We're dividing 21900223 by 908 
The aim is to understand the frequency of 908 in 21900223.

Let's proceed to step 1:
908 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 908

Advancing to step 2:
If we divide 21 by 908, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 908

Let's proceed to step 3:
The number 908 fits into 219 0 times, leaving a remainder of 219.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 219 after subtracting 0 from 219.
Include the next digit (0) from the dividend after 219, then repeat: 2190 / 908

Advancing to step 4:
2190 divided by 908 is 2 with a remainder of 374.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1816 away from 2190, we end up with 374.
Take the next digit (0) from the dividend and append it to 374, then repeat: 3740 / 908

Moving on to step 5:
908 goes into 3740 4 times with a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Deduct 3632 from 3740 and we're left with 108.
Bring next digit (2) of the dividend behind the 108 and repeat the process: 1082 / 908

Advancing to step 6:
When dividing 1082 by 908, we get 1 with a remainder of 174.
Use 1 as the next digit of our solution. 
Result so far: 241.0
If we take 908 away from 1082, we end up with 174.
Bring next digit (2) of the dividend behind the 174 and repeat the process: 1742 / 908

Moving on to step 7:
908 can be fit into 1742 1 times, resulting in a remainder of 834.
The next digit of our result is 1. 
Result so far: 2411.0
Subtract 908 from 1742 to get 834.
Fetch the next digit (3) from the dividend, attach it to 834 and continue: 8343 / 908

Advancing to step 8:
The number 908 fits into 8343 9 times, leaving a remainder of 171.
The next digit of our result is 9. 
Result so far: 24119.0
The remainder is 171 after subtracting 8172 from 8343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 9:
The number 908 fits into 1710 1 times, leaving a remainder of 802.
The number 1 becomes the next digit in our result. 
Result so far: 24119.1
Subtract 908 from 1710 to get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Advancing to step 10:
8020 divided by 908 is 8 with a remainder of 756.
Write down 8 as next digit of the result. 
Result so far: 24119.18
Subtract 7264 from 8020 to get 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Step 11:
908 can be fit into 7560 8 times, resulting in a remainder of 296.
The number 8 becomes the next digit in our result. 
Result so far: 24119.188
If we take 7264 away from 7560, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Our division results in 24119.188 with a remaining 0.0296.
