We divide 72081944 by 223
The aim is to understand the frequency of 223 in 72081944.

Going ahead to step 1:
223 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 223

Going ahead to step 2:
72 divided by 223 is 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 223

On to step 3:
223 can be fit into 720 3 times, resulting in a remainder of 51.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 669 from 720 to get 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 223

Going ahead to step 4:
223 goes into 518 2 times with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 446 from 518 to get 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 223

Moving on to step 5:
The number 223 fits into 721 3 times, leaving a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 323.0
If we subtract 669 from 721, we get 52.
Append the next digit (9) from the dividend to 52 and continue with: 529 / 223

Advancing to step 6:
223 can be fit into 529 2 times, resulting in a remainder of 83.
The number 2 becomes the next digit in our result. 
Result so far: 3232.0
Subtracting 446 from 529 leaves us with 83.
Fetch the next digit (4) from the dividend, attach it to 83 and continue: 834 / 223

Step 7:
When dividing 834 by 223, we get 3 with a remainder of 165.
Use 3 as the next digit of our solution. 
Result so far: 32323.0
If we take 669 away from 834, we end up with 165.
Grab the next digit (4) from the dividend, add it to 165, then carry on: 1654 / 223

Advancing to step 8:
If we divide 1654 by 223, we get 7 and a remainder of 93.
The next digit of our result is 7. 
Result so far: 323237.0
The remainder is 93 after subtracting 1561 from 1654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 9:
When dividing 930 by 223, we get 4 with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 323237.4
If we take 892 away from 930, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
If we divide 380 by 223, we get 1 and a remainder of 157.
The number 1 becomes the next digit in our result. 
Result so far: 323237.41
Deduct 223 from 380 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 11:
The number 223 fits into 1570 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 323237.417
Subtract 1561 from 1570 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
The number 223 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 323237.417
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 13:
223 can be fit into 900 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 323237.41704
If we subtract 892 from 900, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
223 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 323237.41704
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 15:
The number 223 fits into 800 3 times, leaving a remainder of 131.
Use 3 as the next digit of our solution. 
Result so far: 323237.4170403
Deduct 669 from 800 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 16:
1310 divided by 223 is 5 with a remainder of 195.
Put 5 as the next digit of the answer. 
Result so far: 323237.41704035
If we subtract 1115 from 1310, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

The final outcome is 323237.41704035, with a leftover of 1.95e-07.
