Let's divide 354403 by 7
We want to divide 354403 by 7.

On to step 1:
The number 7 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 7

Going ahead to step 2:
7 goes into 35 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 0 after subtracting 35 from 35.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 7

On to step 3:
The number 7 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 7

Moving on to step 4:
7 can be fit into 44 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 506.0
Deduct 42 from 44 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 7

Moving on to step 5:
If we divide 20 by 7, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 5062.0
Deduct 14 from 20 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 7

Advancing to step 6:
The number 7 fits into 63 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 50629.0
If we take 63 away from 63, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
0 divided by 7 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 50629.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 7, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 50629.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 50629.0, with a leftover of 0.0.
