We look at the division of 3720770 by 923 
The aim is to understand the frequency of 923 in 3720770.

Let's proceed to step 1:
If we divide 3 by 923, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 923

Moving on to step 2:
When dividing 37 by 923, we get 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 923

Going ahead to step 3:
When dividing 372 by 923, we get 0 with a remainder of 372.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 372 to get 372.
Fetch the next digit (0) from the dividend, attach it to 372 and continue: 3720 / 923

Moving on to step 4:
923 goes into 3720 4 times with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 28 after subtracting 3692 from 3720.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 923

Step 5:
287 divided by 923 is 0 with a remainder of 287.
The next digit of our result is 0. 
Result so far: 40.0
The remainder is 287 after subtracting 0 from 287.
Take the next digit (7) from the dividend and append it to 287, then repeat: 2877 / 923

Let's proceed to step 6:
When dividing 2877 by 923, we get 3 with a remainder of 108.
Write down 3 as next digit of the result. 
Result so far: 403.0
The remainder is 108 after subtracting 2769 from 2877.
Bring next digit (0) of the dividend behind the 108 and repeat the process: 1080 / 923

Step 7:
The number 923 fits into 1080 1 times, leaving a remainder of 157.
The number 1 becomes the next digit in our result. 
Result so far: 4031.0
If we take 923 away from 1080, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 8:
1570 divided by 923 is 1 with a remainder of 647.
Put 1 as the next digit of the answer. 
Result so far: 4031.1
Deduct 923 from 1570 and we're left with 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Step 9:
6470 divided by 923 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 4031.17
If we take 6461 away from 6470, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
923 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 4031.17
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 11:
When dividing 900 by 923, we get 0 with a remainder of 900.
The next digit of our result is 0. 
Result so far: 4031.17
Deduct 0 from 900 and we're left with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

The final result is 4031.17 with a remainder of 0.009.
