Let's divide 38029890 by 810
The aim is to understand the frequency of 810 in 38029890.

Moving on to step 1:
When dividing 3 by 810, we get 0 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.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 810

Let's proceed to step 2:
When dividing 38 by 810, we get 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 810

Step 3:
380 divided by 810 is 0 with a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 380 to get 380.
Bring next digit (2) of the dividend behind the 380 and repeat the process: 3802 / 810

Advancing to step 4:
810 can be fit into 3802 4 times, resulting in a remainder of 562.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 562 after subtracting 3240 from 3802.
Include the next digit (9) from the dividend after 562, then repeat: 5629 / 810

Moving on to step 5:
810 goes into 5629 6 times with a remainder of 769.
The next digit of our result is 6. 
Result so far: 46.0
Subtract 4860 from 5629 to get 769.
Include the next digit (8) from the dividend after 769, then repeat: 7698 / 810

Going ahead to step 6:
If we divide 7698 by 810, we get 9 and a remainder of 408.
Record the quotient 9 as the next digit in the result. 
Result so far: 469.0
If we take 7290 away from 7698, we end up with 408.
Include the next digit (9) from the dividend after 408, then repeat: 4089 / 810

Step 7:
810 goes into 4089 5 times with a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 4695.0
The remainder is 39 after subtracting 4050 from 4089.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 810

Moving on to step 8:
810 can be fit into 390 0 times, resulting in a remainder of 390.
Write down 0 as next digit of the result. 
Result so far: 46950.0
If we take 0 away from 390, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 9:
If we divide 3900 by 810, we get 4 and a remainder of 660.
Put 4 as the next digit of the answer. 
Result so far: 46950.4
Subtract 3240 from 3900 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 10:
When dividing 6600 by 810, we get 8 with a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 46950.48
If we take 6480 away from 6600, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 11:
1200 divided by 810 is 1 with a remainder of 390.
Put 1 as the next digit of the answer. 
Result so far: 46950.481
Deduct 810 from 1200 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 12:
If we divide 3900 by 810, we get 4 and a remainder of 660.
Put 4 as the next digit of the answer. 
Result so far: 46950.4814
The remainder is 660 after subtracting 3240 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 13:
6600 divided by 810 is 8 with a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 46950.48148
Subtract 6480 from 6600 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 14:
810 goes into 1200 1 times with a remainder of 390.
Write down 1 as next digit of the result. 
Result so far: 46950.481481
If we take 810 away from 1200, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 15:
If we divide 3900 by 810, we get 4 and a remainder of 660.
Put 4 as the next digit of the answer. 
Result so far: 46950.4814814
If we take 3240 away from 3900, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 16:
When dividing 6600 by 810, we get 8 with a remainder of 120.
Record the quotient 8 as the next digit in the result. 
Result so far: 46950.48148148
If we take 6480 away from 6600, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 46950.48148148 with a remaining 1.2e-07.
