817439 ÷ 49 
The aim is to understand the frequency of 49 in 817439.

Going ahead to step 1:
If we divide 8 by 49, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 49

Moving on to step 2:
When dividing 81 by 49, we get 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 49 from 81 to get 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 49

Going ahead to step 3:
If we divide 327 by 49, we get 6 and a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 33 after subtracting 294 from 327.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 49

Step 4:
49 goes into 334 6 times with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 166.0
The remainder is 40 after subtracting 294 from 334.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 49

Moving on to step 5:
The number 49 fits into 403 8 times, leaving a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 1668.0
The remainder is 11 after subtracting 392 from 403.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 49

Moving on to step 6:
When dividing 119 by 49, we get 2 with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 16682.0
If we subtract 98 from 119, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
If we divide 210 by 49, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 16682.4
If we take 196 away from 210, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
49 goes into 140 2 times with a remainder of 42.
The next digit of our result is 2. 
Result so far: 16682.42
Deduct 98 from 140 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
If we divide 420 by 49, we get 8 and a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 16682.428
Subtracting 392 from 420 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
The number 49 fits into 280 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 16682.4285
Subtracting 245 from 280 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
The number 49 fits into 350 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 16682.42857
Subtract 343 from 350 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
The number 49 fits into 70 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 16682.428571
If we subtract 49 from 70, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
When dividing 210 by 49, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 16682.4285714
The remainder is 14 after subtracting 196 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
The number 49 fits into 140 2 times, leaving a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 16682.42857142
Subtracting 98 from 140 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 16682.42857142, with a leftover of 4.2e-08.
