21477 divided by 49 
The aim is to understand the frequency of 49 in 21477.

On to step 1:
2 divided by 49 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 49

Moving on to step 2:
When dividing 21 by 49, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 49

On to step 3:
214 divided by 49 is 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 196 from 214, we get 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 49

Step 4:
The number 49 fits into 187 3 times, leaving a remainder of 40.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 40 after subtracting 147 from 187.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 49

Advancing to step 5:
If we divide 407 by 49, we get 8 and a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 438.0
The remainder is 15 after subtracting 392 from 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 6:
49 can be fit into 150 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 438.3
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
30 divided by 49 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 438.3
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
49 can be fit into 300 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 438.306
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
60 divided by 49 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 438.3061
The remainder is 11 after subtracting 49 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
49 can be fit into 110 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 438.30612
Subtract 98 from 110 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
49 can be fit into 120 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 438.306122
Deduct 98 from 120 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 438.306122 with a balance of 2.2e-06.
