We look at the division of 811403 by 79 
Let's see how many times 79 fits into 811403.

Step 1:
79 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 79

On to step 2:
The number 79 fits into 81 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 2 after subtracting 79 from 81.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 79

On to step 3:
79 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 79

Going ahead to step 4:
79 can be fit into 214 2 times, resulting in a remainder of 56.
The next digit of our result is 2. 
Result so far: 102.0
Deduct 158 from 214 and we're left with 56.
Append the next digit (0) from the dividend to 56 and continue with: 560 / 79

Moving on to step 5:
When dividing 560 by 79, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 1027.0
If we subtract 553 from 560, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 79

Step 6:
73 divided by 79 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 10270.0
Subtract 0 from 73 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 7:
79 can be fit into 730 9 times, resulting in a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 10270.9
Subtracting 711 from 730 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
79 can be fit into 190 2 times, resulting in a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 10270.92
If we subtract 158 from 190, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
If we divide 320 by 79, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 10270.924
If we take 316 away from 320, 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 10:
79 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10270.924
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
79 goes into 400 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 10270.92405
Deduct 395 from 400 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 12:
79 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 10270.92405
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
The number 79 fits into 500 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 10270.9240506
Subtracting 474 from 500 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
79 can be fit into 260 3 times, resulting in a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 10270.92405063
If we take 237 away from 260, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 10270.92405063 with a remainder of 2.3e-08.
