Let's divide 801645 by 63
We're looking to find how many times 63 goes into 801645.

Advancing to step 1:
63 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 63

On to step 2:
63 goes into 80 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 63 from 80 to get 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 63

Moving on to step 3:
When dividing 171 by 63, we get 2 with a remainder of 45.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 126 from 171 and we're left with 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 63

Step 4:
The number 63 fits into 456 7 times, leaving a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Subtracting 441 from 456 leaves us with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 63

Step 5:
63 goes into 154 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 1272.0
Deduct 126 from 154 and we're left with 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 63

Step 6:
63 goes into 285 4 times with a remainder of 33.
The next digit of our result is 4. 
Result so far: 12724.0
Deduct 252 from 285 and we're left 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.

Advancing to step 7:
If we divide 330 by 63, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 12724.5
If we take 315 away from 330, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
63 can be fit into 150 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 12724.52
Subtract 126 from 150 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
If we divide 240 by 63, we get 3 and a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 12724.523
If we subtract 189 from 240, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 10:
If we divide 510 by 63, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 12724.5238
The remainder is 6 after subtracting 504 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
The number 63 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 12724.5238
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
The number 63 fits into 600 9 times, leaving a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 12724.523809
Subtracting 567 from 600 leaves us 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 13:
The number 63 fits into 330 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 12724.5238095
Subtract 315 from 330 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
150 divided by 63 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 12724.52380952
If we take 126 away from 150, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 12724.52380952, with a leftover of 2.4e-08.
