78084625 ÷ 342 
The aim is to understand the frequency of 342 in 78084625.

Let's proceed to step 1:
If we divide 7 by 342, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 342

Step 2:
342 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 342

Moving on to step 3:
342 goes into 780 2 times with a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 684 from 780 to get 96.
Append the next digit (8) from the dividend to 96 and continue with: 968 / 342

On to step 4:
The number 342 fits into 968 2 times, leaving a remainder of 284.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 684 from 968 and we're left with 284.
Take the next digit (4) from the dividend and append it to 284, then repeat: 2844 / 342

On to step 5:
If we divide 2844 by 342, we get 8 and a remainder of 108.
Use 8 as the next digit of our solution. 
Result so far: 228.0
Subtracting 2736 from 2844 leaves us with 108.
Fetch the next digit (6) from the dividend, attach it to 108 and continue: 1086 / 342

Moving on to step 6:
342 can be fit into 1086 3 times, resulting in a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 2283.0
The remainder is 60 after subtracting 1026 from 1086.
Append the next digit (2) from the dividend to 60 and continue with: 602 / 342

Step 7:
When dividing 602 by 342, we get 1 with a remainder of 260.
The number 1 becomes the next digit in our result. 
Result so far: 22831.0
Subtracting 342 from 602 leaves us with 260.
Bring next digit (5) of the dividend behind the 260 and repeat the process: 2605 / 342

Moving on to step 8:
342 goes into 2605 7 times with a remainder of 211.
Put 7 as the next digit of the answer. 
Result so far: 228317.0
The remainder is 211 after subtracting 2394 from 2605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Advancing to step 9:
The number 342 fits into 2110 6 times, leaving a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 228317.6
If we take 2052 away from 2110, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
When dividing 580 by 342, we get 1 with a remainder of 238.
Put 1 as the next digit of the answer. 
Result so far: 228317.61
Subtract 342 from 580 to 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 11:
342 can be fit into 2380 6 times, resulting in a remainder of 328.
Put 6 as the next digit of the answer. 
Result so far: 228317.616
Subtract 2052 from 2380 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 12:
3280 divided by 342 is 9 with a remainder of 202.
Record the quotient 9 as the next digit in the result. 
Result so far: 228317.6169
If we subtract 3078 from 3280, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 13:
342 can be fit into 2020 5 times, resulting in a remainder of 310.
The number 5 becomes the next digit in our result. 
Result so far: 228317.61695
Subtract 1710 from 2020 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 14:
342 can be fit into 3100 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 228317.616959
If we take 3078 away from 3100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 15:
342 goes into 220 0 times with a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 228317.616959
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 16:
342 goes into 2200 6 times with a remainder of 148.
Put 6 as the next digit of the answer. 
Result so far: 228317.61695906
If we take 2052 away from 2200, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

After the division, we end up with 228317.61695906 and a remainder of 1.48e-07.
