We look at the division of 16016831 by 777 
The aim is to understand the frequency of 777 in 16016831.

Moving on to step 1:
The number 777 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 777

Going ahead to step 2:
777 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 777

Advancing to step 3:
If we divide 160 by 777, we get 0 and a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 160 leaves us with 160.
Append the next digit (1) from the dividend to 160 and continue with: 1601 / 777

Going ahead to step 4:
If we divide 1601 by 777, we get 2 and a remainder of 47.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1554 from 1601 and we're left with 47.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 777

Going ahead to step 5:
If we divide 476 by 777, we get 0 and a remainder of 476.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 476 and we're left with 476.
Take the next digit (8) from the dividend and append it to 476, then repeat: 4768 / 777

Moving on to step 6:
4768 divided by 777 is 6 with a remainder of 106.
Put 6 as the next digit of the answer. 
Result so far: 206.0
Subtracting 4662 from 4768 leaves us with 106.
Grab the next digit (3) from the dividend, add it to 106, then carry on: 1063 / 777

On to step 7:
The number 777 fits into 1063 1 times, leaving a remainder of 286.
The number 1 becomes the next digit in our result. 
Result so far: 2061.0
If we take 777 away from 1063, we end up with 286.
Fetch the next digit (1) from the dividend, attach it to 286 and continue: 2861 / 777

Step 8:
If we divide 2861 by 777, we get 3 and a remainder of 530.
Write down 3 as next digit of the result. 
Result so far: 20613.0
Subtract 2331 from 2861 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 9:
777 goes into 5300 6 times with a remainder of 638.
The number 6 becomes the next digit in our result. 
Result so far: 20613.6
If we take 4662 away from 5300, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Moving on to step 10:
If we divide 6380 by 777, we get 8 and a remainder of 164.
The next digit of our result is 8. 
Result so far: 20613.68
Deduct 6216 from 6380 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 11:
When dividing 1640 by 777, we get 2 with a remainder of 86.
Write down 2 as next digit of the result. 
Result so far: 20613.682
If we take 1554 away from 1640, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 12:
860 divided by 777 is 1 with a remainder of 83.
Put 1 as the next digit of the answer. 
Result so far: 20613.6821
Deduct 777 from 860 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 13:
830 divided by 777 is 1 with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 20613.68211
Subtracting 777 from 830 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final result is 20613.68211 with a remainder of 5.3e-05.
