Let's divide 67982790 by 521
We want to divide 67982790 by 521.

Going ahead to step 1:
When dividing 6 by 521, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 521

Step 2:
67 divided by 521 is 0 with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Include the next digit (9) from the dividend after 67, then repeat: 679 / 521

Let's proceed to step 3:
521 goes into 679 1 times with a remainder of 158.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 521 from 679 leaves us with 158.
Bring next digit (8) of the dividend behind the 158 and repeat the process: 1588 / 521

On to step 4:
521 goes into 1588 3 times with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 1563 from 1588 to get 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 521

Step 5:
521 goes into 252 0 times with a remainder of 252.
Put 0 as the next digit of the answer. 
Result so far: 130.0
Subtract 0 from 252 to get 252.
Bring next digit (7) of the dividend behind the 252 and repeat the process: 2527 / 521

Advancing to step 6:
When dividing 2527 by 521, we get 4 with a remainder of 443.
Use 4 as the next digit of our solution. 
Result so far: 1304.0
Subtracting 2084 from 2527 leaves us with 443.
Include the next digit (9) from the dividend after 443, then repeat: 4439 / 521

Step 7:
If we divide 4439 by 521, we get 8 and a remainder of 271.
The next digit of our result is 8. 
Result so far: 13048.0
If we take 4168 away from 4439, we end up with 271.
Grab the next digit (0) from the dividend, add it to 271, then carry on: 2710 / 521

Let's proceed to step 8:
521 can be fit into 2710 5 times, resulting in a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 130485.0
Deduct 2605 from 2710 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 9:
The number 521 fits into 1050 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 130485.2
The remainder is 8 after subtracting 1042 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 521 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 130485.2
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
521 goes into 800 1 times with a remainder of 279.
Write down 1 as next digit of the result. 
Result so far: 130485.201
If we take 521 away from 800, we end up with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

On to step 12:
When dividing 2790 by 521, we get 5 with a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 130485.2015
Subtracting 2605 from 2790 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 13:
The number 521 fits into 1850 3 times, leaving a remainder of 287.
The next digit of our result is 3. 
Result so far: 130485.20153
Subtract 1563 from 1850 to get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Moving on to step 14:
The number 521 fits into 2870 5 times, leaving a remainder of 265.
The next digit of our result is 5. 
Result so far: 130485.201535
Subtract 2605 from 2870 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 15:
When dividing 2650 by 521, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 130485.2015355
The remainder is 45 after subtracting 2605 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 130485.2015355 with a remainder of 4.5e-07.
