71196326 ÷ 810 
The aim is to understand the frequency of 810 in 71196326.

Advancing to step 1:
810 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 810

On to step 2:
The number 810 fits into 71 0 times, leaving a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Grab the next digit (1) from the dividend, add it to 71, then carry on: 711 / 810

Advancing to step 3:
When dividing 711 by 810, we get 0 with a remainder of 711.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 711, we end up with 711.
Fetch the next digit (9) from the dividend, attach it to 711 and continue: 7119 / 810

Step 4:
810 can be fit into 7119 8 times, resulting in a remainder of 639.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 6480 from 7119 leaves us with 639.
Take the next digit (6) from the dividend and append it to 639, then repeat: 6396 / 810

Going ahead to step 5:
810 goes into 6396 7 times with a remainder of 726.
Write down 7 as next digit of the result. 
Result so far: 87.0
Deduct 5670 from 6396 and we're left with 726.
Bring next digit (3) of the dividend behind the 726 and repeat the process: 7263 / 810

Going ahead to step 6:
810 goes into 7263 8 times with a remainder of 783.
Use 8 as the next digit of our solution. 
Result so far: 878.0
Deduct 6480 from 7263 and we're left with 783.
Bring next digit (2) of the dividend behind the 783 and repeat the process: 7832 / 810

Step 7:
810 can be fit into 7832 9 times, resulting in a remainder of 542.
The next digit of our result is 9. 
Result so far: 8789.0
If we subtract 7290 from 7832, we get 542.
Take the next digit (6) from the dividend and append it to 542, then repeat: 5426 / 810

Step 8:
When dividing 5426 by 810, we get 6 with a remainder of 566.
Use 6 as the next digit of our solution. 
Result so far: 87896.0
Deduct 4860 from 5426 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Moving on to step 9:
810 goes into 5660 6 times with a remainder of 800.
Write down 6 as next digit of the result. 
Result so far: 87896.6
Subtract 4860 from 5660 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 10:
The number 810 fits into 8000 9 times, leaving a remainder of 710.
Write down 9 as next digit of the result. 
Result so far: 87896.69
Deduct 7290 from 8000 and we're left with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Moving on to step 11:
When dividing 7100 by 810, we get 8 with a remainder of 620.
Use 8 as the next digit of our solution. 
Result so far: 87896.698
The remainder is 620 after subtracting 6480 from 7100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 12:
810 can be fit into 6200 7 times, resulting in a remainder of 530.
Write down 7 as next digit of the result. 
Result so far: 87896.6987
If we take 5670 away from 6200, 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.

Let's proceed to step 13:
The number 810 fits into 5300 6 times, leaving a remainder of 440.
The number 6 becomes the next digit in our result. 
Result so far: 87896.69876
Subtracting 4860 from 5300 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 14:
If we divide 4400 by 810, we get 5 and a remainder of 350.
The next digit of our result is 5. 
Result so far: 87896.698765
If we take 4050 away from 4400, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 15:
810 goes into 3500 4 times with a remainder of 260.
The next digit of our result is 4. 
Result so far: 87896.6987654
If we take 3240 away from 3500, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 16:
2600 divided by 810 is 3 with a remainder of 170.
Put 3 as the next digit of the answer. 
Result so far: 87896.69876543
Subtract 2430 from 2600 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final outcome is 87896.69876543, with a leftover of 1.7e-07.
