We look at the division of 73778780 by 222 
The aim is to understand the frequency of 222 in 73778780.

On to step 1:
7 divided by 222 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 222

Advancing to step 2:
222 goes into 73 0 times with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 222

Moving on to step 3:
222 can be fit into 737 3 times, resulting in a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 666 from 737, we get 71.
Take the next digit (7) from the dividend and append it to 71, then repeat: 717 / 222

Let's proceed to step 4:
When dividing 717 by 222, we get 3 with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we subtract 666 from 717, we get 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 222

On to step 5:
222 can be fit into 518 2 times, resulting in a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 332.0
Subtracting 444 from 518 leaves us with 74.
Take the next digit (7) from the dividend and append it to 74, then repeat: 747 / 222

Moving on to step 6:
The number 222 fits into 747 3 times, leaving a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 3323.0
If we subtract 666 from 747, we get 81.
Grab the next digit (8) from the dividend, add it to 81, then carry on: 818 / 222

Advancing to step 7:
If we divide 818 by 222, we get 3 and a remainder of 152.
Put 3 as the next digit of the answer. 
Result so far: 33233.0
Subtract 666 from 818 to get 152.
Append the next digit (0) from the dividend to 152 and continue with: 1520 / 222

On to step 8:
1520 divided by 222 is 6 with a remainder of 188.
Use 6 as the next digit of our solution. 
Result so far: 332336.0
Subtracting 1332 from 1520 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 9:
The number 222 fits into 1880 8 times, leaving a remainder of 104.
Use 8 as the next digit of our solution. 
Result so far: 332336.8
If we take 1776 away from 1880, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 10:
222 goes into 1040 4 times with a remainder of 152.
The next digit of our result is 4. 
Result so far: 332336.84
Subtracting 888 from 1040 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 11:
222 can be fit into 1520 6 times, resulting in a remainder of 188.
Put 6 as the next digit of the answer. 
Result so far: 332336.846
If we subtract 1332 from 1520, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 12:
When dividing 1880 by 222, we get 8 with a remainder of 104.
The next digit of our result is 8. 
Result so far: 332336.8468
Deduct 1776 from 1880 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 13:
The number 222 fits into 1040 4 times, leaving a remainder of 152.
Record the quotient 4 as the next digit in the result. 
Result so far: 332336.84684
The remainder is 152 after subtracting 888 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 14:
222 can be fit into 1520 6 times, resulting in a remainder of 188.
Put 6 as the next digit of the answer. 
Result so far: 332336.846846
If we take 1332 away from 1520, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 15:
222 can be fit into 1880 8 times, resulting in a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 332336.8468468
The remainder is 104 after subtracting 1776 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 16:
If we divide 1040 by 222, we get 4 and a remainder of 152.
The number 4 becomes the next digit in our result. 
Result so far: 332336.84684684
If we take 888 away from 1040, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

After the division, we end up with 332336.84684684 and a remainder of 1.52e-07.
