Let's divide 266161 by 49
The aim is to understand the frequency of 49 in 266161.

On to step 1:
When dividing 2 by 49, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 49

Moving on to step 2:
When dividing 26 by 49, we get 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 49

Advancing to step 3:
49 goes into 266 5 times with a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 245 from 266 leaves us with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 49

On to step 4:
The number 49 fits into 211 4 times, leaving a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 54.0
If we subtract 196 from 211, we get 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 49

Step 5:
When dividing 156 by 49, we get 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 543.0
If we subtract 147 from 156, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 49

Step 6:
49 goes into 91 1 times with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 5431.0
Subtracting 49 from 91 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.

Moving on to step 7:
When dividing 420 by 49, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 5431.8
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 8:
49 goes into 280 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 5431.85
Subtract 245 from 280 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
The number 49 fits into 350 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 5431.857
If we take 343 away from 350, we end up with 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 10:
49 can be fit into 70 1 times, resulting in a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 5431.8571
The remainder is 21 after subtracting 49 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
The number 49 fits into 210 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 5431.85714
Deduct 196 from 210 and we're left 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.

Let's proceed to step 12:
When dividing 140 by 49, we get 2 with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 5431.857142
If we take 98 away from 140, we end up 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.

Step 13:
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: 5431.8571428
If we take 392 away from 420, we end up 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.

Advancing to step 14:
When dividing 280 by 49, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 5431.85714285
The remainder is 35 after subtracting 245 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 5431.85714285, with a leftover of 3.5e-08.
