We look at the division of 775443 by 7 
We want to figure out the number of times 775443 can be divided by 7.

On to step 1:
7 goes into 7 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 7 from 7 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 7

Step 2:
If we divide 7 by 7, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 7 from 7 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 7

Advancing to step 3:
5 divided by 7 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 110.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 7

Moving on to step 4:
The number 7 fits into 54 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 1107.0
Subtracting 49 from 54 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 7

Step 5:
7 goes into 54 7 times with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 11077.0
Deduct 49 from 54 and we're left with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 7

Step 6:
The number 7 fits into 53 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 110777.0
Deduct 49 from 53 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.

Let's proceed to step 7:
When dividing 40 by 7, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 110777.5
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.

Advancing to step 8:
50 divided by 7 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 110777.57
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 9:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 110777.571
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.

Step 10:
30 divided by 7 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 110777.5714
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 11:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 110777.57142
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 12:
60 divided by 7 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 110777.571428
If we take 56 away from 60, we end up 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 13:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 110777.5714285
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.

Step 14:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 110777.57142857
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.

After the division, we end up with 110777.57142857 and a remainder of 1e-09.
