14863007 ÷ 591 
The aim is to understand the frequency of 591 in 14863007.

Going ahead to step 1:
If we divide 1 by 591, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 591

Step 2:
If we divide 14 by 591, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 591

Step 3:
The number 591 fits into 148 0 times, leaving a remainder of 148.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 148 after subtracting 0 from 148.
Bring next digit (6) of the dividend behind the 148 and repeat the process: 1486 / 591

Advancing to step 4:
591 goes into 1486 2 times with a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1182 from 1486 to get 304.
Include the next digit (3) from the dividend after 304, then repeat: 3043 / 591

Step 5:
591 can be fit into 3043 5 times, resulting in a remainder of 88.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 2955 from 3043 leaves us with 88.
Take the next digit (0) from the dividend and append it to 88, then repeat: 880 / 591

Step 6:
591 can be fit into 880 1 times, resulting in a remainder of 289.
Put 1 as the next digit of the answer. 
Result so far: 251.0
The remainder is 289 after subtracting 591 from 880.
Fetch the next digit (0) from the dividend, attach it to 289 and continue: 2890 / 591

Advancing to step 7:
If we divide 2890 by 591, we get 4 and a remainder of 526.
The number 4 becomes the next digit in our result. 
Result so far: 2514.0
Subtracting 2364 from 2890 leaves us with 526.
Include the next digit (7) from the dividend after 526, then repeat: 5267 / 591

Moving on to step 8:
The number 591 fits into 5267 8 times, leaving a remainder of 539.
Use 8 as the next digit of our solution. 
Result so far: 25148.0
If we subtract 4728 from 5267, we get 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Step 9:
When dividing 5390 by 591, we get 9 with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 25148.9
If we take 5319 away from 5390, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 10:
If we divide 710 by 591, we get 1 and a remainder of 119.
The number 1 becomes the next digit in our result. 
Result so far: 25148.91
The remainder is 119 after subtracting 591 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 11:
591 goes into 1190 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 25148.912
If we take 1182 away from 1190, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
80 divided by 591 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 25148.912
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
When dividing 800 by 591, we get 1 with a remainder of 209.
The number 1 becomes the next digit in our result. 
Result so far: 25148.91201
If we take 591 away from 800, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Moving on to step 14:
591 goes into 2090 3 times with a remainder of 317.
The next digit of our result is 3. 
Result so far: 25148.912013
Subtract 1773 from 2090 to get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Going ahead to step 15:
If we divide 3170 by 591, we get 5 and a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 25148.9120135
Deduct 2955 from 3170 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 16:
If we divide 2150 by 591, we get 3 and a remainder of 377.
The next digit of our result is 3. 
Result so far: 25148.91201353
Subtracting 1773 from 2150 leaves us with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

After the division, we end up with 25148.91201353 and a remainder of 3.77e-07.
