478351 ÷ 49 
The aim is to understand the frequency of 49 in 478351.

Going ahead to step 1:
When dividing 4 by 49, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 49

Advancing to step 2:
If we divide 47 by 49, we get 0 and a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 49

On to step 3:
If we divide 478 by 49, we get 9 and a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 441 from 478 and we're left with 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 49

Advancing to step 4:
373 divided by 49 is 7 with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Subtract 343 from 373 to get 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 49

Let's proceed to step 5:
When dividing 305 by 49, we get 6 with a remainder of 11.
The next digit of our result is 6. 
Result so far: 976.0
If we subtract 294 from 305, we get 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 49

Going ahead to step 6:
49 can be fit into 111 2 times, resulting in a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 9762.0
If we subtract 98 from 111, 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.

Moving on to step 7:
49 can be fit into 130 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 9762.2
Deduct 98 from 130 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
When dividing 320 by 49, we get 6 with a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 9762.26
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
The number 49 fits into 260 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 9762.265
Subtracting 245 from 260 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
49 goes into 150 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 9762.2653
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
30 divided by 49 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 9762.2653
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
The number 49 fits into 300 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 9762.265306
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
The number 49 fits into 60 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 9762.2653061
If we take 49 away from 60, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
49 can be fit into 110 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 9762.26530612
Subtracting 98 from 110 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 9762.26530612, with a leftover of 1.2e-08.
