We divide 75015772 by 223
The aim is to understand the frequency of 223 in 75015772.

Let's proceed to step 1:
223 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 223

On to step 2:
223 goes into 75 0 times with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Take the next digit (0) from the dividend and append it to 75, then repeat: 750 / 223

Going ahead to step 3:
750 divided by 223 is 3 with a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 669 away from 750, we end up with 81.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 223

Step 4:
The number 223 fits into 811 3 times, leaving a remainder of 142.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 669 from 811 and we're left with 142.
Append the next digit (5) from the dividend to 142 and continue with: 1425 / 223

On to step 5:
223 goes into 1425 6 times with a remainder of 87.
Write down 6 as next digit of the result. 
Result so far: 336.0
If we subtract 1338 from 1425, we get 87.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 223

On to step 6:
When dividing 877 by 223, we get 3 with a remainder of 208.
Put 3 as the next digit of the answer. 
Result so far: 3363.0
If we subtract 669 from 877, we get 208.
Append the next digit (7) from the dividend to 208 and continue with: 2087 / 223

Step 7:
When dividing 2087 by 223, we get 9 with a remainder of 80.
The next digit of our result is 9. 
Result so far: 33639.0
If we take 2007 away from 2087, we end up with 80.
Fetch the next digit (2) from the dividend, attach it to 80 and continue: 802 / 223

Going ahead to step 8:
The number 223 fits into 802 3 times, leaving a remainder of 133.
Put 3 as the next digit of the answer. 
Result so far: 336393.0
Subtracting 669 from 802 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 9:
1330 divided by 223 is 5 with a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 336393.5
Subtracting 1115 from 1330 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 10:
When dividing 2150 by 223, we get 9 with a remainder of 143.
The number 9 becomes the next digit in our result. 
Result so far: 336393.59
Subtracting 2007 from 2150 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Step 11:
If we divide 1430 by 223, we get 6 and a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 336393.596
If we subtract 1338 from 1430, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 12:
The number 223 fits into 920 4 times, leaving a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 336393.5964
If we take 892 away from 920, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
223 goes into 280 1 times with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 336393.59641
Subtracting 223 from 280 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 14:
223 can be fit into 570 2 times, resulting in a remainder of 124.
Use 2 as the next digit of our solution. 
Result so far: 336393.596412
Subtract 446 from 570 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 15:
The number 223 fits into 1240 5 times, leaving a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 336393.5964125
If we subtract 1115 from 1240, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 16:
223 goes into 1250 5 times with a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 336393.59641255
Subtract 1115 from 1250 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final result is 336393.59641255 with a remainder of 1.35e-07.
