We look at the division of 77858542 by 329 
The aim is to understand the frequency of 329 in 77858542.

Moving on to step 1:
If we divide 7 by 329, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 329

On to step 2:
When dividing 77 by 329, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 329

Going ahead to step 3:
329 goes into 778 2 times with a remainder of 120.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 120 after subtracting 658 from 778.
Grab the next digit (5) from the dividend, add it to 120, then carry on: 1205 / 329

Step 4:
The number 329 fits into 1205 3 times, leaving a remainder of 218.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 987 from 1205, we get 218.
Fetch the next digit (8) from the dividend, attach it to 218 and continue: 2188 / 329

Advancing to step 5:
2188 divided by 329 is 6 with a remainder of 214.
The next digit of our result is 6. 
Result so far: 236.0
Deduct 1974 from 2188 and we're left with 214.
Grab the next digit (5) from the dividend, add it to 214, then carry on: 2145 / 329

Going ahead to step 6:
329 can be fit into 2145 6 times, resulting in a remainder of 171.
Use 6 as the next digit of our solution. 
Result so far: 2366.0
If we take 1974 away from 2145, we end up with 171.
Bring next digit (4) of the dividend behind the 171 and repeat the process: 1714 / 329

Going ahead to step 7:
If we divide 1714 by 329, we get 5 and a remainder of 69.
The number 5 becomes the next digit in our result. 
Result so far: 23665.0
If we take 1645 away from 1714, we end up with 69.
Append the next digit (2) from the dividend to 69 and continue with: 692 / 329

Going ahead to step 8:
329 can be fit into 692 2 times, resulting in a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 236652.0
Deduct 658 from 692 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
329 can be fit into 340 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 236652.1
If we subtract 329 from 340, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
When dividing 110 by 329, we get 0 with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 236652.1
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 11:
The number 329 fits into 1100 3 times, leaving a remainder of 113.
Record the quotient 3 as the next digit in the result. 
Result so far: 236652.103
The remainder is 113 after subtracting 987 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 12:
329 can be fit into 1130 3 times, resulting in a remainder of 143.
Record the quotient 3 as the next digit in the result. 
Result so far: 236652.1033
Subtracting 987 from 1130 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

The final result is 236652.1033 with a remainder of 0.00143.
