423972 ÷ 63 
We want to divide 423972 by 63.

Let's proceed to step 1:
The number 63 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 63

On to step 2:
When dividing 42 by 63, we get 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 63

Moving on to step 3:
63 goes into 423 6 times with a remainder of 45.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 378 from 423, we get 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 63

Step 4:
63 goes into 459 7 times with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 67.0
If we take 441 away from 459, we end up with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 63

Advancing to step 5:
If we divide 187 by 63, we get 2 and a remainder of 61.
Write down 2 as next digit of the result. 
Result so far: 672.0
If we subtract 126 from 187, we get 61.
Grab the next digit (2) from the dividend, add it to 61, then carry on: 612 / 63

Moving on to step 6:
63 goes into 612 9 times with a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 6729.0
Subtracting 567 from 612 leaves us 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.

Let's proceed to step 7:
63 can be fit into 450 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 6729.7
If we subtract 441 from 450, we 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.

Advancing to step 8:
When dividing 90 by 63, we get 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 6729.71
The remainder is 27 after subtracting 63 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
270 divided by 63 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 6729.714
If we subtract 252 from 270, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
If we divide 180 by 63, we get 2 and a remainder of 54.
The next digit of our result is 2. 
Result so far: 6729.7142
Subtract 126 from 180 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
63 can be fit into 540 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 6729.71428
If we take 504 away from 540, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
When dividing 360 by 63, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 6729.714285
If we subtract 315 from 360, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 13:
If we divide 450 by 63, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 6729.7142857
Deduct 441 from 450 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
When dividing 90 by 63, we get 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 6729.71428571
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.

After the division, we end up with 6729.71428571 and a remainder of 2.7e-08.
