 2916 / 387

Let's proceed to step 7:
387 goes into 2916 7 times with a remainder of 207.
Use 7 as the next digit of our solution. 
Result so far: 3897.0
If we subtract 2709 from 2916, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 8:
When dividing 2070 by 387, we get 5 with a remainder of 135.
The next digit of our result is 5. 
Result so far: 3897.5
The remainder is 135 after subtracting 1935 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 9:
The number 387 fits into 1350 3 times, leaving a remainder of 189.
Record the quotient 3 as the next digit in the result. 
Result so far: 3897.53
The remainder is 189 after subtracting 1161 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 10:
387 can be fit into 1890 4 times, resulting in a remainder of 342.
The next digit of our result is 4. 
Result so far: 3897.534
Deduct 1548 from 1890 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Let's proceed to step 11:
When dividing 3420 by 387, we get 8 with a remainder of 324.
Put 8 as the next digit of the answer. 
Result so far: 3897.5348
Deduct 3096 from 3420 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 12:
The number 387 fits into 3240 8 times, leaving a remainder of 144.
Put 8 as the next digit of the answer. 
Result so far: 3897.53488
If we take 3096 away from 3240, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Our division results in 3897.53488 with a remaining 0.000144.
