We're dividing 921398 by 49 
The aim is to understand the frequency of 49 in 921398.

Let's proceed to step 1:
49 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 49

On to step 2:
49 goes into 92 1 times with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 49 away from 92, we end up with 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 49

Moving on to step 3:
49 goes into 431 8 times with a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 392 from 431 to get 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 49

Step 4:
49 goes into 393 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 188.0
The remainder is 1 after subtracting 392 from 393.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 49

Let's proceed to step 5:
49 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 1880.0
If we subtract 0 from 19, we get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 49

Moving on to step 6:
The number 49 fits into 198 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 18804.0
Subtract 196 from 198 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
49 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 18804.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
49 goes into 200 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 18804.04
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
The number 49 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 18804.04
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
The number 49 fits into 400 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 18804.0408
Subtracting 392 from 400 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
The number 49 fits into 80 1 times, leaving a remainder of 31.
The next digit of our result is 1. 
Result so far: 18804.04081
The remainder is 31 after subtracting 49 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 12:
49 can be fit into 310 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 18804.040816
If we subtract 294 from 310, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
When dividing 160 by 49, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 18804.0408163
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 14:
49 goes into 130 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 18804.04081632
The remainder is 32 after subtracting 98 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 18804.04081632, with a leftover of 3.2e-08.
