We're dividing 102435 by 63 
Let's see how many times 63 fits into 102435.

Moving on to step 1:
When dividing 1 by 63, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 63

Step 2:
63 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 63

Advancing to step 3:
63 goes into 102 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 63 away from 102, we end up with 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 63

Let's proceed to step 4:
63 goes into 394 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 16 after subtracting 378 from 394.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 63

Let's proceed to step 5:
The number 63 fits into 163 2 times, leaving a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 162.0
The remainder is 37 after subtracting 126 from 163.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 63

Going ahead to step 6:
If we divide 375 by 63, we get 5 and a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 1625.0
Deduct 315 from 375 and we're left 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 7:
The number 63 fits into 600 9 times, leaving a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 1625.9
Subtract 567 from 600 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 8:
The number 63 fits into 330 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1625.95
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.

On to step 9:
150 divided by 63 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 1625.952
Subtracting 126 from 150 leaves us 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.

Let's proceed to step 10:
The number 63 fits into 240 3 times, leaving a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 1625.9523
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 11:
63 goes into 510 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 1625.95238
If we take 504 away from 510, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
The number 63 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 1625.95238
Deduct 0 from 60 and we're left 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 13:
When dividing 600 by 63, we get 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 1625.9523809
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.

Moving on to step 14:
If we divide 330 by 63, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1625.95238095
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.

After the division, we end up with 1625.95238095 and a remainder of 1.5e-08.
