We're dividing 23835979 by 221 
The aim is to understand the frequency of 221 in 23835979.

Let's proceed to step 1:
221 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 221

Advancing to step 2:
The number 221 fits into 23 0 times, leaving a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 221

Going ahead to step 3:
When dividing 238 by 221, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 221 from 238, we get 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 221

Going ahead to step 4:
When dividing 173 by 221, we get 0 with a remainder of 173.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 173, we end up with 173.
Fetch the next digit (5) from the dividend, attach it to 173 and continue: 1735 / 221

On to step 5:
221 can be fit into 1735 7 times, resulting in a remainder of 188.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
The remainder is 188 after subtracting 1547 from 1735.
Append the next digit (9) from the dividend to 188 and continue with: 1889 / 221

Let's proceed to step 6:
221 goes into 1889 8 times with a remainder of 121.
Write down 8 as next digit of the result. 
Result so far: 1078.0
If we take 1768 away from 1889, we end up with 121.
Bring next digit (7) of the dividend behind the 121 and repeat the process: 1217 / 221

Advancing to step 7:
221 goes into 1217 5 times with a remainder of 112.
Record the quotient 5 as the next digit in the result. 
Result so far: 10785.0
Subtract 1105 from 1217 to get 112.
Bring next digit (9) of the dividend behind the 112 and repeat the process: 1129 / 221

Going ahead to step 8:
221 goes into 1129 5 times with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 107855.0
Subtract 1105 from 1129 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
240 divided by 221 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 107855.1
Deduct 221 from 240 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
190 divided by 221 is 0 with a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 107855.1
Subtracting 0 from 190 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.

Going ahead to step 11:
If we divide 1900 by 221, we get 8 and a remainder of 132.
Write down 8 as next digit of the result. 
Result so far: 107855.108
Deduct 1768 from 1900 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 12:
221 goes into 1320 5 times with a remainder of 215.
The next digit of our result is 5. 
Result so far: 107855.1085
Subtract 1105 from 1320 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 13:
221 goes into 2150 9 times with a remainder of 161.
Record the quotient 9 as the next digit in the result. 
Result so far: 107855.10859
The remainder is 161 after subtracting 1989 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Moving on to step 14:
221 can be fit into 1610 7 times, resulting in a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 107855.108597
Subtract 1547 from 1610 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 15:
221 can be fit into 630 2 times, resulting in a remainder of 188.
Put 2 as the next digit of the answer. 
Result so far: 107855.1085972
Subtracting 442 from 630 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 16:
The number 221 fits into 1880 8 times, leaving a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 107855.10859728
The remainder is 112 after subtracting 1768 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

In conclusion, the division gives 107855.10859728 with a balance of 1.12e-07.
