We look at the division of 49773505 by 406 
The aim is to understand the frequency of 406 in 49773505.

Step 1:
The number 406 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 406

Going ahead to step 2:
406 goes into 49 0 times with a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 406

On to step 3:
406 can be fit into 497 1 times, resulting in a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 406 from 497, we get 91.
Include the next digit (7) from the dividend after 91, then repeat: 917 / 406

Advancing to step 4:
917 divided by 406 is 2 with a remainder of 105.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 812 away from 917, we end up with 105.
Grab the next digit (3) from the dividend, add it to 105, then carry on: 1053 / 406

Moving on to step 5:
When dividing 1053 by 406, we get 2 with a remainder of 241.
The next digit of our result is 2. 
Result so far: 122.0
Deduct 812 from 1053 and we're left with 241.
Bring next digit (5) of the dividend behind the 241 and repeat the process: 2415 / 406

Going ahead to step 6:
When dividing 2415 by 406, we get 5 with a remainder of 385.
Write down 5 as next digit of the result. 
Result so far: 1225.0
Subtracting 2030 from 2415 leaves us with 385.
Grab the next digit (0) from the dividend, add it to 385, then carry on: 3850 / 406

Let's proceed to step 7:
The number 406 fits into 3850 9 times, leaving a remainder of 196.
Put 9 as the next digit of the answer. 
Result so far: 12259.0
Deduct 3654 from 3850 and we're left with 196.
Fetch the next digit (5) from the dividend, attach it to 196 and continue: 1965 / 406

Moving on to step 8:
The number 406 fits into 1965 4 times, leaving a remainder of 341.
Record the quotient 4 as the next digit in the result. 
Result so far: 122594.0
If we take 1624 away from 1965, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Step 9:
If we divide 3410 by 406, we get 8 and a remainder of 162.
Put 8 as the next digit of the answer. 
Result so far: 122594.8
Subtract 3248 from 3410 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 10:
If we divide 1620 by 406, we get 3 and a remainder of 402.
The next digit of our result is 3. 
Result so far: 122594.83
Subtracting 1218 from 1620 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Let's proceed to step 11:
4020 divided by 406 is 9 with a remainder of 366.
Record the quotient 9 as the next digit in the result. 
Result so far: 122594.839
Subtract 3654 from 4020 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 12:
The number 406 fits into 3660 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 122594.8399
The remainder is 6 after subtracting 3654 from 3660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 122594.8399 and a remainder of 6e-05.
