We look at the division of 3741921 by 222 
The aim is to understand the frequency of 222 in 3741921.

Advancing to step 1:
3 divided by 222 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 222

Step 2:
222 goes into 37 0 times with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Take the next digit (4) from the dividend and append it to 37, then repeat: 374 / 222

Advancing to step 3:
The number 222 fits into 374 1 times, leaving a remainder of 152.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 152 after subtracting 222 from 374.
Bring next digit (1) of the dividend behind the 152 and repeat the process: 1521 / 222

Step 4:
If we divide 1521 by 222, we get 6 and a remainder of 189.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 1332 from 1521 leaves us with 189.
Append the next digit (9) from the dividend to 189 and continue with: 1899 / 222

Moving on to step 5:
When dividing 1899 by 222, we get 8 with a remainder of 123.
Use 8 as the next digit of our solution. 
Result so far: 168.0
If we take 1776 away from 1899, we end up with 123.
Take the next digit (2) from the dividend and append it to 123, then repeat: 1232 / 222

On to step 6:
When dividing 1232 by 222, we get 5 with a remainder of 122.
The next digit of our result is 5. 
Result so far: 1685.0
Deduct 1110 from 1232 and we're left with 122.
Append the next digit (1) from the dividend to 122 and continue with: 1221 / 222

Going ahead to step 7:
If we divide 1221 by 222, we get 5 and a remainder of 111.
Put 5 as the next digit of the answer. 
Result so far: 16855.0
If we subtract 1110 from 1221, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 8:
222 can be fit into 1110 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 16855.5
Subtracting 1110 from 1110 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
When dividing 0 by 222, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16855.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
When dividing 0 by 222, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16855.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 16855.5 and a remainder of 0.0.
