729812 ÷ 7 
We want to figure out the number of times 729812 can be divided by 7.

Step 1:
The number 7 fits into 7 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 7 from 7 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 7

On to step 2:
7 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 7

On to step 3:
7 can be fit into 29 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtract 28 from 29 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 7

Moving on to step 4:
7 goes into 18 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1042.0
The remainder is 4 after subtracting 14 from 18.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 7

Step 5:
41 divided by 7 is 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 10425.0
Deduct 35 from 41 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 7

Going ahead to step 6:
7 can be fit into 62 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 104258.0
Subtracting 56 from 62 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.

Going ahead to step 7:
If we divide 60 by 7, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 104258.8
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.

Advancing to step 8:
7 goes into 40 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 104258.85
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
When dividing 50 by 7, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 104258.857
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.

Step 10:
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: 104258.8571
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.

Advancing to step 11:
When dividing 30 by 7, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 104258.85714
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.

On to step 12:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 104258.857142
Deduct 14 from 20 and we're left 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 13:
When dividing 60 by 7, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 104258.8571428
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
7 goes into 40 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 104258.85714285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 104258.85714285 with a remainder of 5e-09.
