81460497 ÷ 7 
Our goal is to divide 81460497 by 7.

Let's proceed to step 1:
If we divide 8 by 7, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 7 from 8 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 7

Step 2:
The number 7 fits into 11 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 4 after subtracting 7 from 11.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 7

Moving on to step 3:
7 can be fit into 44 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Subtract 42 from 44 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 7

Going ahead to step 4:
7 can be fit into 26 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 1163.0
If we take 21 away from 26, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 7

Going ahead to step 5:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 11637.0
The remainder is 1 after subtracting 49 from 50.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 7

On to step 6:
If we divide 14 by 7, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 116372.0
If we take 14 away from 14, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 7

Let's proceed to step 7:
If we divide 9 by 7, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 1163721.0
Subtract 7 from 9 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 7

On to step 8:
7 can be fit into 27 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 11637213.0
If we subtract 21 from 27, 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.

Advancing to step 9:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 11637213.8
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.

Advancing to step 10:
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: 11637213.85
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
When dividing 50 by 7, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 11637213.857
The remainder is 1 after subtracting 49 from 50.
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 12:
10 divided by 7 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 11637213.8571
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 13:
When dividing 30 by 7, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 11637213.85714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 11637213.857142
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.

Going ahead to step 15:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 11637213.8571428
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 16:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 11637213.85714285
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.

The final result is 11637213.85714285 with a remainder of 5e-09.
