We're dividing 403742 by 49 
The aim is to understand the frequency of 49 in 403742.

Moving on to step 1:
The number 49 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 49

Step 2:
The number 49 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 49

Advancing to step 3:
49 can be fit into 403 8 times, resulting in a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 392 from 403 to get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 49

Step 4:
49 can be fit into 117 2 times, resulting in a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Deduct 98 from 117 and we're left with 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 49

Step 5:
49 goes into 194 3 times with a remainder of 47.
The next digit of our result is 3. 
Result so far: 823.0
Subtract 147 from 194 to get 47.
Bring next digit (2) of the dividend behind the 47 and repeat the process: 472 / 49

On to step 6:
If we divide 472 by 49, we get 9 and a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 8239.0
Subtracting 441 from 472 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
49 goes into 310 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 8239.6
Subtracting 294 from 310 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
The number 49 fits into 160 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 8239.63
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
130 divided by 49 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 8239.632
If we subtract 98 from 130, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
320 divided by 49 is 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 8239.6326
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 11:
When dividing 260 by 49, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 8239.63265
The remainder is 15 after subtracting 245 from 260.
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 12:
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: 8239.632653
Deduct 147 from 150 and we're left 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 13:
49 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 8239.632653
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 14:
When dividing 300 by 49, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 8239.63265306
Subtracting 294 from 300 leaves us 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.

After the division, we end up with 8239.63265306 and a remainder of 6e-09.
