Let's divide 54780385 by 7
Our goal is to divide 54780385 by 7.

Going ahead to step 1:
5 divided by 7 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 7

On to step 2:
54 divided by 7 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 5 after subtracting 49 from 54.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 7

Moving on to step 3:
7 goes into 57 8 times with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Deduct 56 from 57 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 7

Going ahead to step 4:
18 divided by 7 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 782.0
Subtract 14 from 18 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 7

Going ahead to step 5:
7 goes into 40 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 7825.0
The remainder is 5 after subtracting 35 from 40.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 7

Let's proceed to step 6:
7 can be fit into 53 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 78257.0
Subtracting 49 from 53 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 7

Step 7:
7 can be fit into 48 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 782576.0
Deduct 42 from 48 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 7

Let's proceed to step 8:
7 goes into 65 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 7825769.0
The remainder is 2 after subtracting 63 from 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
7 goes into 20 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 7825769.2
Subtract 14 from 20 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
When dividing 60 by 7, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 7825769.28
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.

Let's proceed to step 11:
If we divide 40 by 7, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 7825769.285
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.

On to step 12:
When dividing 50 by 7, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 7825769.2857
Deduct 49 from 50 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.

Moving on to step 13:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 7825769.28571
Subtract 7 from 10 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 14:
7 goes into 30 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 7825769.285714
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.

On to step 15:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 7825769.2857142
Deduct 14 from 20 and we're left 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.

Advancing to step 16:
When dividing 60 by 7, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 7825769.28571428
Subtract 56 from 60 to 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.

In conclusion, the division gives 7825769.28571428 with a balance of 4e-09.
