30858930 divided by 521 
We want to divide 30858930 by 521.

On to step 1:
521 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 521

Let's proceed to step 2:
521 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 521

Step 3:
521 can be fit into 308 0 times, resulting in a remainder of 308.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 308 and we're left with 308.
Include the next digit (5) from the dividend after 308, then repeat: 3085 / 521

Let's proceed to step 4:
3085 divided by 521 is 5 with a remainder of 480.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 2605 from 3085, we get 480.
Bring next digit (8) of the dividend behind the 480 and repeat the process: 4808 / 521

Going ahead to step 5:
When dividing 4808 by 521, we get 9 with a remainder of 119.
The next digit of our result is 9. 
Result so far: 59.0
If we subtract 4689 from 4808, we get 119.
Append the next digit (9) from the dividend to 119 and continue with: 1199 / 521

Moving on to step 6:
1199 divided by 521 is 2 with a remainder of 157.
The next digit of our result is 2. 
Result so far: 592.0
Subtracting 1042 from 1199 leaves us with 157.
Bring next digit (3) of the dividend behind the 157 and repeat the process: 1573 / 521

Advancing to step 7:
1573 divided by 521 is 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 5923.0
If we subtract 1563 from 1573, we get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 521

Going ahead to step 8:
If we divide 100 by 521, we get 0 and a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 59230.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 9:
When dividing 1000 by 521, we get 1 with a remainder of 479.
Record the quotient 1 as the next digit in the result. 
Result so far: 59230.1
Deduct 521 from 1000 and we're left with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Let's proceed to step 10:
If we divide 4790 by 521, we get 9 and a remainder of 101.
Write down 9 as next digit of the result. 
Result so far: 59230.19
If we subtract 4689 from 4790, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 11:
521 goes into 1010 1 times with a remainder of 489.
The number 1 becomes the next digit in our result. 
Result so far: 59230.191
If we take 521 away from 1010, we end up with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Let's proceed to step 12:
521 goes into 4890 9 times with a remainder of 201.
Use 9 as the next digit of our solution. 
Result so far: 59230.1919
Subtracting 4689 from 4890 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 13:
521 can be fit into 2010 3 times, resulting in a remainder of 447.
Write down 3 as next digit of the result. 
Result so far: 59230.19193
The remainder is 447 after subtracting 1563 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Step 14:
If we divide 4470 by 521, we get 8 and a remainder of 302.
Put 8 as the next digit of the answer. 
Result so far: 59230.191938
The remainder is 302 after subtracting 4168 from 4470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 15:
3020 divided by 521 is 5 with a remainder of 415.
Record the quotient 5 as the next digit in the result. 
Result so far: 59230.1919385
Deduct 2605 from 3020 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 16:
4150 divided by 521 is 7 with a remainder of 503.
Use 7 as the next digit of our solution. 
Result so far: 59230.19193857
Subtract 3647 from 4150 to get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

The final outcome is 59230.19193857, with a leftover of 5.03e-07.
