30587287 ÷ 387 
The aim is to understand the frequency of 387 in 30587287.

Advancing to step 1:
When dividing 3 by 387, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 387

Let's proceed to step 2:
387 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 387

Advancing to step 3:
305 divided by 387 is 0 with a remainder of 305.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 305 to get 305.
Take the next digit (8) from the dividend and append it to 305, then repeat: 3058 / 387

Moving on to step 4:
If we divide 3058 by 387, we get 7 and a remainder of 349.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 2709 from 3058, we get 349.
Take the next digit (7) from the dividend and append it to 349, then repeat: 3497 / 387

On to step 5:
387 can be fit into 3497 9 times, resulting in a remainder of 14.
The next digit of our result is 9. 
Result so far: 79.0
If we take 3483 away from 3497, we end up with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 387

Moving on to step 6:
When dividing 142 by 387, we get 0 with a remainder of 142.
The next digit of our result is 0. 
Result so far: 790.0
If we take 0 away from 142, we end up with 142.
Include the next digit (8) from the dividend after 142, then repeat: 1428 / 387

Step 7:
387 can be fit into 1428 3 times, resulting in a remainder of 267.
Put 3 as the next digit of the answer. 
Result so far: 7903.0
Subtract 1161 from 1428 to get 267.
Grab the next digit (7) from the dividend, add it to 267, then carry on: 2677 / 387

Step 8:
If we divide 2677 by 387, we get 6 and a remainder of 355.
Use 6 as the next digit of our solution. 
Result so far: 79036.0
The remainder is 355 after subtracting 2322 from 2677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 9:
When dividing 3550 by 387, we get 9 with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 79036.9
If we take 3483 away from 3550, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 10:
The number 387 fits into 670 1 times, leaving a remainder of 283.
Put 1 as the next digit of the answer. 
Result so far: 79036.91
Deduct 387 from 670 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Step 11:
387 can be fit into 2830 7 times, resulting in a remainder of 121.
The next digit of our result is 7. 
Result so far: 79036.917
The remainder is 121 after subtracting 2709 from 2830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 12:
387 goes into 1210 3 times with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 79036.9173
Subtracting 1161 from 1210 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 13:
490 divided by 387 is 1 with a remainder of 103.
Record the quotient 1 as the next digit in the result. 
Result so far: 79036.91731
If we subtract 387 from 490, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 14:
The number 387 fits into 1030 2 times, leaving a remainder of 256.
Use 2 as the next digit of our solution. 
Result so far: 79036.917312
Subtracting 774 from 1030 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 15:
The number 387 fits into 2560 6 times, leaving a remainder of 238.
Put 6 as the next digit of the answer. 
Result so far: 79036.9173126
If we subtract 2322 from 2560, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 16:
When dividing 2380 by 387, we get 6 with a remainder of 58.
The next digit of our result is 6. 
Result so far: 79036.91731266
The remainder is 58 after subtracting 2322 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 79036.91731266 with a remaining 5.8e-08.
