72189384 divided by 228 
The aim is to understand the frequency of 228 in 72189384.

On to step 1:
228 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 228

Let's proceed to step 2:
When dividing 72 by 228, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 228

On to step 3:
228 goes into 721 3 times with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 684 from 721 to get 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 228

Step 4:
If we divide 378 by 228, we get 1 and a remainder of 150.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Deduct 228 from 378 and we're left with 150.
Fetch the next digit (9) from the dividend, attach it to 150 and continue: 1509 / 228

Moving on to step 5:
When dividing 1509 by 228, we get 6 with a remainder of 141.
Put 6 as the next digit of the answer. 
Result so far: 316.0
Subtract 1368 from 1509 to get 141.
Append the next digit (3) from the dividend to 141 and continue with: 1413 / 228

Moving on to step 6:
1413 divided by 228 is 6 with a remainder of 45.
The next digit of our result is 6. 
Result so far: 3166.0
Subtracting 1368 from 1413 leaves us with 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 228

Advancing to step 7:
When dividing 458 by 228, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 31662.0
Deduct 456 from 458 and we're left with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 228

Advancing to step 8:
When dividing 24 by 228, we get 0 with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 316620.0
Subtracting 0 from 24 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
If we divide 240 by 228, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 316620.1
Deduct 228 from 240 and we're left 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.

Moving on to step 10:
If we divide 120 by 228, we get 0 and a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 316620.1
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.

Moving on to step 11:
1200 divided by 228 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 316620.105
If we take 1140 away from 1200, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
The number 228 fits into 600 2 times, leaving a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 316620.1052
If we subtract 456 from 600, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 13:
When dividing 1440 by 228, we get 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 316620.10526
If we subtract 1368 from 1440, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
720 divided by 228 is 3 with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 316620.105263
If we take 684 away from 720, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 15:
228 can be fit into 360 1 times, resulting in a remainder of 132.
The next digit of our result is 1. 
Result so far: 316620.1052631
If we take 228 away from 360, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 16:
228 goes into 1320 5 times with a remainder of 180.
Use 5 as the next digit of our solution. 
Result so far: 316620.10526315
Deduct 1140 from 1320 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 316620.10526315, with a leftover of 1.8e-07.
