521138 divided by 79 
We want to figure out the number of times 521138 can be divided by 79.

Going ahead to step 1:
The number 79 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 79

On to step 2:
79 goes into 52 0 times with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 79

Step 3:
79 can be fit into 521 6 times, resulting in a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 474 from 521 and we're left with 47.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 79

Moving on to step 4:
If we divide 471 by 79, we get 5 and a remainder of 76.
The next digit of our result is 5. 
Result so far: 65.0
If we subtract 395 from 471, we get 76.
Fetch the next digit (3) from the dividend, attach it to 76 and continue: 763 / 79

Going ahead to step 5:
If we divide 763 by 79, we get 9 and a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 659.0
Subtracting 711 from 763 leaves us with 52.
Grab the next digit (8) from the dividend, add it to 52, then carry on: 528 / 79

Step 6:
79 goes into 528 6 times with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 6596.0
If we take 474 away from 528, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
540 divided by 79 is 6 with a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 6596.6
The remainder is 66 after subtracting 474 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
660 divided by 79 is 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 6596.68
Subtract 632 from 660 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
When dividing 280 by 79, we get 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 6596.683
Subtracting 237 from 280 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 10:
430 divided by 79 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 6596.6835
If we subtract 395 from 430, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 11:
350 divided by 79 is 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 6596.68354
The remainder is 34 after subtracting 316 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
If we divide 340 by 79, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 6596.683544
Subtract 316 from 340 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 6596.683544 with a balance of 2.4e-06.
