We look at the division of 64238384 by 908 
The aim is to understand the frequency of 908 in 64238384.

On to step 1:
908 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 908

On to step 2:
908 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 908

Advancing to step 3:
The number 908 fits into 642 0 times, leaving a remainder of 642.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 642, we get 642.
Take the next digit (3) from the dividend and append it to 642, then repeat: 6423 / 908

Step 4:
908 goes into 6423 7 times with a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 6356 from 6423 leaves us with 67.
Take the next digit (8) from the dividend and append it to 67, then repeat: 678 / 908

Advancing to step 5:
If we divide 678 by 908, we get 0 and a remainder of 678.
Write down 0 as next digit of the result. 
Result so far: 70.0
Subtracting 0 from 678 leaves us with 678.
Include the next digit (3) from the dividend after 678, then repeat: 6783 / 908

Let's proceed to step 6:
When dividing 6783 by 908, we get 7 with a remainder of 427.
Record the quotient 7 as the next digit in the result. 
Result so far: 707.0
If we subtract 6356 from 6783, we get 427.
Fetch the next digit (8) from the dividend, attach it to 427 and continue: 4278 / 908

Going ahead to step 7:
If we divide 4278 by 908, we get 4 and a remainder of 646.
Write down 4 as next digit of the result. 
Result so far: 7074.0
Deduct 3632 from 4278 and we're left with 646.
Take the next digit (4) from the dividend and append it to 646, then repeat: 6464 / 908

Let's proceed to step 8:
6464 divided by 908 is 7 with a remainder of 108.
Record the quotient 7 as the next digit in the result. 
Result so far: 70747.0
Deduct 6356 from 6464 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 9:
1080 divided by 908 is 1 with a remainder of 172.
Write down 1 as next digit of the result. 
Result so far: 70747.1
Subtract 908 from 1080 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 10:
908 goes into 1720 1 times with a remainder of 812.
Use 1 as the next digit of our solution. 
Result so far: 70747.11
If we take 908 away from 1720, we end up with 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

After the division, we end up with 70747.11 and a remainder of 0.812.
