We're dividing 3843620 by 923 
The aim is to understand the frequency of 923 in 3843620.

On to step 1:
923 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 923

Step 2:
If we divide 38 by 923, we get 0 and a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 923

Let's proceed to step 3:
If we divide 384 by 923, we get 0 and a remainder of 384.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 384 after subtracting 0 from 384.
Grab the next digit (3) from the dividend, add it to 384, then carry on: 3843 / 923

Step 4:
923 goes into 3843 4 times with a remainder of 151.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3692 away from 3843, we end up with 151.
Bring next digit (6) of the dividend behind the 151 and repeat the process: 1516 / 923

On to step 5:
The number 923 fits into 1516 1 times, leaving a remainder of 593.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
The remainder is 593 after subtracting 923 from 1516.
Bring next digit (2) of the dividend behind the 593 and repeat the process: 5932 / 923

Moving on to step 6:
When dividing 5932 by 923, we get 6 with a remainder of 394.
Use 6 as the next digit of our solution. 
Result so far: 416.0
Subtract 5538 from 5932 to get 394.
Include the next digit (0) from the dividend after 394, then repeat: 3940 / 923

Let's proceed to step 7:
923 can be fit into 3940 4 times, resulting in a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 4164.0
Deduct 3692 from 3940 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 8:
923 goes into 2480 2 times with a remainder of 634.
The number 2 becomes the next digit in our result. 
Result so far: 4164.2
If we take 1846 away from 2480, we end up with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Advancing to step 9:
923 can be fit into 6340 6 times, resulting in a remainder of 802.
Use 6 as the next digit of our solution. 
Result so far: 4164.26
The remainder is 802 after subtracting 5538 from 6340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

On to step 10:
When dividing 8020 by 923, we get 8 with a remainder of 636.
The number 8 becomes the next digit in our result. 
Result so far: 4164.268
If we subtract 7384 from 8020, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 11:
When dividing 6360 by 923, we get 6 with a remainder of 822.
Record the quotient 6 as the next digit in the result. 
Result so far: 4164.2686
Subtract 5538 from 6360 to get 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Going ahead to step 12:
When dividing 8220 by 923, we get 8 with a remainder of 836.
Record the quotient 8 as the next digit in the result. 
Result so far: 4164.26868
If we subtract 7384 from 8220, we get 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Step 13:
923 goes into 8360 9 times with a remainder of 53.
The next digit of our result is 9. 
Result so far: 4164.268689
Subtracting 8307 from 8360 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 14:
When dividing 530 by 923, we get 0 with a remainder of 530.
Write down 0 as next digit of the result. 
Result so far: 4164.268689
If we take 0 away from 530, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 15:
923 can be fit into 5300 5 times, resulting in a remainder of 685.
The next digit of our result is 5. 
Result so far: 4164.26868905
Subtract 4615 from 5300 to get 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

The quotient of the division is 4164.26868905, and the remainder is 6.85e-07.
