521348 ÷ 63 
Our goal is to divide 521348 by 63.

Moving on to step 1:
63 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our 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 / 63

On to step 2:
When dividing 52 by 63, we get 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 63

Advancing to step 3:
521 divided by 63 is 8 with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 504 from 521 and we're left with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 63

Going ahead to step 4:
When dividing 173 by 63, we get 2 with a remainder of 47.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtract 126 from 173 to get 47.
Bring next digit (4) of the dividend behind the 47 and repeat the process: 474 / 63

Going ahead to step 5:
If we divide 474 by 63, we get 7 and a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 827.0
If we subtract 441 from 474, we get 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 63

Let's proceed to step 6:
338 divided by 63 is 5 with a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 8275.0
If we subtract 315 from 338, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
230 divided by 63 is 3 with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 8275.3
Subtract 189 from 230 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 8:
If we divide 410 by 63, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 8275.36
Subtract 378 from 410 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
320 divided by 63 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 8275.365
Subtract 315 from 320 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
63 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 8275.365
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
63 can be fit into 500 7 times, resulting in a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 8275.36507
The remainder is 59 after subtracting 441 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 12:
When dividing 590 by 63, we get 9 with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 8275.365079
If we subtract 567 from 590, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
63 goes into 230 3 times with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 8275.3650793
Subtracting 189 from 230 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 14:
63 can be fit into 410 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 8275.36507936
Subtract 378 from 410 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 8275.36507936 with a remainder of 3.2e-08.
