We look at the division of 71435270 by 49 
The aim is to understand the frequency of 49 in 71435270.

Step 1:
49 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 49

Advancing to step 2:
When dividing 71 by 49, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 49 from 71 to get 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 49

Let's proceed to step 3:
224 divided by 49 is 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 196 from 224 leaves us with 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 49

Going ahead to step 4:
When dividing 283 by 49, we get 5 with a remainder of 38.
The next digit of our result is 5. 
Result so far: 145.0
If we subtract 245 from 283, we get 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 49

Moving on to step 5:
When dividing 385 by 49, we get 7 with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 1457.0
If we take 343 away from 385, we end up with 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 49

Advancing to step 6:
If we divide 422 by 49, we get 8 and a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 14578.0
If we take 392 away from 422, we end up with 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 49

Going ahead to step 7:
The number 49 fits into 307 6 times, leaving a remainder of 13.
The next digit of our result is 6. 
Result so far: 145786.0
Subtracting 294 from 307 leaves us with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 49

Advancing to step 8:
When dividing 130 by 49, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 1457862.0
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.

Moving on to step 9:
320 divided by 49 is 6 with a remainder of 26.
The next digit of our result is 6. 
Result so far: 1457862.6
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.

Moving on to step 10:
49 goes into 260 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1457862.65
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.

Moving on to step 11:
49 can be fit into 150 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 1457862.653
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.

On to step 12:
49 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1457862.653
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.

Let's proceed to step 13:
300 divided by 49 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 1457862.65306
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
49 goes into 60 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1457862.653061
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.

Moving on to step 15:
When dividing 110 by 49, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 1457862.6530612
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.

Advancing to step 16:
120 divided by 49 is 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 1457862.65306122
If we subtract 98 from 120, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 1457862.65306122, with a leftover of 2.2e-08.
