223408 divided by 37 
The aim is to understand the frequency of 37 in 223408.

Step 1:
2 divided by 37 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
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 / 37

Let's proceed to step 2:
If we divide 22 by 37, we get 0 and a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 37

Going ahead to step 3:
223 divided by 37 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 222 from 223 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 37

Moving on to step 4:
37 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 60.0
If we subtract 0 from 14, we get 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 37

Moving on to step 5:
37 can be fit into 140 3 times, resulting in a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 603.0
Subtract 111 from 140 to get 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 37

On to step 6:
37 can be fit into 298 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 6038.0
The remainder is 2 after subtracting 296 from 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
37 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 6038.0
Deduct 0 from 20 and we're left 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.

Step 8:
When dividing 200 by 37, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 6038.05
If we take 185 away from 200, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
When dividing 150 by 37, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 6038.054
If we subtract 148 from 150, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
20 divided by 37 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 6038.054
If we take 0 away from 20, we end up 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.

On to step 11:
37 goes into 200 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 6038.05405
Subtract 185 from 200 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
37 can be fit into 150 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 6038.054054
The remainder is 2 after subtracting 148 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
37 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 6038.054054
If we take 0 away from 20, we end up 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.

Advancing to step 14:
When dividing 200 by 37, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 6038.05405405
Deduct 185 from 200 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 6038.05405405 with a remainder of 1.5e-08.
