We're dividing 50106990 by 766 
The aim is to understand the frequency of 766 in 50106990.

Moving on to step 1:
766 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 766

Moving on to step 2:
If we divide 50 by 766, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 766

Let's proceed to step 3:
766 can be fit into 501 0 times, resulting in a remainder of 501.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 501 and we're left with 501.
Append the next digit (0) from the dividend to 501 and continue with: 5010 / 766

Step 4:
The number 766 fits into 5010 6 times, leaving a remainder of 414.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 4596 from 5010 and we're left with 414.
Take the next digit (6) from the dividend and append it to 414, then repeat: 4146 / 766

Advancing to step 5:
766 can be fit into 4146 5 times, resulting in a remainder of 316.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we subtract 3830 from 4146, we get 316.
Take the next digit (9) from the dividend and append it to 316, then repeat: 3169 / 766

Let's proceed to step 6:
3169 divided by 766 is 4 with a remainder of 105.
Write down 4 as next digit of the result. 
Result so far: 654.0
Deduct 3064 from 3169 and we're left with 105.
Grab the next digit (9) from the dividend, add it to 105, then carry on: 1059 / 766

Step 7:
If we divide 1059 by 766, we get 1 and a remainder of 293.
The next digit of our result is 1. 
Result so far: 6541.0
Deduct 766 from 1059 and we're left with 293.
Append the next digit (0) from the dividend to 293 and continue with: 2930 / 766

Let's proceed to step 8:
If we divide 2930 by 766, we get 3 and a remainder of 632.
Use 3 as the next digit of our solution. 
Result so far: 65413.0
The remainder is 632 after subtracting 2298 from 2930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Let's proceed to step 9:
6320 divided by 766 is 8 with a remainder of 192.
Record the quotient 8 as the next digit in the result. 
Result so far: 65413.8
Deduct 6128 from 6320 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 10:
766 goes into 1920 2 times with a remainder of 388.
Put 2 as the next digit of the answer. 
Result so far: 65413.82
The remainder is 388 after subtracting 1532 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 11:
766 goes into 3880 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 65413.825
Deduct 3830 from 3880 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
500 divided by 766 is 0 with a remainder of 500.
The next digit of our result is 0. 
Result so far: 65413.825
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 13:
5000 divided by 766 is 6 with a remainder of 404.
The number 6 becomes the next digit in our result. 
Result so far: 65413.82506
If we subtract 4596 from 5000, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 14:
If we divide 4040 by 766, we get 5 and a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 65413.825065
The remainder is 210 after subtracting 3830 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 15:
766 can be fit into 2100 2 times, resulting in a remainder of 568.
Write down 2 as next digit of the result. 
Result so far: 65413.8250652
Deduct 1532 from 2100 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Step 16:
The number 766 fits into 5680 7 times, leaving a remainder of 318.
Record the quotient 7 as the next digit in the result. 
Result so far: 65413.82506527
Subtracting 5362 from 5680 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

In conclusion, the division gives 65413.82506527 with a balance of 3.18e-07.
