We look at the division of 9023817 by 521 
Let's see how many times 521 fits into 9023817.

Step 1:
If we divide 9 by 521, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 521

Moving on to step 2:
521 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Take the next digit (2) from the dividend and append it to 90, then repeat: 902 / 521

On to step 3:
521 can be fit into 902 1 times, resulting in a remainder of 381.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 521 from 902 leaves us with 381.
Bring next digit (3) of the dividend behind the 381 and repeat the process: 3813 / 521

On to step 4:
The number 521 fits into 3813 7 times, leaving a remainder of 166.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 3647 from 3813 leaves us with 166.
Grab the next digit (8) from the dividend, add it to 166, then carry on: 1668 / 521

Advancing to step 5:
521 goes into 1668 3 times with a remainder of 105.
Record the quotient 3 as the next digit in the result. 
Result so far: 173.0
Deduct 1563 from 1668 and we're left with 105.
Grab the next digit (1) from the dividend, add it to 105, then carry on: 1051 / 521

Step 6:
The number 521 fits into 1051 2 times, leaving a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 1732.0
The remainder is 9 after subtracting 1042 from 1051.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 521

Step 7:
The number 521 fits into 97 0 times, leaving a remainder of 97.
The next digit of our result is 0. 
Result so far: 17320.0
If we take 0 away from 97, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 8:
521 can be fit into 970 1 times, resulting in a remainder of 449.
Use 1 as the next digit of our solution. 
Result so far: 17320.1
If we take 521 away from 970, we end up with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Let's proceed to step 9:
When dividing 4490 by 521, we get 8 with a remainder of 322.
Put 8 as the next digit of the answer. 
Result so far: 17320.18
Subtracting 4168 from 4490 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 10:
The number 521 fits into 3220 6 times, leaving a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 17320.186
If we subtract 3126 from 3220, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 11:
521 can be fit into 940 1 times, resulting in a remainder of 419.
Write down 1 as next digit of the result. 
Result so far: 17320.1861
If we take 521 away from 940, we end up with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Going ahead to step 12:
521 can be fit into 4190 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 17320.18618
Subtracting 4168 from 4190 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
The number 521 fits into 220 0 times, leaving a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 17320.18618
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 14:
When dividing 2200 by 521, we get 4 with a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 17320.1861804
If we take 2084 away from 2200, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 15:
521 can be fit into 1160 2 times, resulting in a remainder of 118.
The next digit of our result is 2. 
Result so far: 17320.18618042
Subtracting 1042 from 1160 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

In conclusion, the division gives 17320.18618042 with a balance of 1.18e-07.
