We're dividing 163925 by 49 
The aim is to understand the frequency of 49 in 163925.

Step 1:
If we divide 1 by 49, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 49

Let's proceed to step 2:
The number 49 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 49

Advancing to step 3:
163 divided by 49 is 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 147 from 163, we get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 49

Advancing to step 4:
When dividing 169 by 49, we get 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 33.0
The remainder is 22 after subtracting 147 from 169.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 49

On to step 5:
The number 49 fits into 222 4 times, leaving a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 334.0
Deduct 196 from 222 and we're left with 26.
Include the next digit (5) from the dividend after 26, then repeat: 265 / 49

Moving on to step 6:
If we divide 265 by 49, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 3345.0
The remainder is 20 after subtracting 245 from 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
200 divided by 49 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 3345.4
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
40 divided by 49 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3345.4
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
49 goes into 400 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 3345.408
Subtract 392 from 400 to 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.

Advancing to step 10:
When dividing 80 by 49, we get 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 3345.4081
If we subtract 49 from 80, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
The number 49 fits into 310 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 3345.40816
The remainder is 16 after subtracting 294 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
The number 49 fits into 160 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3345.408163
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
49 goes into 130 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 3345.4081632
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.

Let's proceed to step 14:
320 divided by 49 is 6 with a remainder of 26.
The next digit of our result is 6. 
Result so far: 3345.40816326
Subtract 294 from 320 to 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.

The quotient of the division is 3345.40816326, and the remainder is 2.6e-08.
