86263316 divided by 223 
The aim is to understand the frequency of 223 in 86263316.

On to step 1:
223 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 223

On to step 2:
The number 223 fits into 86 0 times, leaving a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Take the next digit (2) from the dividend and append it to 86, then repeat: 862 / 223

Moving on to step 3:
223 goes into 862 3 times with a remainder of 193.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 193 after subtracting 669 from 862.
Take the next digit (6) from the dividend and append it to 193, then repeat: 1936 / 223

Advancing to step 4:
1936 divided by 223 is 8 with a remainder of 152.
The next digit of our result is 8. 
Result so far: 38.0
Subtract 1784 from 1936 to get 152.
Grab the next digit (3) from the dividend, add it to 152, then carry on: 1523 / 223

Advancing to step 5:
When dividing 1523 by 223, we get 6 with a remainder of 185.
Use 6 as the next digit of our solution. 
Result so far: 386.0
The remainder is 185 after subtracting 1338 from 1523.
Append the next digit (3) from the dividend to 185 and continue with: 1853 / 223

Let's proceed to step 6:
If we divide 1853 by 223, we get 8 and a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 3868.0
The remainder is 69 after subtracting 1784 from 1853.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 223

Going ahead to step 7:
If we divide 691 by 223, we get 3 and a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 38683.0
If we subtract 669 from 691, we get 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 223

On to step 8:
If we divide 226 by 223, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 386831.0
If we take 223 away from 226, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
The number 223 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 386831.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
223 can be fit into 300 1 times, resulting in a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 386831.01
If we take 223 away from 300, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 11:
The number 223 fits into 770 3 times, leaving a remainder of 101.
The number 3 becomes the next digit in our result. 
Result so far: 386831.013
Subtracting 669 from 770 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 12:
223 can be fit into 1010 4 times, resulting in a remainder of 118.
The number 4 becomes the next digit in our result. 
Result so far: 386831.0134
If we take 892 away from 1010, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 13:
223 goes into 1180 5 times with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 386831.01345
Subtracting 1115 from 1180 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 14:
When dividing 650 by 223, we get 2 with a remainder of 204.
Record the quotient 2 as the next digit in the result. 
Result so far: 386831.013452
If we subtract 446 from 650, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 15:
223 goes into 2040 9 times with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 386831.0134529
If we take 2007 away from 2040, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 16:
If we divide 330 by 223, we get 1 and a remainder of 107.
Use 1 as the next digit of our solution. 
Result so far: 386831.01345291
If we subtract 223 from 330, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

After the division, we end up with 386831.01345291 and a remainder of 1.07e-07.
