602366 ÷ 77 
The aim is to understand the frequency of 77 in 602366.

Step 1:
If we divide 6 by 77, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 77

Going ahead to step 2:
The number 77 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Include the next digit (2) from the dividend after 60, then repeat: 602 / 77

Step 3:
77 goes into 602 7 times with a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 539 from 602, we get 63.
Append the next digit (3) from the dividend to 63 and continue with: 633 / 77

On to step 4:
If we divide 633 by 77, we get 8 and a remainder of 17.
The next digit of our result is 8. 
Result so far: 78.0
Subtracting 616 from 633 leaves us with 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 77

Let's proceed to step 5:
The number 77 fits into 176 2 times, leaving a remainder of 22.
The next digit of our result is 2. 
Result so far: 782.0
Deduct 154 from 176 and we're left with 22.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 77

On to step 6:
77 goes into 226 2 times with a remainder of 72.
The next digit of our result is 2. 
Result so far: 7822.0
Deduct 154 from 226 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 7:
77 can be fit into 720 9 times, resulting in a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 7822.9
If we take 693 away from 720, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 8:
77 goes into 270 3 times with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 7822.93
If we subtract 231 from 270, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
The number 77 fits into 390 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7822.935
If we take 385 away from 390, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
When dividing 50 by 77, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 7822.935
Subtracting 0 from 50 leaves us 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.

Advancing to step 11:
When dividing 500 by 77, we get 6 with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 7822.93506
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
77 goes into 380 4 times with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 7822.935064
If we take 308 away from 380, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 13:
If we divide 720 by 77, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 7822.9350649
Subtracting 693 from 720 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 14:
The number 77 fits into 270 3 times, leaving a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 7822.93506493
Deduct 231 from 270 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 7822.93506493, and the remainder is 3.9e-08.
