99613600 ÷ 228 
The aim is to understand the frequency of 228 in 99613600.

Moving on to step 1:
9 divided by 228 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 228

Moving on to step 2:
228 goes into 99 0 times with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Fetch the next digit (6) from the dividend, attach it to 99 and continue: 996 / 228

Going ahead to step 3:
When dividing 996 by 228, we get 4 with a remainder of 84.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 84 after subtracting 912 from 996.
Bring next digit (1) of the dividend behind the 84 and repeat the process: 841 / 228

Step 4:
228 goes into 841 3 times with a remainder of 157.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 684 from 841, we get 157.
Include the next digit (3) from the dividend after 157, then repeat: 1573 / 228

Advancing to step 5:
When dividing 1573 by 228, we get 6 with a remainder of 205.
The number 6 becomes the next digit in our result. 
Result so far: 436.0
Deduct 1368 from 1573 and we're left with 205.
Bring next digit (6) of the dividend behind the 205 and repeat the process: 2056 / 228

Let's proceed to step 6:
The number 228 fits into 2056 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 4369.0
Deduct 2052 from 2056 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 228

Let's proceed to step 7:
228 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 43690.0
The remainder is 40 after subtracting 0 from 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 228

Going ahead to step 8:
If we divide 400 by 228, we get 1 and a remainder of 172.
Use 1 as the next digit of our solution. 
Result so far: 436901.0
Subtract 228 from 400 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 9:
1720 divided by 228 is 7 with a remainder of 124.
Record the quotient 7 as the next digit in the result. 
Result so far: 436901.7
Deduct 1596 from 1720 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 10:
228 can be fit into 1240 5 times, resulting in a remainder of 100.
The next digit of our result is 5. 
Result so far: 436901.75
If we subtract 1140 from 1240, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
If we divide 1000 by 228, we get 4 and a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 436901.754
The remainder is 88 after subtracting 912 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 12:
228 can be fit into 880 3 times, resulting in a remainder of 196.
The number 3 becomes the next digit in our result. 
Result so far: 436901.7543
The remainder is 196 after subtracting 684 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 13:
If we divide 1960 by 228, we get 8 and a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 436901.75438
The remainder is 136 after subtracting 1824 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 14:
The number 228 fits into 1360 5 times, leaving a remainder of 220.
Write down 5 as next digit of the result. 
Result so far: 436901.754385
If we subtract 1140 from 1360, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 15:
228 can be fit into 2200 9 times, resulting in a remainder of 148.
The number 9 becomes the next digit in our result. 
Result so far: 436901.7543859
If we take 2052 away from 2200, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 16:
228 goes into 1480 6 times with a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 436901.75438596
Deduct 1368 from 1480 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

In conclusion, the division gives 436901.75438596 with a balance of 1.12e-07.
