We divide 10515577 by 223
The aim is to understand the frequency of 223 in 10515577.

Advancing to step 1:
The number 223 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 223

Moving on to step 2:
When dividing 10 by 223, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 223

On to step 3:
When dividing 105 by 223, we get 0 with a remainder of 105.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 105 leaves us with 105.
Append the next digit (1) from the dividend to 105 and continue with: 1051 / 223

Advancing to step 4:
If we divide 1051 by 223, we get 4 and a remainder of 159.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 892 from 1051 and we're left with 159.
Take the next digit (5) from the dividend and append it to 159, then repeat: 1595 / 223

Going ahead to step 5:
If we divide 1595 by 223, we get 7 and a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtracting 1561 from 1595 leaves us with 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 223

Advancing to step 6:
223 can be fit into 345 1 times, resulting in a remainder of 122.
Write down 1 as next digit of the result. 
Result so far: 471.0
If we take 223 away from 345, we end up with 122.
Bring next digit (7) of the dividend behind the 122 and repeat the process: 1227 / 223

Going ahead to step 7:
223 can be fit into 1227 5 times, resulting in a remainder of 112.
Put 5 as the next digit of the answer. 
Result so far: 4715.0
Subtracting 1115 from 1227 leaves us with 112.
Bring next digit (7) of the dividend behind the 112 and repeat the process: 1127 / 223

Step 8:
1127 divided by 223 is 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 47155.0
If we take 1115 away from 1127, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
120 divided by 223 is 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 47155.0
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
If we divide 1200 by 223, we get 5 and a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 47155.05
Deduct 1115 from 1200 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 11:
If we divide 850 by 223, we get 3 and a remainder of 181.
The next digit of our result is 3. 
Result so far: 47155.053
Subtracting 669 from 850 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 12:
223 goes into 1810 8 times with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 47155.0538
Subtract 1784 from 1810 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
If we divide 260 by 223, we get 1 and a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 47155.05381
Subtracting 223 from 260 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 14:
223 can be fit into 370 1 times, resulting in a remainder of 147.
Use 1 as the next digit of our solution. 
Result so far: 47155.053811
Deduct 223 from 370 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

The final outcome is 47155.053811, with a leftover of 1.47e-05.
