Let's divide 421554 by 63
Let's see how many times 63 fits into 421554.

Going ahead to step 1:
63 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 63

Going ahead to step 2:
If we divide 42 by 63, we get 0 and a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 63

On to step 3:
The number 63 fits into 421 6 times, leaving a remainder of 43.
The next digit of our result is 6. 
Result so far: 6.0
If we take 378 away from 421, we end up with 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 63

Advancing to step 4:
If we divide 435 by 63, we get 6 and a remainder of 57.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we subtract 378 from 435, we get 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 63

Step 5:
When dividing 575 by 63, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 669.0
Deduct 567 from 575 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 63

Let's proceed to step 6:
The number 63 fits into 84 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 6691.0
The remainder is 21 after subtracting 63 from 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
If we divide 210 by 63, we get 3 and a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 6691.3
Subtract 189 from 210 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
The number 63 fits into 210 3 times, leaving a remainder of 21.
The next digit of our result is 3. 
Result so far: 6691.33
Deduct 189 from 210 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 6691.33 with a remainder of 0.021.
