We're dividing 68471149 by 810 
The aim is to understand the frequency of 810 in 68471149.

Let's proceed to step 1:
The number 810 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 810

Moving on to step 2:
68 divided by 810 is 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Bring next digit (4) of the dividend behind the 68 and repeat the process: 684 / 810

Advancing to step 3:
The number 810 fits into 684 0 times, leaving a remainder of 684.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 684 after subtracting 0 from 684.
Include the next digit (7) from the dividend after 684, then repeat: 6847 / 810

Let's proceed to step 4:
The number 810 fits into 6847 8 times, leaving a remainder of 367.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 367 after subtracting 6480 from 6847.
Take the next digit (1) from the dividend and append it to 367, then repeat: 3671 / 810

Step 5:
The number 810 fits into 3671 4 times, leaving a remainder of 431.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtract 3240 from 3671 to get 431.
Include the next digit (1) from the dividend after 431, then repeat: 4311 / 810

Let's proceed to step 6:
4311 divided by 810 is 5 with a remainder of 261.
The next digit of our result is 5. 
Result so far: 845.0
Subtract 4050 from 4311 to get 261.
Append the next digit (4) from the dividend to 261 and continue with: 2614 / 810

Going ahead to step 7:
810 goes into 2614 3 times with a remainder of 184.
The number 3 becomes the next digit in our result. 
Result so far: 8453.0
The remainder is 184 after subtracting 2430 from 2614.
Grab the next digit (9) from the dividend, add it to 184, then carry on: 1849 / 810

On to step 8:
If we divide 1849 by 810, we get 2 and a remainder of 229.
Use 2 as the next digit of our solution. 
Result so far: 84532.0
If we subtract 1620 from 1849, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Advancing to step 9:
810 can be fit into 2290 2 times, resulting in a remainder of 670.
Use 2 as the next digit of our solution. 
Result so far: 84532.2
If we subtract 1620 from 2290, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 10:
When dividing 6700 by 810, we get 8 with a remainder of 220.
The next digit of our result is 8. 
Result so far: 84532.28
If we subtract 6480 from 6700, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
If we divide 2200 by 810, we get 2 and a remainder of 580.
Record the quotient 2 as the next digit in the result. 
Result so far: 84532.282
The remainder is 580 after subtracting 1620 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 12:
If we divide 5800 by 810, we get 7 and a remainder of 130.
Use 7 as the next digit of our solution. 
Result so far: 84532.2827
Subtracting 5670 from 5800 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 13:
The number 810 fits into 1300 1 times, leaving a remainder of 490.
Use 1 as the next digit of our solution. 
Result so far: 84532.28271
Subtracting 810 from 1300 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 14:
810 can be fit into 4900 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 84532.282716
The remainder is 40 after subtracting 4860 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
The number 810 fits into 400 0 times, leaving a remainder of 400.
The next digit of our result is 0. 
Result so far: 84532.282716
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 16:
When dividing 4000 by 810, we get 4 with a remainder of 760.
Write down 4 as next digit of the result. 
Result so far: 84532.28271604
Deduct 3240 from 4000 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

The quotient of the division is 84532.28271604, and the remainder is 7.6e-07.
