We look at the division of 23712885 by 906 
The aim is to understand the frequency of 906 in 23712885.

Advancing to step 1:
The number 906 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 906

Going ahead to step 2:
The number 906 fits into 23 0 times, leaving a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 906

Let's proceed to step 3:
The number 906 fits into 237 0 times, leaving a remainder of 237.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 237 and we're left with 237.
Grab the next digit (1) from the dividend, add it to 237, then carry on: 2371 / 906

Step 4:
If we divide 2371 by 906, we get 2 and a remainder of 559.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1812 from 2371 and we're left with 559.
Grab the next digit (2) from the dividend, add it to 559, then carry on: 5592 / 906

Moving on to step 5:
If we divide 5592 by 906, we get 6 and a remainder of 156.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 5436 from 5592 leaves us with 156.
Grab the next digit (8) from the dividend, add it to 156, then carry on: 1568 / 906

Step 6:
If we divide 1568 by 906, we get 1 and a remainder of 662.
Put 1 as the next digit of the answer. 
Result so far: 261.0
If we subtract 906 from 1568, we get 662.
Fetch the next digit (8) from the dividend, attach it to 662 and continue: 6628 / 906

Let's proceed to step 7:
906 can be fit into 6628 7 times, resulting in a remainder of 286.
Write down 7 as next digit of the result. 
Result so far: 2617.0
Deduct 6342 from 6628 and we're left with 286.
Bring next digit (5) of the dividend behind the 286 and repeat the process: 2865 / 906

Step 8:
The number 906 fits into 2865 3 times, leaving a remainder of 147.
Use 3 as the next digit of our solution. 
Result so far: 26173.0
Deduct 2718 from 2865 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 9:
If we divide 1470 by 906, we get 1 and a remainder of 564.
Put 1 as the next digit of the answer. 
Result so far: 26173.1
Deduct 906 from 1470 and we're left with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Step 10:
When dividing 5640 by 906, we get 6 with a remainder of 204.
Write down 6 as next digit of the result. 
Result so far: 26173.16
Subtract 5436 from 5640 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 11:
906 can be fit into 2040 2 times, resulting in a remainder of 228.
Put 2 as the next digit of the answer. 
Result so far: 26173.162
Subtracting 1812 from 2040 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 12:
906 can be fit into 2280 2 times, resulting in a remainder of 468.
Put 2 as the next digit of the answer. 
Result so far: 26173.1622
Subtract 1812 from 2280 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

After the division, we end up with 26173.1622 and a remainder of 0.00468.
