Let's divide 686227 by 77
The aim is to understand the frequency of 77 in 686227.

Step 1:
6 divided by 77 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 77

Advancing to step 2:
68 divided by 77 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 77

Going ahead to step 3:
When dividing 686 by 77, we get 8 with a remainder of 70.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 616 from 686, we get 70.
Include the next digit (2) from the dividend after 70, then repeat: 702 / 77

Let's proceed to step 4:
When dividing 702 by 77, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 89.0
If we take 693 away from 702, we end up with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 77

Advancing to step 5:
77 goes into 92 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 891.0
If we take 77 away from 92, we end up with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 77

Advancing to step 6:
When dividing 157 by 77, we get 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 8912.0
If we subtract 154 from 157, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
77 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 8912.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
77 goes into 300 3 times with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 8912.03
Deduct 231 from 300 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
When dividing 690 by 77, we get 8 with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 8912.038
Subtracting 616 from 690 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 10:
77 can be fit into 740 9 times, resulting in a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 8912.0389
If we subtract 693 from 740, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 11:
470 divided by 77 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 8912.03896
Subtract 462 from 470 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
If we divide 80 by 77, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 8912.038961
Subtract 77 from 80 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
The number 77 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 8912.038961
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
The number 77 fits into 300 3 times, leaving a remainder of 69.
The next digit of our result is 3. 
Result so far: 8912.03896103
Subtract 231 from 300 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The final result is 8912.03896103 with a remainder of 6.9e-08.
