We're dividing 69930579 by 345 
The aim is to understand the frequency of 345 in 69930579.

Moving on to step 1:
If we divide 6 by 345, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 345

Let's proceed to step 2:
If we divide 69 by 345, we get 0 and a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Include the next digit (9) from the dividend after 69, then repeat: 699 / 345

Let's proceed to step 3:
If we divide 699 by 345, we get 2 and a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 690 from 699 and we're left with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 345

Step 4:
The number 345 fits into 93 0 times, leaving a remainder of 93.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 93 leaves us with 93.
Bring next digit (0) of the dividend behind the 93 and repeat the process: 930 / 345

Step 5:
If we divide 930 by 345, we get 2 and a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 202.0
If we subtract 690 from 930, we get 240.
Append the next digit (5) from the dividend to 240 and continue with: 2405 / 345

On to step 6:
2405 divided by 345 is 6 with a remainder of 335.
Record the quotient 6 as the next digit in the result. 
Result so far: 2026.0
If we subtract 2070 from 2405, we get 335.
Take the next digit (7) from the dividend and append it to 335, then repeat: 3357 / 345

Advancing to step 7:
345 can be fit into 3357 9 times, resulting in a remainder of 252.
Record the quotient 9 as the next digit in the result. 
Result so far: 20269.0
Subtract 3105 from 3357 to get 252.
Grab the next digit (9) from the dividend, add it to 252, then carry on: 2529 / 345

Going ahead to step 8:
345 goes into 2529 7 times with a remainder of 114.
Put 7 as the next digit of the answer. 
Result so far: 202697.0
Deduct 2415 from 2529 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 9:
When dividing 1140 by 345, we get 3 with a remainder of 105.
Use 3 as the next digit of our solution. 
Result so far: 202697.3
Subtracting 1035 from 1140 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 10:
345 can be fit into 1050 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 202697.33
Subtracting 1035 from 1050 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 202697.33, with a leftover of 0.015.
