We're dividing 22337661 by 668 
The aim is to understand the frequency of 668 in 22337661.

Moving on to step 1:
The number 668 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 668

Going ahead to step 2:
668 goes into 22 0 times with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 668

On to step 3:
223 divided by 668 is 0 with a remainder of 223.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 223 to get 223.
Bring next digit (3) of the dividend behind the 223 and repeat the process: 2233 / 668

Going ahead to step 4:
When dividing 2233 by 668, we get 3 with a remainder of 229.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 229 after subtracting 2004 from 2233.
Grab the next digit (7) from the dividend, add it to 229, then carry on: 2297 / 668

Advancing to step 5:
2297 divided by 668 is 3 with a remainder of 293.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtract 2004 from 2297 to get 293.
Append the next digit (6) from the dividend to 293 and continue with: 2936 / 668

Step 6:
2936 divided by 668 is 4 with a remainder of 264.
Use 4 as the next digit of our solution. 
Result so far: 334.0
Subtracting 2672 from 2936 leaves us with 264.
Take the next digit (6) from the dividend and append it to 264, then repeat: 2646 / 668

On to step 7:
668 can be fit into 2646 3 times, resulting in a remainder of 642.
The number 3 becomes the next digit in our result. 
Result so far: 3343.0
Deduct 2004 from 2646 and we're left with 642.
Take the next digit (1) from the dividend and append it to 642, then repeat: 6421 / 668

Let's proceed to step 8:
The number 668 fits into 6421 9 times, leaving a remainder of 409.
Use 9 as the next digit of our solution. 
Result so far: 33439.0
Deduct 6012 from 6421 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Let's proceed to step 9:
The number 668 fits into 4090 6 times, leaving a remainder of 82.
The next digit of our result is 6. 
Result so far: 33439.6
If we take 4008 away from 4090, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 10:
668 can be fit into 820 1 times, resulting in a remainder of 152.
The next digit of our result is 1. 
Result so far: 33439.61
If we take 668 away from 820, 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.

Step 11:
If we divide 1520 by 668, we get 2 and a remainder of 184.
Record the quotient 2 as the next digit in the result. 
Result so far: 33439.612
The remainder is 184 after subtracting 1336 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 12:
The number 668 fits into 1840 2 times, leaving a remainder of 504.
Put 2 as the next digit of the answer. 
Result so far: 33439.6122
If we subtract 1336 from 1840, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

The final outcome is 33439.6122, with a leftover of 0.00504.
