521301 ÷ 57 
Our goal is to divide 521301 by 57.

Step 1:
The number 57 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
Subtracting 0 from 5 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 57

On to step 2:
52 divided by 57 is 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 57

Step 3:
521 divided by 57 is 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 513 from 521, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 57

Moving on to step 4:
When dividing 83 by 57, we get 1 with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtracting 57 from 83 leaves us with 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 57

On to step 5:
57 can be fit into 260 4 times, resulting in a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 914.0
If we take 228 away from 260, we end up with 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 57

Advancing to step 6:
If we divide 321 by 57, we get 5 and a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 9145.0
Deduct 285 from 321 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
If we divide 360 by 57, we get 6 and a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 9145.6
The remainder is 18 after subtracting 342 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
When dividing 180 by 57, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 9145.63
If we subtract 171 from 180, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
If we divide 90 by 57, we get 1 and a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 9145.631
If we take 57 away from 90, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 10:
The number 57 fits into 330 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 9145.6315
Deduct 285 from 330 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
If we divide 450 by 57, we get 7 and a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 9145.63157
If we take 399 away from 450, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 12:
510 divided by 57 is 8 with a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 9145.631578
If we take 456 away from 510, 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.

Advancing to step 13:
540 divided by 57 is 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 9145.6315789
If we subtract 513 from 540, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 14:
When dividing 270 by 57, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 9145.63157894
The remainder is 42 after subtracting 228 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 9145.63157894 with a balance of 4.2e-08.
