We divide 579872 by 49
The aim is to understand the frequency of 49 in 579872.

Let's proceed to step 1:
If we divide 5 by 49, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 49

Let's proceed to step 2:
The number 49 fits into 57 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 49 from 57 leaves us with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 49

On to step 3:
49 goes into 89 1 times with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 40 after subtracting 49 from 89.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 49

Advancing to step 4:
49 goes into 408 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 118.0
Deduct 392 from 408 and we're left with 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 49

Let's proceed to step 5:
If we divide 167 by 49, we get 3 and a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 1183.0
The remainder is 20 after subtracting 147 from 167.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 49

Going ahead to step 6:
The number 49 fits into 202 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 11834.0
If we subtract 196 from 202, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
49 can be fit into 60 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 11834.1
If we subtract 49 from 60, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
49 can be fit into 110 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 11834.12
If we take 98 away from 110, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
When dividing 120 by 49, we get 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 11834.122
The remainder is 22 after subtracting 98 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 11834.122 with a remainder of 0.0022.
