We divide 423280 by 49
The aim is to understand the frequency of 49 in 423280.

Advancing to step 1:
4 divided by 49 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 49

Going ahead to step 2:
When dividing 42 by 49, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 49

On to step 3:
49 can be fit into 423 8 times, resulting in a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 392 from 423 leaves us with 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 49

Step 4:
If we divide 312 by 49, we get 6 and a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtract 294 from 312 to get 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 49

Advancing to step 5:
If we divide 188 by 49, we get 3 and a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 863.0
If we take 147 away from 188, we end up with 41.
Bring next digit (0) of the dividend behind the 41 and repeat the process: 410 / 49

On to step 6:
When dividing 410 by 49, we get 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 8638.0
If we take 392 away from 410, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
When dividing 180 by 49, we get 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 8638.3
Subtract 147 from 180 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 8:
49 can be fit into 330 6 times, resulting in a remainder of 36.
The next digit of our result is 6. 
Result so far: 8638.36
If we subtract 294 from 330, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
49 can be fit into 360 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 8638.367
The remainder is 17 after subtracting 343 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
The number 49 fits into 170 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 8638.3673
Subtracting 147 from 170 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 11:
49 goes into 230 4 times with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 8638.36734
Subtract 196 from 230 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
340 divided by 49 is 6 with a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 8638.367346
Subtracting 294 from 340 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 13:
If we divide 460 by 49, we get 9 and a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 8638.3673469
The remainder is 19 after subtracting 441 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
When dividing 190 by 49, we get 3 with a remainder of 43.
The next digit of our result is 3. 
Result so far: 8638.36734693
If we subtract 147 from 190, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final outcome is 8638.36734693, with a leftover of 4.3e-08.
