We look at the division of 503804 by 79 
We want to divide 503804 by 79.

Advancing to step 1:
5 divided by 79 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 79

Moving on to step 2:
50 divided by 79 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 79

On to step 3:
If we divide 503 by 79, we get 6 and a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 474 away from 503, we end up with 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 79

Advancing to step 4:
When dividing 298 by 79, we get 3 with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we subtract 237 from 298, we get 61.
Bring next digit (0) of the dividend behind the 61 and repeat the process: 610 / 79

Advancing to step 5:
When dividing 610 by 79, we get 7 with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 637.0
If we take 553 away from 610, we end up with 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 79

Advancing to step 6:
79 goes into 574 7 times with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 6377.0
Subtract 553 from 574 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
79 goes into 210 2 times with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 6377.2
Deduct 158 from 210 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
If we divide 520 by 79, we get 6 and a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 6377.26
Deduct 474 from 520 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
The number 79 fits into 460 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 6377.265
Deduct 395 from 460 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 10:
650 divided by 79 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 6377.2658
If we subtract 632 from 650, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
79 can be fit into 180 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 6377.26582
Deduct 158 from 180 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
The number 79 fits into 220 2 times, leaving a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 6377.265822
Subtract 158 from 220 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 6377.265822 with a remainder of 6.2e-06.
