Let's divide 57980941 by 345
The aim is to understand the frequency of 345 in 57980941.

Going ahead to step 1:
345 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 345

Let's proceed to step 2:
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: 0.0
Subtracting 0 from 57 leaves us with 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 345

Moving on to step 3:
345 goes into 579 1 times with a remainder of 234.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 345 from 579, we get 234.
Include the next digit (8) from the dividend after 234, then repeat: 2348 / 345

Let's proceed to step 4:
If we divide 2348 by 345, we get 6 and a remainder of 278.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 278 after subtracting 2070 from 2348.
Take the next digit (0) from the dividend and append it to 278, then repeat: 2780 / 345

Step 5:
345 can be fit into 2780 8 times, resulting in a remainder of 20.
The next digit of our result is 8. 
Result so far: 168.0
If we take 2760 away from 2780, we end up with 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 345

Advancing to step 6:
If we divide 209 by 345, we get 0 and a remainder of 209.
The next digit of our result is 0. 
Result so far: 1680.0
The remainder is 209 after subtracting 0 from 209.
Fetch the next digit (4) from the dividend, attach it to 209 and continue: 2094 / 345

Let's proceed to step 7:
If we divide 2094 by 345, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 16806.0
The remainder is 24 after subtracting 2070 from 2094.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 345

Advancing to step 8:
241 divided by 345 is 0 with a remainder of 241.
Use 0 as the next digit of our solution. 
Result so far: 168060.0
Deduct 0 from 241 and we're left with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Going ahead to step 9:
345 goes into 2410 6 times with a remainder of 340.
Put 6 as the next digit of the answer. 
Result so far: 168060.6
Deduct 2070 from 2410 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 10:
345 can be fit into 3400 9 times, resulting in a remainder of 295.
Record the quotient 9 as the next digit in the result. 
Result so far: 168060.69
The remainder is 295 after subtracting 3105 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 11:
2950 divided by 345 is 8 with a remainder of 190.
Use 8 as the next digit of our solution. 
Result so far: 168060.698
If we subtract 2760 from 2950, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 12:
When dividing 1900 by 345, we get 5 with a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 168060.6985
Subtract 1725 from 1900 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 13:
When dividing 1750 by 345, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 168060.69855
Subtracting 1725 from 1750 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 168060.69855 and a remainder of 2.5e-05.
