We divide 37659 by 77
The aim is to understand the frequency of 77 in 37659.

Step 1:
The number 77 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 77

Step 2:
When dividing 37 by 77, we get 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 77

On to step 3:
77 can be fit into 376 4 times, resulting in a remainder of 68.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 308 from 376 leaves us with 68.
Append the next digit (5) from the dividend to 68 and continue with: 685 / 77

Going ahead to step 4:
If we divide 685 by 77, we get 8 and a remainder of 69.
Put 8 as the next digit of the answer. 
Result so far: 48.0
The remainder is 69 after subtracting 616 from 685.
Include the next digit (9) from the dividend after 69, then repeat: 699 / 77

Let's proceed to step 5:
699 divided by 77 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 489.0
The remainder is 6 after subtracting 693 from 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 6:
77 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 489.0
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 7:
If we divide 600 by 77, we get 7 and a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 489.07
If we take 539 away from 600, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 8:
If we divide 610 by 77, we get 7 and a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 489.077
Subtract 539 from 610 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The quotient of the division is 489.077, and the remainder is 0.0071.
