We're dividing 55257848 by 345 
The aim is to understand the frequency of 345 in 55257848.

Step 1:
345 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 345

On to step 2:
345 goes into 55 0 times with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 345

Let's proceed to step 3:
The number 345 fits into 552 1 times, leaving a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 207 after subtracting 345 from 552.
Fetch the next digit (5) from the dividend, attach it to 207 and continue: 2075 / 345

Moving on to step 4:
345 goes into 2075 6 times with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 2070 from 2075, we get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 345

Going ahead to step 5:
The number 345 fits into 57 0 times, leaving a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
Subtract 0 from 57 to get 57.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 345

On to step 6:
345 can be fit into 578 1 times, resulting in a remainder of 233.
The next digit of our result is 1. 
Result so far: 1601.0
The remainder is 233 after subtracting 345 from 578.
Take the next digit (4) from the dividend and append it to 233, then repeat: 2334 / 345

On to step 7:
If we divide 2334 by 345, we get 6 and a remainder of 264.
Put 6 as the next digit of the answer. 
Result so far: 16016.0
The remainder is 264 after subtracting 2070 from 2334.
Grab the next digit (8) from the dividend, add it to 264, then carry on: 2648 / 345

On to step 8:
When dividing 2648 by 345, we get 7 with a remainder of 233.
The number 7 becomes the next digit in our result. 
Result so far: 160167.0
Subtract 2415 from 2648 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Moving on to step 9:
345 can be fit into 2330 6 times, resulting in a remainder of 260.
Record the quotient 6 as the next digit in the result. 
Result so far: 160167.6
If we take 2070 away from 2330, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 10:
2600 divided by 345 is 7 with a remainder of 185.
Use 7 as the next digit of our solution. 
Result so far: 160167.67
The remainder is 185 after subtracting 2415 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 11:
When dividing 1850 by 345, we get 5 with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 160167.675
Subtract 1725 from 1850 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 12:
345 goes into 1250 3 times with a remainder of 215.
The next digit of our result is 3. 
Result so far: 160167.6753
If we subtract 1035 from 1250, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 13:
When dividing 2150 by 345, we get 6 with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 160167.67536
Subtracting 2070 from 2150 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
When dividing 800 by 345, we get 2 with a remainder of 110.
The next digit of our result is 2. 
Result so far: 160167.675362
If we take 690 away from 800, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 15:
345 can be fit into 1100 3 times, resulting in a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 160167.6753623
If we subtract 1035 from 1100, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 16:
The number 345 fits into 650 1 times, leaving a remainder of 305.
Use 1 as the next digit of our solution. 
Result so far: 160167.67536231
Subtracting 345 from 650 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

After the division, we end up with 160167.67536231 and a remainder of 3.05e-07.
