53983484 ÷ 329 
The aim is to understand the frequency of 329 in 53983484.

Step 1:
329 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 329

Advancing to step 2:
329 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 329

Step 3:
When dividing 539 by 329, we get 1 with a remainder of 210.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 329 from 539 and we're left with 210.
Fetch the next digit (8) from the dividend, attach it to 210 and continue: 2108 / 329

On to step 4:
2108 divided by 329 is 6 with a remainder of 134.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 1974 from 2108 to get 134.
Include the next digit (3) from the dividend after 134, then repeat: 1343 / 329

Moving on to step 5:
The number 329 fits into 1343 4 times, leaving a remainder of 27.
The next digit of our result is 4. 
Result so far: 164.0
Deduct 1316 from 1343 and we're left with 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 329

Moving on to step 6:
329 goes into 274 0 times with a remainder of 274.
The number 0 becomes the next digit in our result. 
Result so far: 1640.0
Subtract 0 from 274 to get 274.
Append the next digit (8) from the dividend to 274 and continue with: 2748 / 329

Going ahead to step 7:
The number 329 fits into 2748 8 times, leaving a remainder of 116.
The next digit of our result is 8. 
Result so far: 16408.0
If we take 2632 away from 2748, we end up with 116.
Take the next digit (4) from the dividend and append it to 116, then repeat: 1164 / 329

Advancing to step 8:
If we divide 1164 by 329, we get 3 and a remainder of 177.
Write down 3 as next digit of the result. 
Result so far: 164083.0
The remainder is 177 after subtracting 987 from 1164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 9:
329 can be fit into 1770 5 times, resulting in a remainder of 125.
The next digit of our result is 5. 
Result so far: 164083.5
Subtracting 1645 from 1770 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 10:
The number 329 fits into 1250 3 times, leaving a remainder of 263.
Write down 3 as next digit of the result. 
Result so far: 164083.53
If we subtract 987 from 1250, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Moving on to step 11:
If we divide 2630 by 329, we get 7 and a remainder of 327.
Record the quotient 7 as the next digit in the result. 
Result so far: 164083.537
Deduct 2303 from 2630 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 12:
329 can be fit into 3270 9 times, resulting in a remainder of 309.
The next digit of our result is 9. 
Result so far: 164083.5379
Subtract 2961 from 3270 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 13:
The number 329 fits into 3090 9 times, leaving a remainder of 129.
Use 9 as the next digit of our solution. 
Result so far: 164083.53799
The remainder is 129 after subtracting 2961 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

The final result is 164083.53799 with a remainder of 0.000129.
