We look at the division of 23581881 by 483 
The aim is to understand the frequency of 483 in 23581881.

Going ahead to step 1:
483 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 483

On to step 2:
483 goes into 23 0 times with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 483

Step 3:
The number 483 fits into 235 0 times, leaving a remainder of 235.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 235 after subtracting 0 from 235.
Grab the next digit (8) from the dividend, add it to 235, then carry on: 2358 / 483

Moving on to step 4:
The number 483 fits into 2358 4 times, leaving a remainder of 426.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 426 after subtracting 1932 from 2358.
Take the next digit (1) from the dividend and append it to 426, then repeat: 4261 / 483

On to step 5:
483 goes into 4261 8 times with a remainder of 397.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 3864 from 4261 to get 397.
Grab the next digit (8) from the dividend, add it to 397, then carry on: 3978 / 483

Going ahead to step 6:
If we divide 3978 by 483, we get 8 and a remainder of 114.
The next digit of our result is 8. 
Result so far: 488.0
Deduct 3864 from 3978 and we're left with 114.
Take the next digit (8) from the dividend and append it to 114, then repeat: 1148 / 483

Step 7:
If we divide 1148 by 483, we get 2 and a remainder of 182.
Record the quotient 2 as the next digit in the result. 
Result so far: 4882.0
Deduct 966 from 1148 and we're left with 182.
Take the next digit (1) from the dividend and append it to 182, then repeat: 1821 / 483

Going ahead to step 8:
The number 483 fits into 1821 3 times, leaving a remainder of 372.
The number 3 becomes the next digit in our result. 
Result so far: 48823.0
If we subtract 1449 from 1821, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 9:
483 goes into 3720 7 times with a remainder of 339.
The number 7 becomes the next digit in our result. 
Result so far: 48823.7
If we subtract 3381 from 3720, we get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 10:
3390 divided by 483 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 48823.77
Deduct 3381 from 3390 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 48823.77, with a leftover of 0.009.
