We look at the division of 47752303 by 810 
The aim is to understand the frequency of 810 in 47752303.

Moving on to step 1:
810 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 810

Going ahead to step 2:
810 goes into 47 0 times with a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 47 after subtracting 0 from 47.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 810

Step 3:
If we divide 477 by 810, we get 0 and a remainder of 477.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 477 after subtracting 0 from 477.
Include the next digit (5) from the dividend after 477, then repeat: 4775 / 810

Advancing to step 4:
The number 810 fits into 4775 5 times, leaving a remainder of 725.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4050 from 4775 to get 725.
Take the next digit (2) from the dividend and append it to 725, then repeat: 7252 / 810

Let's proceed to step 5:
The number 810 fits into 7252 8 times, leaving a remainder of 772.
Use 8 as the next digit of our solution. 
Result so far: 58.0
The remainder is 772 after subtracting 6480 from 7252.
Append the next digit (3) from the dividend to 772 and continue with: 7723 / 810

Advancing to step 6:
When dividing 7723 by 810, we get 9 with a remainder of 433.
The next digit of our result is 9. 
Result so far: 589.0
If we subtract 7290 from 7723, we get 433.
Include the next digit (0) from the dividend after 433, then repeat: 4330 / 810

Going ahead to step 7:
810 goes into 4330 5 times with a remainder of 280.
Put 5 as the next digit of the answer. 
Result so far: 5895.0
Deduct 4050 from 4330 and we're left with 280.
Fetch the next digit (3) from the dividend, attach it to 280 and continue: 2803 / 810

On to step 8:
When dividing 2803 by 810, we get 3 with a remainder of 373.
Record the quotient 3 as the next digit in the result. 
Result so far: 58953.0
The remainder is 373 after subtracting 2430 from 2803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 9:
If we divide 3730 by 810, we get 4 and a remainder of 490.
Record the quotient 4 as the next digit in the result. 
Result so far: 58953.4
The remainder is 490 after subtracting 3240 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 10:
If we divide 4900 by 810, we get 6 and a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 58953.46
Subtract 4860 from 4900 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
810 goes into 400 0 times with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 58953.46
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
If we divide 4000 by 810, we get 4 and a remainder of 760.
Put 4 as the next digit of the answer. 
Result so far: 58953.4604
If we subtract 3240 from 4000, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 13:
810 can be fit into 7600 9 times, resulting in a remainder of 310.
Put 9 as the next digit of the answer. 
Result so far: 58953.46049
The remainder is 310 after subtracting 7290 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 14:
3100 divided by 810 is 3 with a remainder of 670.
Write down 3 as next digit of the result. 
Result so far: 58953.460493
The remainder is 670 after subtracting 2430 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 15:
When dividing 6700 by 810, we get 8 with a remainder of 220.
The next digit of our result is 8. 
Result so far: 58953.4604938
Deduct 6480 from 6700 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 16:
When dividing 2200 by 810, we get 2 with a remainder of 580.
Record the quotient 2 as the next digit in the result. 
Result so far: 58953.46049382
Deduct 1620 from 2200 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

The final outcome is 58953.46049382, with a leftover of 5.8e-07.
