We look at the division of 83346339 by 877 
The aim is to understand the frequency of 877 in 83346339.

Advancing to step 1:
When dividing 8 by 877, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 877

Moving on to step 2:
The number 877 fits into 83 0 times, leaving a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Take the next digit (3) from the dividend and append it to 83, then repeat: 833 / 877

Advancing to step 3:
877 goes into 833 0 times with a remainder of 833.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 833 and we're left with 833.
Fetch the next digit (4) from the dividend, attach it to 833 and continue: 8334 / 877

Moving on to step 4:
When dividing 8334 by 877, we get 9 with a remainder of 441.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 7893 from 8334 to get 441.
Fetch the next digit (6) from the dividend, attach it to 441 and continue: 4416 / 877

Moving on to step 5:
877 goes into 4416 5 times with a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Deduct 4385 from 4416 and we're left with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 877

Moving on to step 6:
313 divided by 877 is 0 with a remainder of 313.
Use 0 as the next digit of our solution. 
Result so far: 950.0
If we take 0 away from 313, we end up with 313.
Append the next digit (3) from the dividend to 313 and continue with: 3133 / 877

Advancing to step 7:
3133 divided by 877 is 3 with a remainder of 502.
The number 3 becomes the next digit in our result. 
Result so far: 9503.0
Subtract 2631 from 3133 to get 502.
Append the next digit (9) from the dividend to 502 and continue with: 5029 / 877

Moving on to step 8:
877 can be fit into 5029 5 times, resulting in a remainder of 644.
Use 5 as the next digit of our solution. 
Result so far: 95035.0
If we take 4385 away from 5029, we end up with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Step 9:
877 can be fit into 6440 7 times, resulting in a remainder of 301.
Use 7 as the next digit of our solution. 
Result so far: 95035.7
Subtract 6139 from 6440 to get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 10:
877 goes into 3010 3 times with a remainder of 379.
The next digit of our result is 3. 
Result so far: 95035.73
Deduct 2631 from 3010 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

On to step 11:
3790 divided by 877 is 4 with a remainder of 282.
Use 4 as the next digit of our solution. 
Result so far: 95035.734
If we subtract 3508 from 3790, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 12:
2820 divided by 877 is 3 with a remainder of 189.
Record the quotient 3 as the next digit in the result. 
Result so far: 95035.7343
If we take 2631 away from 2820, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Advancing to step 13:
877 goes into 1890 2 times with a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 95035.73432
If we take 1754 away from 1890, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 14:
When dividing 1360 by 877, we get 1 with a remainder of 483.
Put 1 as the next digit of the answer. 
Result so far: 95035.734321
If we take 877 away from 1360, we end up with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Let's proceed to step 15:
The number 877 fits into 4830 5 times, leaving a remainder of 445.
The number 5 becomes the next digit in our result. 
Result so far: 95035.7343215
Subtracting 4385 from 4830 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 16:
4450 divided by 877 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 95035.73432155
Subtracting 4385 from 4450 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 95035.73432155 with a remainder of 6.5e-08.
