41998401 divided by 308 
The aim is to understand the frequency of 308 in 41998401.

Moving on to step 1:
The number 308 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 308

Going ahead to step 2:
When dividing 41 by 308, we get 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 41 and we're left with 41.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 308

Step 3:
308 can be fit into 419 1 times, resulting in a remainder of 111.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 308 from 419 and we're left with 111.
Grab the next digit (9) from the dividend, add it to 111, then carry on: 1119 / 308

Moving on to step 4:
If we divide 1119 by 308, we get 3 and a remainder of 195.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 924 away from 1119, we end up with 195.
Append the next digit (8) from the dividend to 195 and continue with: 1958 / 308

On to step 5:
If we divide 1958 by 308, we get 6 and a remainder of 110.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
If we subtract 1848 from 1958, we get 110.
Append the next digit (4) from the dividend to 110 and continue with: 1104 / 308

Step 6:
When dividing 1104 by 308, we get 3 with a remainder of 180.
The number 3 becomes the next digit in our result. 
Result so far: 1363.0
If we take 924 away from 1104, we end up with 180.
Grab the next digit (0) from the dividend, add it to 180, then carry on: 1800 / 308

Let's proceed to step 7:
308 can be fit into 1800 5 times, resulting in a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 13635.0
Subtracting 1540 from 1800 leaves us with 260.
Append the next digit (1) from the dividend to 260 and continue with: 2601 / 308

Advancing to step 8:
If we divide 2601 by 308, we get 8 and a remainder of 137.
Use 8 as the next digit of our solution. 
Result so far: 136358.0
If we take 2464 away from 2601, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 9:
308 can be fit into 1370 4 times, resulting in a remainder of 138.
Write down 4 as next digit of the result. 
Result so far: 136358.4
Subtract 1232 from 1370 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 10:
The number 308 fits into 1380 4 times, leaving a remainder of 148.
Write down 4 as next digit of the result. 
Result so far: 136358.44
If we subtract 1232 from 1380, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The final outcome is 136358.44, with a leftover of 0.148.
