Let's divide 606201 by 77
The aim is to understand the frequency of 77 in 606201.

Going ahead to step 1:
When dividing 6 by 77, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 77

Step 2:
If we divide 60 by 77, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 60 after subtracting 0 from 60.
Take the next digit (6) from the dividend and append it to 60, then repeat: 606 / 77

Step 3:
When dividing 606 by 77, we get 7 with a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 539 away from 606, we end up with 67.
Bring next digit (2) of the dividend behind the 67 and repeat the process: 672 / 77

Advancing to step 4:
77 goes into 672 8 times with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Deduct 616 from 672 and we're left with 56.
Append the next digit (0) from the dividend to 56 and continue with: 560 / 77

Moving on to step 5:
If we divide 560 by 77, we get 7 and a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 787.0
Subtract 539 from 560 to get 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 77

On to step 6:
If we divide 211 by 77, we get 2 and a remainder of 57.
Record the quotient 2 as the next digit in the result. 
Result so far: 7872.0
If we subtract 154 from 211, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 7:
77 goes into 570 7 times with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 7872.7
Subtracting 539 from 570 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 8:
The number 77 fits into 310 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 7872.74
Deduct 308 from 310 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 77, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7872.74
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
200 divided by 77 is 2 with a remainder of 46.
The next digit of our result is 2. 
Result so far: 7872.7402
If we subtract 154 from 200, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
77 goes into 460 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 7872.74025
Deduct 385 from 460 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 12:
The number 77 fits into 750 9 times, leaving a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 7872.740259
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 13:
77 can be fit into 570 7 times, resulting in a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 7872.7402597
Subtracting 539 from 570 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 14:
310 divided by 77 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 7872.74025974
The remainder is 2 after subtracting 308 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 7872.74025974 with a remaining 2e-09.
