We look at the division of 22378070 by 669 
The aim is to understand the frequency of 669 in 22378070.

Going ahead to step 1:
669 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 669

Moving on to step 2:
When dividing 22 by 669, we get 0 with a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Append the next digit (3) from the dividend to 22 and continue with: 223 / 669

Step 3:
223 divided by 669 is 0 with a remainder of 223.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 223 after subtracting 0 from 223.
Append the next digit (7) from the dividend to 223 and continue with: 2237 / 669

Advancing to step 4:
The number 669 fits into 2237 3 times, leaving a remainder of 230.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 2007 away from 2237, we end up with 230.
Append the next digit (8) from the dividend to 230 and continue with: 2308 / 669

On to step 5:
When dividing 2308 by 669, we get 3 with a remainder of 301.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 2007 from 2308 and we're left with 301.
Fetch the next digit (0) from the dividend, attach it to 301 and continue: 3010 / 669

Let's proceed to step 6:
669 goes into 3010 4 times with a remainder of 334.
Write down 4 as next digit of the result. 
Result so far: 334.0
If we take 2676 away from 3010, we end up with 334.
Include the next digit (7) from the dividend after 334, then repeat: 3347 / 669

Advancing to step 7:
669 goes into 3347 5 times with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 3345.0
Deduct 3345 from 3347 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 669

Let's proceed to step 8:
20 divided by 669 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 33450.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 669 is 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 33450.0
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 10:
669 can be fit into 2000 2 times, resulting in a remainder of 662.
Use 2 as the next digit of our solution. 
Result so far: 33450.02
Deduct 1338 from 2000 and we're left with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Let's proceed to step 11:
When dividing 6620 by 669, we get 9 with a remainder of 599.
Put 9 as the next digit of the answer. 
Result so far: 33450.029
If we take 6021 away from 6620, we end up with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Moving on to step 12:
5990 divided by 669 is 8 with a remainder of 638.
Use 8 as the next digit of our solution. 
Result so far: 33450.0298
If we take 5352 away from 5990, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Step 13:
The number 669 fits into 6380 9 times, leaving a remainder of 359.
The number 9 becomes the next digit in our result. 
Result so far: 33450.02989
The remainder is 359 after subtracting 6021 from 6380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 14:
When dividing 3590 by 669, we get 5 with a remainder of 245.
The number 5 becomes the next digit in our result. 
Result so far: 33450.029895
Deduct 3345 from 3590 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 15:
The number 669 fits into 2450 3 times, leaving a remainder of 443.
Put 3 as the next digit of the answer. 
Result so far: 33450.0298953
The remainder is 443 after subtracting 2007 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Moving on to step 16:
4430 divided by 669 is 6 with a remainder of 416.
Put 6 as the next digit of the answer. 
Result so far: 33450.02989536
Deduct 4014 from 4430 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The quotient of the division is 33450.02989536, and the remainder is 4.16e-07.
