15311607 ÷ 329 
The aim is to understand the frequency of 329 in 15311607.

Advancing to step 1:
If we divide 1 by 329, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 329

Let's proceed to step 2:
15 divided by 329 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 329

Step 3:
When dividing 153 by 329, we get 0 with a remainder of 153.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 153 and we're left with 153.
Append the next digit (1) from the dividend to 153 and continue with: 1531 / 329

Let's proceed to step 4:
329 can be fit into 1531 4 times, resulting in a remainder of 215.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 1316 away from 1531, we end up with 215.
Bring next digit (1) of the dividend behind the 215 and repeat the process: 2151 / 329

Going ahead to step 5:
The number 329 fits into 2151 6 times, leaving a remainder of 177.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Subtracting 1974 from 2151 leaves us with 177.
Fetch the next digit (6) from the dividend, attach it to 177 and continue: 1776 / 329

Moving on to step 6:
When dividing 1776 by 329, we get 5 with a remainder of 131.
Put 5 as the next digit of the answer. 
Result so far: 465.0
Deduct 1645 from 1776 and we're left with 131.
Append the next digit (0) from the dividend to 131 and continue with: 1310 / 329

Step 7:
329 can be fit into 1310 3 times, resulting in a remainder of 323.
Write down 3 as next digit of the result. 
Result so far: 4653.0
Subtracting 987 from 1310 leaves us with 323.
Grab the next digit (7) from the dividend, add it to 323, then carry on: 3237 / 329

Let's proceed to step 8:
The number 329 fits into 3237 9 times, leaving a remainder of 276.
Put 9 as the next digit of the answer. 
Result so far: 46539.0
Subtracting 2961 from 3237 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 9:
329 goes into 2760 8 times with a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 46539.8
The remainder is 128 after subtracting 2632 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 10:
If we divide 1280 by 329, we get 3 and a remainder of 293.
Use 3 as the next digit of our solution. 
Result so far: 46539.83
Subtract 987 from 1280 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Going ahead to step 11:
2930 divided by 329 is 8 with a remainder of 298.
Put 8 as the next digit of the answer. 
Result so far: 46539.838
If we take 2632 away from 2930, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 12:
329 can be fit into 2980 9 times, resulting in a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 46539.8389
If we subtract 2961 from 2980, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
If we divide 190 by 329, we get 0 and a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 46539.8389
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 14:
When dividing 1900 by 329, we get 5 with a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 46539.838905
If we subtract 1645 from 1900, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 15:
329 goes into 2550 7 times with a remainder of 247.
Use 7 as the next digit of our solution. 
Result so far: 46539.8389057
Subtracting 2303 from 2550 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Going ahead to step 16:
If we divide 2470 by 329, we get 7 and a remainder of 167.
Put 7 as the next digit of the answer. 
Result so far: 46539.83890577
The remainder is 167 after subtracting 2303 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

In conclusion, the division gives 46539.83890577 with a balance of 1.67e-07.
