We look at the division of 75141629 by 877 
The aim is to understand the frequency of 877 in 75141629.

Advancing to step 1:
The number 877 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 877

Moving on to step 2:
When dividing 75 by 877, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Take the next digit (1) from the dividend and append it to 75, then repeat: 751 / 877

Step 3:
877 can be fit into 751 0 times, resulting in a remainder of 751.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 751 after subtracting 0 from 751.
Grab the next digit (4) from the dividend, add it to 751, then carry on: 7514 / 877

Advancing to step 4:
The number 877 fits into 7514 8 times, leaving a remainder of 498.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 7016 away from 7514, we end up with 498.
Grab the next digit (1) from the dividend, add it to 498, then carry on: 4981 / 877

Advancing to step 5:
The number 877 fits into 4981 5 times, leaving a remainder of 596.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtract 4385 from 4981 to get 596.
Take the next digit (6) from the dividend and append it to 596, then repeat: 5966 / 877

On to step 6:
877 goes into 5966 6 times with a remainder of 704.
Record the quotient 6 as the next digit in the result. 
Result so far: 856.0
If we subtract 5262 from 5966, we get 704.
Fetch the next digit (2) from the dividend, attach it to 704 and continue: 7042 / 877

Step 7:
877 can be fit into 7042 8 times, resulting in a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 8568.0
If we subtract 7016 from 7042, we get 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 877

Going ahead to step 8:
877 can be fit into 269 0 times, resulting in a remainder of 269.
Use 0 as the next digit of our solution. 
Result so far: 85680.0
If we subtract 0 from 269, we get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Moving on to step 9:
The number 877 fits into 2690 3 times, leaving a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 85680.3
Deduct 2631 from 2690 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 10:
590 divided by 877 is 0 with a remainder of 590.
Write down 0 as next digit of the result. 
Result so far: 85680.3
Subtracting 0 from 590 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

On to step 11:
877 can be fit into 5900 6 times, resulting in a remainder of 638.
The number 6 becomes the next digit in our result. 
Result so far: 85680.306
Subtract 5262 from 5900 to get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Let's proceed to step 12:
When dividing 6380 by 877, we get 7 with a remainder of 241.
The next digit of our result is 7. 
Result so far: 85680.3067
If we subtract 6139 from 6380, we get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

On to step 13:
The number 877 fits into 2410 2 times, leaving a remainder of 656.
Write down 2 as next digit of the result. 
Result so far: 85680.30672
If we take 1754 away from 2410, we end up with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

On to step 14:
877 goes into 6560 7 times with a remainder of 421.
Write down 7 as next digit of the result. 
Result so far: 85680.306727
Subtract 6139 from 6560 to get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Step 15:
When dividing 4210 by 877, we get 4 with a remainder of 702.
Write down 4 as next digit of the result. 
Result so far: 85680.3067274
If we subtract 3508 from 4210, we get 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Let's proceed to step 16:
When dividing 7020 by 877, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 85680.30672748
Subtracting 7016 from 7020 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 85680.30672748 with a balance of 4e-09.
