We divide 30590978 by 521
We want to divide 30590978 by 521.

Advancing to step 1:
521 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 521

On to step 2:
30 divided by 521 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 521

Step 3:
521 goes into 305 0 times with a remainder of 305.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 305, we end up with 305.
Fetch the next digit (9) from the dividend, attach it to 305 and continue: 3059 / 521

On to step 4:
If we divide 3059 by 521, we get 5 and a remainder of 454.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 454 after subtracting 2605 from 3059.
Bring next digit (0) of the dividend behind the 454 and repeat the process: 4540 / 521

Let's proceed to step 5:
The number 521 fits into 4540 8 times, leaving a remainder of 372.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtracting 4168 from 4540 leaves us with 372.
Take the next digit (9) from the dividend and append it to 372, then repeat: 3729 / 521

Advancing to step 6:
3729 divided by 521 is 7 with a remainder of 82.
Write down 7 as next digit of the result. 
Result so far: 587.0
Subtract 3647 from 3729 to get 82.
Grab the next digit (7) from the dividend, add it to 82, then carry on: 827 / 521

Step 7:
If we divide 827 by 521, we get 1 and a remainder of 306.
Record the quotient 1 as the next digit in the result. 
Result so far: 5871.0
If we take 521 away from 827, we end up with 306.
Bring next digit (8) of the dividend behind the 306 and repeat the process: 3068 / 521

Going ahead to step 8:
521 can be fit into 3068 5 times, resulting in a remainder of 463.
The number 5 becomes the next digit in our result. 
Result so far: 58715.0
Subtracting 2605 from 3068 leaves us with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Going ahead to step 9:
If we divide 4630 by 521, we get 8 and a remainder of 462.
The next digit of our result is 8. 
Result so far: 58715.8
If we take 4168 away from 4630, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 10:
521 can be fit into 4620 8 times, resulting in a remainder of 452.
Record the quotient 8 as the next digit in the result. 
Result so far: 58715.88
If we subtract 4168 from 4620, we get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The final outcome is 58715.88, with a leftover of 0.452.
