378061 divided by 69 
The aim is to understand the frequency of 69 in 378061.

Moving on to step 1:
When dividing 3 by 69, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 69

Let's proceed to step 2:
If we divide 37 by 69, we get 0 and a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 69

Going ahead to step 3:
The number 69 fits into 378 5 times, leaving a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 345 away from 378, we end up with 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 69

Advancing to step 4:
The number 69 fits into 330 4 times, leaving a remainder of 54.
The next digit of our result is 4. 
Result so far: 54.0
Subtracting 276 from 330 leaves us with 54.
Grab the next digit (6) from the dividend, add it to 54, then carry on: 546 / 69

Let's proceed to step 5:
The number 69 fits into 546 7 times, leaving a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 547.0
If we subtract 483 from 546, we get 63.
Bring next digit (1) of the dividend behind the 63 and repeat the process: 631 / 69

Moving on to step 6:
69 can be fit into 631 9 times, resulting in a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 5479.0
If we subtract 621 from 631, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
69 can be fit into 100 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 5479.1
Subtracting 69 from 100 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 8:
310 divided by 69 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 5479.14
Deduct 276 from 310 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.

On to step 9:
The number 69 fits into 340 4 times, leaving a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 5479.144
Subtracting 276 from 340 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 5479.144 with a remainder of 0.0064.
