We're dividing 69442879 by 678 
The aim is to understand the frequency of 678 in 69442879.

Step 1:
The number 678 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 678

Going ahead to step 2:
69 divided by 678 is 0 with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Bring next digit (4) of the dividend behind the 69 and repeat the process: 694 / 678

Moving on to step 3:
The number 678 fits into 694 1 times, leaving a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 678 from 694 leaves us with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 678

Moving on to step 4:
The number 678 fits into 164 0 times, leaving a remainder of 164.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 164 and we're left with 164.
Fetch the next digit (2) from the dividend, attach it to 164 and continue: 1642 / 678

On to step 5:
1642 divided by 678 is 2 with a remainder of 286.
Use 2 as the next digit of our solution. 
Result so far: 102.0
The remainder is 286 after subtracting 1356 from 1642.
Fetch the next digit (8) from the dividend, attach it to 286 and continue: 2868 / 678

Step 6:
678 can be fit into 2868 4 times, resulting in a remainder of 156.
Write down 4 as next digit of the result. 
Result so far: 1024.0
Subtracting 2712 from 2868 leaves us with 156.
Take the next digit (7) from the dividend and append it to 156, then repeat: 1567 / 678

On to step 7:
1567 divided by 678 is 2 with a remainder of 211.
Use 2 as the next digit of our solution. 
Result so far: 10242.0
Deduct 1356 from 1567 and we're left with 211.
Include the next digit (9) from the dividend after 211, then repeat: 2119 / 678

Going ahead to step 8:
If we divide 2119 by 678, we get 3 and a remainder of 85.
Write down 3 as next digit of the result. 
Result so far: 102423.0
If we take 2034 away from 2119, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 9:
When dividing 850 by 678, we get 1 with a remainder of 172.
The number 1 becomes the next digit in our result. 
Result so far: 102423.1
Subtracting 678 from 850 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 10:
678 goes into 1720 2 times with a remainder of 364.
Use 2 as the next digit of our solution. 
Result so far: 102423.12
If we take 1356 away from 1720, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 11:
If we divide 3640 by 678, we get 5 and a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 102423.125
Subtract 3390 from 3640 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 12:
If we divide 2500 by 678, we get 3 and a remainder of 466.
Put 3 as the next digit of the answer. 
Result so far: 102423.1253
If we subtract 2034 from 2500, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 13:
678 goes into 4660 6 times with a remainder of 592.
Record the quotient 6 as the next digit in the result. 
Result so far: 102423.12536
Deduct 4068 from 4660 and we're left with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Going ahead to step 14:
5920 divided by 678 is 8 with a remainder of 496.
The next digit of our result is 8. 
Result so far: 102423.125368
If we take 5424 away from 5920, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 15:
The number 678 fits into 4960 7 times, leaving a remainder of 214.
Put 7 as the next digit of the answer. 
Result so far: 102423.1253687
If we subtract 4746 from 4960, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 16:
When dividing 2140 by 678, we get 3 with a remainder of 106.
Use 3 as the next digit of our solution. 
Result so far: 102423.12536873
If we take 2034 away from 2140, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The final result is 102423.12536873 with a remainder of 1.06e-07.
