We're dividing 55235649 by 345 
The aim is to understand the frequency of 345 in 55235649.

Going ahead to step 1:
5 divided by 345 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 345

Advancing to step 2:
If we divide 55 by 345, we get 0 and 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 (2) of the dividend behind the 55 and repeat the process: 552 / 345

Step 3:
345 can be fit into 552 1 times, resulting in a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 345 from 552 and we're left with 207.
Fetch the next digit (3) from the dividend, attach it to 207 and continue: 2073 / 345

Step 4:
If we divide 2073 by 345, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 3 after subtracting 2070 from 2073.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 345

On to step 5:
When dividing 35 by 345, we get 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 160.0
If we subtract 0 from 35, we get 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 345

Going ahead to step 6:
If we divide 356 by 345, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1601.0
If we subtract 345 from 356, we get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 345

On to step 7:
If we divide 114 by 345, we get 0 and a remainder of 114.
Put 0 as the next digit of the answer. 
Result so far: 16010.0
If we take 0 away from 114, we end up with 114.
Grab the next digit (9) from the dividend, add it to 114, then carry on: 1149 / 345

On to step 8:
345 goes into 1149 3 times with a remainder of 114.
Write down 3 as next digit of the result. 
Result so far: 160103.0
Deduct 1035 from 1149 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.

On to step 9:
345 can be fit into 1140 3 times, resulting in a remainder of 105.
Use 3 as the next digit of our solution. 
Result so far: 160103.3
Subtract 1035 from 1140 to get 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:
If we divide 1050 by 345, we get 3 and a remainder of 15.
The next digit of our result is 3. 
Result so far: 160103.33
Deduct 1035 from 1050 and we're left 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.

In conclusion, the division gives 160103.33 with a balance of 0.015.
