183870 divided by 49 
The aim is to understand the frequency of 49 in 183870.

Going ahead to step 1:
1 divided by 49 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 49

Going ahead to step 2:
49 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 49

On to step 3:
49 goes into 183 3 times with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 147 away from 183, we end up with 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 49

Advancing to step 4:
49 can be fit into 368 7 times, resulting in a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtract 343 from 368 to get 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 49

Let's proceed to step 5:
49 can be fit into 257 5 times, resulting in a remainder of 12.
The next digit of our result is 5. 
Result so far: 375.0
Subtract 245 from 257 to get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 49

On to step 6:
If we divide 120 by 49, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 3752.0
Subtracting 98 from 120 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
The number 49 fits into 220 4 times, leaving a remainder of 24.
The next digit of our result is 4. 
Result so far: 3752.4
Subtracting 196 from 220 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
When dividing 240 by 49, we get 4 with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 3752.44
Subtracting 196 from 240 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 3752.44 and a remainder of 0.044.
