We look at the division of 731408 by 7 
Let's see how many times 7 fits into 731408.

On to step 1:
If we divide 7 by 7, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 7 from 7, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 7

Moving on to step 2:
3 divided by 7 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 7

Step 3:
7 goes into 31 4 times with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Deduct 28 from 31 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 7

Advancing to step 4:
If we divide 34 by 7, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 1044.0
Subtracting 28 from 34 leaves us with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 7

Moving on to step 5:
7 goes into 60 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10448.0
Subtract 56 from 60 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 7

Going ahead to step 6:
When dividing 48 by 7, we get 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 104486.0
Subtracting 42 from 48 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.

On to step 7:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 104486.8
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.

Going ahead to step 8:
When dividing 40 by 7, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 104486.85
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.

Advancing to step 9:
50 divided by 7 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 104486.857
Deduct 49 from 50 and we're left 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.

Going ahead to step 10:
If we divide 10 by 7, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 104486.8571
Subtracting 7 from 10 leaves us 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 11:
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: 104486.85714
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.

On to step 12:
7 goes into 20 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 104486.857142
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.

Moving on to step 13:
7 goes into 60 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 104486.8571428
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.

Going ahead to step 14:
If we divide 40 by 7, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 104486.85714285
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.

After the division, we end up with 104486.85714285 and a remainder of 5e-09.
