We divide 787644 by 49
The aim is to understand the frequency of 49 in 787644.

Moving on to step 1:
7 divided by 49 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 49

Moving on to step 2:
When dividing 78 by 49, we get 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 49 from 78, we get 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 49

On to step 3:
When dividing 297 by 49, we get 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 294 from 297, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 49

Step 4:
When dividing 36 by 49, we get 0 with a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 160.0
The remainder is 36 after subtracting 0 from 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 49

Going ahead to step 5:
49 can be fit into 364 7 times, resulting in a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 1607.0
If we take 343 away from 364, we end up with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 49

Advancing to step 6:
If we divide 214 by 49, we get 4 and a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 16074.0
Deduct 196 from 214 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
When dividing 180 by 49, we get 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 16074.3
Deduct 147 from 180 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 8:
330 divided by 49 is 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 16074.36
If we subtract 294 from 330, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
49 can be fit into 360 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 16074.367
Deduct 343 from 360 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
49 goes into 170 3 times with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 16074.3673
Subtract 147 from 170 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 11:
When dividing 230 by 49, we get 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 16074.36734
Subtracting 196 from 230 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
49 goes into 340 6 times with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 16074.367346
Deduct 294 from 340 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 13:
The number 49 fits into 460 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 16074.3673469
If we subtract 441 from 460, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
49 goes into 190 3 times with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 16074.36734693
If we take 147 away from 190, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

After the division, we end up with 16074.36734693 and a remainder of 4.3e-08.
