We look at the division of 781394 by 7 
We want to divide 781394 by 7.

Advancing to step 1:
The number 7 fits into 7 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 7 away from 7, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 7

On to step 2:
7 goes into 8 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 7 from 8, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 7

Advancing to step 3:
When dividing 11 by 7, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
If we take 7 away from 11, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 7

Let's proceed to step 4:
When dividing 43 by 7, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 1116.0
Deduct 42 from 43 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 7

Advancing to step 5:
The number 7 fits into 19 2 times, leaving a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 11162.0
If we subtract 14 from 19, we get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 7

Going ahead to step 6:
The number 7 fits into 54 7 times, leaving a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 111627.0
The remainder is 5 after subtracting 49 from 54.
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:
When dividing 50 by 7, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 111627.7
If we subtract 49 from 50, we 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.

On to step 8:
When dividing 10 by 7, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 111627.71
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.

Going ahead to step 9:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 111627.714
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 10:
20 divided by 7 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 111627.7142
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.

Moving on to step 11:
7 goes into 60 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 111627.71428
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:
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: 111627.714285
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.

On to step 13:
50 divided by 7 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 111627.7142857
If we subtract 49 from 50, we 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.

Advancing to step 14:
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: 111627.71428571
If we subtract 7 from 10, we 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.

In conclusion, the division gives 111627.71428571 with a balance of 3e-09.
