We're dividing 17274712 by 877 
The aim is to understand the frequency of 877 in 17274712.

Step 1:
When dividing 1 by 877, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 877

Step 2:
When dividing 17 by 877, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 877

On to step 3:
If we divide 172 by 877, we get 0 and a remainder of 172.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 172 to get 172.
Take the next digit (7) from the dividend and append it to 172, then repeat: 1727 / 877

Advancing to step 4:
When dividing 1727 by 877, we get 1 with a remainder of 850.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 877 from 1727 leaves us with 850.
Bring next digit (4) of the dividend behind the 850 and repeat the process: 8504 / 877

On to step 5:
If we divide 8504 by 877, we get 9 and a remainder of 611.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 611 after subtracting 7893 from 8504.
Include the next digit (7) from the dividend after 611, then repeat: 6117 / 877

Step 6:
6117 divided by 877 is 6 with a remainder of 855.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
If we take 5262 away from 6117, we end up with 855.
Include the next digit (1) from the dividend after 855, then repeat: 8551 / 877

Going ahead to step 7:
877 can be fit into 8551 9 times, resulting in a remainder of 658.
Put 9 as the next digit of the answer. 
Result so far: 1969.0
The remainder is 658 after subtracting 7893 from 8551.
Grab the next digit (2) from the dividend, add it to 658, then carry on: 6582 / 877

Step 8:
6582 divided by 877 is 7 with a remainder of 443.
Use 7 as the next digit of our solution. 
Result so far: 19697.0
If we subtract 6139 from 6582, we get 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Advancing to step 9:
877 goes into 4430 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 19697.5
If we subtract 4385 from 4430, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
877 goes into 450 0 times with a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 19697.5
Subtracting 0 from 450 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 11:
4500 divided by 877 is 5 with a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 19697.505
If we take 4385 away from 4500, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 12:
877 can be fit into 1150 1 times, resulting in a remainder of 273.
Put 1 as the next digit of the answer. 
Result so far: 19697.5051
Subtract 877 from 1150 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 13:
2730 divided by 877 is 3 with a remainder of 99.
Use 3 as the next digit of our solution. 
Result so far: 19697.50513
Deduct 2631 from 2730 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 14:
990 divided by 877 is 1 with a remainder of 113.
Write down 1 as next digit of the result. 
Result so far: 19697.505131
If we subtract 877 from 990, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 15:
1130 divided by 877 is 1 with a remainder of 253.
Put 1 as the next digit of the answer. 
Result so far: 19697.5051311
Deduct 877 from 1130 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

The final result is 19697.5051311 with a remainder of 2.53e-06.
