We look at the division of 810542 by 7 
Our goal is to divide 810542 by 7.

Step 1:
7 goes into 8 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 7

Moving on to step 2:
The number 7 fits into 11 1 times, leaving a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 7 from 11 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 7

Advancing to step 3:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 115.0
The remainder is 5 after subtracting 35 from 40.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 7

Let's proceed to step 4:
If we divide 55 by 7, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 1157.0
Subtracting 49 from 55 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 7

Going ahead to step 5:
7 can be fit into 64 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 11579.0
If we take 63 away from 64, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 7

On to step 6:
If we divide 12 by 7, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 115791.0
If we take 7 away from 12, we end up 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.

Let's proceed to step 7:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 115791.7
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.

Going ahead to step 8:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 115791.71
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 9:
If we divide 30 by 7, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 115791.714
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.

Going ahead to step 10:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 115791.7142
If we subtract 14 from 20, we 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.

Let's proceed to step 11:
60 divided by 7 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 115791.71428
Deduct 56 from 60 and we're left 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 12:
40 divided by 7 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 115791.714285
Deduct 35 from 40 and we're left 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 13:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 115791.7142857
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.

Advancing to step 14:
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: 115791.71428571
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.

The final outcome is 115791.71428571, with a leftover of 3e-09.
