557045 divided by 69 
The aim is to understand the frequency of 69 in 557045.

On to step 1:
When dividing 5 by 69, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 69

Moving on to step 2:
The number 69 fits into 55 0 times, leaving a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 69

Advancing to step 3:
557 divided by 69 is 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 552 from 557, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 69

Let's proceed to step 4:
When dividing 50 by 69, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 80.0
If we take 0 away from 50, we end up with 50.
Include the next digit (4) from the dividend after 50, then repeat: 504 / 69

Going ahead to step 5:
504 divided by 69 is 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 807.0
If we subtract 483 from 504, we get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 69

Let's proceed to step 6:
The number 69 fits into 215 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 8073.0
Deduct 207 from 215 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
The number 69 fits into 80 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 8073.1
If we subtract 69 from 80, 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.

Advancing to step 8:
When dividing 110 by 69, we get 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 8073.11
Subtract 69 from 110 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 8073.11, with a leftover of 0.041.
