503390 divided by 79 
We want to figure out the number of times 503390 can be divided by 79.

Step 1:
79 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 79

Advancing to step 2:
The number 79 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 79

Going ahead to step 3:
If we divide 503 by 79, we get 6 and a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 474 from 503 to get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 79

Step 4:
The number 79 fits into 293 3 times, leaving a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtracting 237 from 293 leaves us with 56.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 79

On to step 5:
If we divide 569 by 79, we get 7 and a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 637.0
The remainder is 16 after subtracting 553 from 569.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 79

Step 6:
79 can be fit into 160 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 6372.0
If we take 158 away from 160, we end up 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.

Moving on to step 7:
The number 79 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6372.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
If we divide 200 by 79, we get 2 and a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 6372.02
Subtract 158 from 200 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
The number 79 fits into 420 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 6372.025
The remainder is 25 after subtracting 395 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
79 can be fit into 250 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 6372.0253
If we take 237 away from 250, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
The number 79 fits into 130 1 times, leaving a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 6372.02531
Deduct 79 from 130 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 12:
510 divided by 79 is 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 6372.025316
Subtracting 474 from 510 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
79 goes into 360 4 times with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 6372.0253164
Subtract 316 from 360 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
79 goes into 440 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 6372.02531645
If we take 395 away from 440, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 6372.02531645 and a remainder of 4.5e-08.
