We look at the division of 77857 by 63 
We're looking to find how many times 63 goes into 77857.

On to step 1:
7 divided by 63 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 63

Step 2:
63 goes into 77 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 63 from 77 leaves us with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 63

Moving on to step 3:
148 divided by 63 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 126 away from 148, we end up with 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 63

Advancing to step 4:
63 can be fit into 225 3 times, resulting in a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 123.0
Deduct 189 from 225 and we're left with 36.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 63

Step 5:
63 goes into 367 5 times with a remainder of 52.
Put 5 as the next digit of the answer. 
Result so far: 1235.0
Subtract 315 from 367 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 6:
If we divide 520 by 63, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 1235.8
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
The number 63 fits into 160 2 times, leaving a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 1235.82
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
63 can be fit into 340 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 1235.825
Deduct 315 from 340 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
250 divided by 63 is 3 with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 1235.8253
Subtracting 189 from 250 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 10:
63 goes into 610 9 times with a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 1235.82539
If we subtract 567 from 610, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 11:
If we divide 430 by 63, we get 6 and a remainder of 52.
The next digit of our result is 6. 
Result so far: 1235.825396
Subtract 378 from 430 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
The number 63 fits into 520 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 1235.8253968
Subtracting 504 from 520 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
160 divided by 63 is 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 1235.82539682
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 1235.82539682 with a remaining 3.4e-08.
