We're dividing 41370585 by 877 
The aim is to understand the frequency of 877 in 41370585.

Let's proceed to step 1:
The number 877 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 877

Step 2:
877 goes into 41 0 times with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Take the next digit (3) from the dividend and append it to 41, then repeat: 413 / 877

Going ahead to step 3:
The number 877 fits into 413 0 times, leaving a remainder of 413.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 413 and we're left with 413.
Fetch the next digit (7) from the dividend, attach it to 413 and continue: 4137 / 877

Step 4:
4137 divided by 877 is 4 with a remainder of 629.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 3508 from 4137, we get 629.
Take the next digit (0) from the dividend and append it to 629, then repeat: 6290 / 877

Advancing to step 5:
The number 877 fits into 6290 7 times, leaving a remainder of 151.
The next digit of our result is 7. 
Result so far: 47.0
If we take 6139 away from 6290, we end up with 151.
Grab the next digit (5) from the dividend, add it to 151, then carry on: 1515 / 877

Let's proceed to step 6:
877 goes into 1515 1 times with a remainder of 638.
The next digit of our result is 1. 
Result so far: 471.0
Subtracting 877 from 1515 leaves us with 638.
Take the next digit (8) from the dividend and append it to 638, then repeat: 6388 / 877

Let's proceed to step 7:
877 can be fit into 6388 7 times, resulting in a remainder of 249.
Use 7 as the next digit of our solution. 
Result so far: 4717.0
If we take 6139 away from 6388, we end up with 249.
Include the next digit (5) from the dividend after 249, then repeat: 2495 / 877

On to step 8:
2495 divided by 877 is 2 with a remainder of 741.
Put 2 as the next digit of the answer. 
Result so far: 47172.0
Deduct 1754 from 2495 and we're left with 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Going ahead to step 9:
If we divide 7410 by 877, we get 8 and a remainder of 394.
Use 8 as the next digit of our solution. 
Result so far: 47172.8
The remainder is 394 after subtracting 7016 from 7410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Advancing to step 10:
The number 877 fits into 3940 4 times, leaving a remainder of 432.
Record the quotient 4 as the next digit in the result. 
Result so far: 47172.84
Subtract 3508 from 3940 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 11:
If we divide 4320 by 877, we get 4 and a remainder of 812.
The number 4 becomes the next digit in our result. 
Result so far: 47172.844
Subtracting 3508 from 4320 leaves us with 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

After the division, we end up with 47172.844 and a remainder of 0.0812.
