53079349 ÷ 230 
The aim is to understand the frequency of 230 in 53079349.

On to step 1:
If we divide 5 by 230, 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.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 230

On to step 2:
When dividing 53 by 230, we get 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Append the next digit (0) from the dividend to 53 and continue with: 530 / 230

Step 3:
When dividing 530 by 230, we get 2 with a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 460 from 530, we get 70.
Include the next digit (7) from the dividend after 70, then repeat: 707 / 230

Moving on to step 4:
230 goes into 707 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 690 from 707 leaves us with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 230

Step 5:
If we divide 179 by 230, we get 0 and a remainder of 179.
Write down 0 as next digit of the result. 
Result so far: 230.0
Deduct 0 from 179 and we're left with 179.
Grab the next digit (3) from the dividend, add it to 179, then carry on: 1793 / 230

Going ahead to step 6:
230 can be fit into 1793 7 times, resulting in a remainder of 183.
Use 7 as the next digit of our solution. 
Result so far: 2307.0
Subtracting 1610 from 1793 leaves us with 183.
Append the next digit (4) from the dividend to 183 and continue with: 1834 / 230

Moving on to step 7:
230 goes into 1834 7 times with a remainder of 224.
The number 7 becomes the next digit in our result. 
Result so far: 23077.0
If we subtract 1610 from 1834, we get 224.
Grab the next digit (9) from the dividend, add it to 224, then carry on: 2249 / 230

Moving on to step 8:
The number 230 fits into 2249 9 times, leaving a remainder of 179.
Use 9 as the next digit of our solution. 
Result so far: 230779.0
The remainder is 179 after subtracting 2070 from 2249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 9:
1790 divided by 230 is 7 with a remainder of 180.
The number 7 becomes the next digit in our result. 
Result so far: 230779.7
Subtract 1610 from 1790 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
When dividing 1800 by 230, we get 7 with a remainder of 190.
Write down 7 as next digit of the result. 
Result so far: 230779.77
Subtracting 1610 from 1800 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final result is 230779.77 with a remainder of 0.19.
