837778 divided by 49 
The aim is to understand the frequency of 49 in 837778.

Let's proceed to step 1:
When dividing 8 by 49, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 49

Going ahead to step 2:
49 goes into 83 1 times with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 49 from 83 leaves us with 34.
Append the next digit (7) from the dividend to 34 and continue with: 347 / 49

Advancing to step 3:
49 can be fit into 347 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 343 from 347 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 49

Moving on to step 4:
49 goes into 47 0 times with a remainder of 47.
The next digit of our result is 0. 
Result so far: 170.0
Deduct 0 from 47 and we're left with 47.
Append the next digit (7) from the dividend to 47 and continue with: 477 / 49

Advancing to step 5:
477 divided by 49 is 9 with a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 1709.0
The remainder is 36 after subtracting 441 from 477.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 49

Advancing to step 6:
49 can be fit into 368 7 times, resulting in a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 17097.0
If we take 343 away from 368, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
When dividing 250 by 49, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 17097.5
If we take 245 away from 250, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
49 can be fit into 50 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 17097.51
Subtract 49 from 50 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
49 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 17097.51
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
100 divided by 49 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 17097.5102
Subtract 98 from 100 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
When dividing 20 by 49, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 17097.5102
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
49 goes into 200 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 17097.510204
If we subtract 196 from 200, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
49 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 17097.510204
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
400 divided by 49 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 17097.51020408
If we subtract 392 from 400, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 17097.51020408, with a leftover of 8e-09.
