We're dividing 54897277 by 7 
The aim is to understand the frequency of 7 in 54897277.

Let's proceed to step 1:
If we divide 5 by 7, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 7

On to step 2:
7 goes into 54 7 times with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 49 from 54 and we're left with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 7

Moving on to step 3:
7 can be fit into 58 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 78.0
Subtracting 56 from 58 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 7

Step 4:
The number 7 fits into 29 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 784.0
If we subtract 28 from 29, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 7

Step 5:
The number 7 fits into 17 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 7842.0
Subtract 14 from 17 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 7

Advancing to step 6:
7 goes into 32 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 78424.0
Subtracting 28 from 32 leaves us with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 7

Let's proceed to step 7:
47 divided by 7 is 6 with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 784246.0
Subtract 42 from 47 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 7

Moving on to step 8:
The number 7 fits into 57 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 7842468.0
Deduct 56 from 57 and we're left 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 9:
When dividing 10 by 7, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 7842468.1
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
When dividing 30 by 7, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 7842468.14
Subtracting 28 from 30 leaves us 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.

Let's proceed to step 11:
If we divide 20 by 7, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 7842468.142
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.

Advancing to step 12:
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: 7842468.1428
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.

Let's proceed to step 13:
When dividing 40 by 7, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7842468.14285
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 14:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7842468.142857
Subtract 49 from 50 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 15:
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: 7842468.1428571
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.

Moving on to step 16:
30 divided by 7 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 7842468.14285714
If we take 28 away from 30, we end up 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.

Our division results in 7842468.14285714 with a remaining 2e-09.
