Let's divide 151933 by 77
The aim is to understand the frequency of 77 in 151933.

Going ahead to step 1:
77 goes into 1 0 times 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 (5) from the dividend after 1, then repeat: 15 / 77

Moving on to step 2:
77 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 77

Let's proceed to step 3:
77 goes into 151 1 times with a remainder of 74.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 77 away from 151, we end up with 74.
Bring next digit (9) of the dividend behind the 74 and repeat the process: 749 / 77

On to step 4:
77 goes into 749 9 times with a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 693 from 749 and we're left with 56.
Bring next digit (3) of the dividend behind the 56 and repeat the process: 563 / 77

Moving on to step 5:
563 divided by 77 is 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 197.0
If we subtract 539 from 563, we get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 77

Let's proceed to step 6:
77 goes into 243 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 1973.0
Subtract 231 from 243 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
77 goes into 120 1 times with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 1973.1
Deduct 77 from 120 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 8:
430 divided by 77 is 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1973.15
If we subtract 385 from 430, 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.

Going ahead to step 9:
The number 77 fits into 450 5 times, leaving a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 1973.155
Subtracting 385 from 450 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 1973.155 with a remainder of 0.0065.
