We divide 545455 by 7
Let's see how many times 7 fits into 545455.

Advancing to step 1:
7 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 7

On to step 2:
If we divide 54 by 7, we get 7 and a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 49 from 54 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 7

Going ahead to step 3:
The number 7 fits into 55 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 77.0
If we subtract 49 from 55, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 7

On to step 4:
7 can be fit into 64 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 779.0
If we subtract 63 from 64, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 7

Advancing to step 5:
15 divided by 7 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 7792.0
Subtract 14 from 15 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 7

Going ahead to step 6:
If we divide 15 by 7, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 77922.0
The remainder is 1 after subtracting 14 from 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 77922.1
Subtracting 7 from 10 leaves us 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.

Advancing to step 8:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 77922.14
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 9:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 77922.142
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
When dividing 60 by 7, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 77922.1428
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
If we divide 40 by 7, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 77922.14285
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.

Going ahead to step 12:
7 can be fit into 50 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 77922.142857
If we subtract 49 from 50, we 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.

Let's proceed to step 13:
7 goes into 10 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 77922.1428571
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.

On to step 14:
7 goes into 30 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 77922.14285714
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 77922.14285714, with a leftover of 2e-09.
