Put 6 as the next digit of the answer. 
Result so far: 1436.0
If we take 378 away from 422, we end up with 44.
Fetch the next digit (0) from the dividend, attach it to 44 and continue: 440 / 63

Going ahead to step 6:
63 can be fit into 440 6 times, resulting in a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 14366.0
Subtract 378 from 440 to get 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 63

Advancing to step 7:
63 goes into 620 9 times with a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 143669.0
Subtracting 567 from 620 leaves us with 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 63

Let's proceed to step 8:
If we divide 531 by 63, we get 8 and a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 1436698.0
If we take 504 away from 531, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
If we divide 270 by 63, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 1436698.4
The remainder is 18 after subtracting 252 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
180 divided by 63 is 2 with a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 1436698.42
Subtracting 126 from 180 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 11:
When dividing 540 by 63, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 1436698.428
The remainder is 36 after subtracting 504 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
If we divide 360 by 63, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1436698.4285
Deduct 315 from 360 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 13:
63 can be fit into 450 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 1436698.42857
Subtract 441 from 450 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
When dividing 90 by 63, we get 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1436698.428571
Subtracting 63 from 90 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 15:
If we divide 270 by 63, we get 4 and a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 1436698.4285714
If we take 252 away from 270, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 16:
63 goes into 180 2 times with a remainder of 54.
The next digit of our result is 2. 
Result so far: 1436698.42857142
Deduct 126 from 180 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.
