Let's divide 23997578 by 223
The aim is to understand the frequency of 223 in 23997578.

Step 1:
223 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 223

On to step 2:
223 can be fit into 23 0 times, resulting in a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 223

On to step 3:
223 can be fit into 239 1 times, resulting in a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 223 from 239 leaves us with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 223

On to step 4:
If we divide 169 by 223, we get 0 and a remainder of 169.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 169 after subtracting 0 from 169.
Grab the next digit (7) from the dividend, add it to 169, then carry on: 1697 / 223

Let's proceed to step 5:
When dividing 1697 by 223, we get 7 with a remainder of 136.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we subtract 1561 from 1697, we get 136.
Append the next digit (5) from the dividend to 136 and continue with: 1365 / 223

On to step 6:
223 goes into 1365 6 times with a remainder of 27.
The next digit of our result is 6. 
Result so far: 1076.0
If we take 1338 away from 1365, we end up with 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 223

Advancing to step 7:
The number 223 fits into 277 1 times, leaving a remainder of 54.
The next digit of our result is 1. 
Result so far: 10761.0
Deduct 223 from 277 and we're left with 54.
Append the next digit (8) from the dividend to 54 and continue with: 548 / 223

Moving on to step 8:
548 divided by 223 is 2 with a remainder of 102.
Put 2 as the next digit of the answer. 
Result so far: 107612.0
Deduct 446 from 548 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 9:
If we divide 1020 by 223, we get 4 and a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 107612.4
Deduct 892 from 1020 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 10:
When dividing 1280 by 223, we get 5 with a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 107612.45
Deduct 1115 from 1280 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 11:
223 can be fit into 1650 7 times, resulting in a remainder of 89.
Put 7 as the next digit of the answer. 
Result so far: 107612.457
Deduct 1561 from 1650 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 12:
223 can be fit into 890 3 times, resulting in a remainder of 221.
Use 3 as the next digit of our solution. 
Result so far: 107612.4573
Deduct 669 from 890 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 13:
The number 223 fits into 2210 9 times, leaving a remainder of 203.
Record the quotient 9 as the next digit in the result. 
Result so far: 107612.45739
Deduct 2007 from 2210 and we're left with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

On to step 14:
223 can be fit into 2030 9 times, resulting in a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 107612.457399
Subtracting 2007 from 2030 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

After the division, we end up with 107612.457399 and a remainder of 2.3e-06.
