Let's divide 353799 by 7
We're looking to find how many times 7 goes into 353799.

Advancing to step 1:
3 divided by 7 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 7

Advancing to step 2:
7 can be fit into 35 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 35 away from 35, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 7

Let's proceed to step 3:
7 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 7

Going ahead to step 4:
When dividing 37 by 7, we get 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 505.0
If we subtract 35 from 37, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 7

Advancing to step 5:
The number 7 fits into 29 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 5054.0
Subtract 28 from 29 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 7

Moving on to step 6:
If we divide 19 by 7, we get 2 and a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 50542.0
Deduct 14 from 19 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.

Step 7:
If we divide 50 by 7, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 50542.7
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.

On 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: 50542.71
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.

Advancing to step 9:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 50542.714
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.

Let's proceed to step 10:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 50542.7142
If we take 14 away from 20, we end up 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:
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: 50542.71428
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.

Step 12:
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: 50542.714285
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.

Moving on 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: 50542.7142857
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.

Step 14:
10 divided by 7 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 50542.71428571
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.

The final result is 50542.71428571 with a remainder of 3e-09.
