We divide 19776054 by 7
The aim is to understand the frequency of 7 in 19776054.

Advancing to step 1:
7 goes into 1 0 times with 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 (9) from the dividend to 1 and continue with: 19 / 7

Advancing to step 2:
If we divide 19 by 7, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 14 from 19 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 7

Step 3:
7 goes into 57 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 56 from 57 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 7

On to step 4:
17 divided by 7 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 282.0
The remainder is 3 after subtracting 14 from 17.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 7

Moving on to step 5:
7 can be fit into 36 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 2825.0
Subtracting 35 from 36 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 7

Moving on to step 6:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 28251.0
The remainder is 3 after subtracting 7 from 10.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 7

Advancing to step 7:
35 divided by 7 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 282515.0
Subtract 35 from 35 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 7

Advancing to step 8:
7 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 2825150.0
If we take 0 away from 4, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 7, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 2825150.5
If we subtract 35 from 40, we get 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:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 2825150.57
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 2825150.571
If we take 7 away from 10, we end up with 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 12:
7 goes into 30 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 2825150.5714
Deduct 28 from 30 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.

Advancing to step 13:
If we divide 20 by 7, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2825150.57142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
If we divide 60 by 7, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 2825150.571428
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 15:
If we divide 40 by 7, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 2825150.5714285
Subtracting 35 from 40 leaves us 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.

Moving on to step 16:
50 divided by 7 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 2825150.57142857
If we take 49 away from 50, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 2825150.57142857 and a remainder of 1e-09.
