We look at the division of 90667 by 49 
The aim is to understand the frequency of 49 in 90667.

Going ahead to step 1:
The number 49 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 49

Moving on to step 2:
The number 49 fits into 90 1 times, leaving a remainder of 41.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 49 from 90 to get 41.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 49

Going ahead to step 3:
416 divided by 49 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 392 away from 416, we end up with 24.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 49

Moving on to step 4:
If we divide 246 by 49, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
Deduct 245 from 246 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 49

Going ahead to step 5:
49 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 1850.0
Subtract 0 from 17 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 6:
49 goes into 170 3 times with a remainder of 23.
The next digit of our result is 3. 
Result so far: 1850.3
Deduct 147 from 170 and we're left 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.

Moving on to step 7:
If we divide 230 by 49, we get 4 and a remainder of 34.
The next digit of our result is 4. 
Result so far: 1850.34
Deduct 196 from 230 and we're left 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.

Step 8:
49 goes into 340 6 times with a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 1850.346
If we take 294 away from 340, we end up 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.

Step 9:
If we divide 460 by 49, we get 9 and a remainder of 19.
The next digit of our result is 9. 
Result so far: 1850.3469
Subtract 441 from 460 to get 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 10:
190 divided by 49 is 3 with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 1850.34693
Subtracting 147 from 190 leaves us 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.

On to step 11:
430 divided by 49 is 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 1850.346938
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.

Let's proceed to step 12:
When dividing 380 by 49, we get 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 1850.3469387
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.

Step 13:
370 divided by 49 is 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 1850.34693877
Subtracting 343 from 370 leaves us with 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 1850.34693877 with a balance of 2.7e-08.
