We look at the division of 22159239 by 345 
The aim is to understand the frequency of 345 in 22159239.

Advancing to step 1:
345 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 345

On to step 2:
345 goes into 22 0 times with a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 345

On to step 3:
When dividing 221 by 345, we get 0 with a remainder of 221.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 221 after subtracting 0 from 221.
Append the next digit (5) from the dividend to 221 and continue with: 2215 / 345

Step 4:
345 can be fit into 2215 6 times, resulting in a remainder of 145.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 2070 from 2215 leaves us with 145.
Bring next digit (9) of the dividend behind the 145 and repeat the process: 1459 / 345

Advancing to step 5:
345 can be fit into 1459 4 times, resulting in a remainder of 79.
The next digit of our result is 4. 
Result so far: 64.0
Subtract 1380 from 1459 to get 79.
Append the next digit (2) from the dividend to 79 and continue with: 792 / 345

Going ahead to step 6:
The number 345 fits into 792 2 times, leaving a remainder of 102.
Use 2 as the next digit of our solution. 
Result so far: 642.0
Subtracting 690 from 792 leaves us with 102.
Grab the next digit (3) from the dividend, add it to 102, then carry on: 1023 / 345

Moving on to step 7:
If we divide 1023 by 345, we get 2 and a remainder of 333.
The number 2 becomes the next digit in our result. 
Result so far: 6422.0
Subtracting 690 from 1023 leaves us with 333.
Fetch the next digit (9) from the dividend, attach it to 333 and continue: 3339 / 345

Moving on to step 8:
If we divide 3339 by 345, we get 9 and a remainder of 234.
Write down 9 as next digit of the result. 
Result so far: 64229.0
Deduct 3105 from 3339 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 9:
The number 345 fits into 2340 6 times, leaving a remainder of 270.
Write down 6 as next digit of the result. 
Result so far: 64229.6
If we subtract 2070 from 2340, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 10:
The number 345 fits into 2700 7 times, leaving a remainder of 285.
The number 7 becomes the next digit in our result. 
Result so far: 64229.67
The remainder is 285 after subtracting 2415 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 11:
The number 345 fits into 2850 8 times, leaving a remainder of 90.
The number 8 becomes the next digit in our result. 
Result so far: 64229.678
Subtract 2760 from 2850 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
900 divided by 345 is 2 with a remainder of 210.
Record the quotient 2 as the next digit in the result. 
Result so far: 64229.6782
Subtract 690 from 900 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 13:
2100 divided by 345 is 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 64229.67826
The remainder is 30 after subtracting 2070 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
The number 345 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 64229.67826
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 15:
3000 divided by 345 is 8 with a remainder of 240.
Put 8 as the next digit of the answer. 
Result so far: 64229.6782608
Subtracting 2760 from 3000 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 16:
2400 divided by 345 is 6 with a remainder of 330.
The next digit of our result is 6. 
Result so far: 64229.67826086
Subtracting 2070 from 2400 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The final result is 64229.67826086 with a remainder of 3.3e-07.
