Let's divide 800721 by 7
Our goal is to divide 800721 by 7.

Step 1:
If we divide 8 by 7, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 7 from 8 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 7

On to step 2:
10 divided by 7 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 7 from 10, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 7

Let's proceed to step 3:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Subtracting 28 from 30 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 7

Advancing to step 4:
If we divide 27 by 7, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 1143.0
Subtract 21 from 27 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 7

On to step 5:
If we divide 62 by 7, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 11438.0
Subtracting 56 from 62 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 7

Moving on to step 6:
When dividing 61 by 7, we get 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 114388.0
If we subtract 56 from 61, 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.

Advancing to step 7:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 114388.7
Subtract 49 from 50 to 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.

Going ahead to step 8:
10 divided by 7 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 114388.71
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.

Let's proceed to step 9:
When dividing 30 by 7, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 114388.714
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:
7 goes into 20 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 114388.7142
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.

Advancing to step 11:
When dividing 60 by 7, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 114388.71428
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 12:
40 divided by 7 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 114388.714285
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.

Step 13:
If we divide 50 by 7, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 114388.7142857
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.

Moving on to step 14:
When dividing 10 by 7, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 114388.71428571
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.

In conclusion, the division gives 114388.71428571 with a balance of 3e-09.
