We look at the division of 408432 by 49 
The aim is to understand the frequency of 49 in 408432.

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 take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 49

Advancing to step 2:
49 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 49

Moving on to step 3:
The number 49 fits into 408 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 8.0
If we take 392 away from 408, we end up with 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 49

Going ahead to step 4:
49 goes into 164 3 times with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 83.0
Deduct 147 from 164 and we're left with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 49

Going ahead to step 5:
The number 49 fits into 173 3 times, leaving a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 833.0
If we take 147 away from 173, we end up with 26.
Take the next digit (2) from the dividend and append it to 26, then repeat: 262 / 49

Advancing to step 6:
When dividing 262 by 49, we get 5 with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 8335.0
Subtract 245 from 262 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
49 goes into 170 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 8335.3
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.

Going ahead to step 8:
When dividing 230 by 49, we get 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 8335.34
If we take 196 away from 230, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
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: 8335.346
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.

Advancing to step 10:
49 goes into 460 9 times with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 8335.3469
Subtracting 441 from 460 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
If we divide 190 by 49, we get 3 and a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 8335.34693
If we take 147 away from 190, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 12:
49 can be fit into 430 8 times, resulting in a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 8335.346938
Deduct 392 from 430 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
49 goes into 380 7 times with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 8335.3469387
If we subtract 343 from 380, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 14:
370 divided by 49 is 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 8335.34693877
If we subtract 343 from 370, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 8335.34693877 with a balance of 2.7e-08.
