We want to divide 81010751 by 7.

Let's proceed to step 1:
8 divided by 7 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 7 from 8 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 7

Going ahead to step 2:
11 divided by 7 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 7 from 11 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 7

Moving on to step 3:
When dividing 40 by 7, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 115.0
If we subtract 35 from 40, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 7

Moving on to step 4:
7 goes into 51 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 1157.0
If we subtract 49 from 51, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 7

Step 5:
When dividing 20 by 7, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 11572.0
If we subtract 14 from 20, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 7

Going ahead to step 6:
When dividing 67 by 7, we get 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 115729.0
The remainder is 4 after subtracting 63 from 67.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 7

Advancing to step 7:
If we divide 45 by 7, we get 6 and a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 1157296.0
If we take 42 away from 45, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 7

Let's proceed to step 8:
31 divided by 7 is 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 11572964.0
Subtract 28 from 31 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.

Going ahead to step 9:
7 goes into 30 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 11572964.4
Subtract 28 from 30 to 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.

Going ahead to step 10:
If we divide 20 by 7, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 11572964.42
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 11:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 11572964.428
Subtracting 56 from 60 leaves us 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.

Moving on to step 12:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 11572964.4285
Subtract 35 from 40 to 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.

Let's proceed to step 13:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 11572964.42857
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.

On to step 14:
When dividing 10 by 7, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 11572964.428571
Deduct 7 from 10 and we're left 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 15:
7 goes into 30 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 11572964.4285714
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.

On to step 16:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 11572964.42857142
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.

Our division results in 11572964.42857142 with a remaining 6e-09.
