We look at the division of 639668 by 63 
Our goal is to divide 639668 by 63.

Moving on to step 1:
63 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 63

Going ahead to step 2:
63 goes into 63 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 63 from 63 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 63

Let's proceed to step 3:
9 divided by 63 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 63

Let's proceed to step 4:
63 goes into 96 1 times with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtract 63 from 96 to get 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 63

Let's proceed to step 5:
63 goes into 336 5 times with a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 1015.0
If we subtract 315 from 336, we get 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 63

Going ahead to step 6:
When dividing 218 by 63, we get 3 with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 10153.0
If we take 189 away from 218, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
The number 63 fits into 290 4 times, leaving a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 10153.4
The remainder is 38 after subtracting 252 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
If we divide 380 by 63, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 10153.46
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
When dividing 20 by 63, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10153.46
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
63 can be fit into 200 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 10153.4603
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 11:
When dividing 110 by 63, we get 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 10153.46031
Deduct 63 from 110 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 12:
The number 63 fits into 470 7 times, leaving a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 10153.460317
Subtracting 441 from 470 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
The number 63 fits into 290 4 times, leaving a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 10153.4603174
If we take 252 away from 290, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
The number 63 fits into 380 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 10153.46031746
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 10153.46031746 with a balance of 2e-09.
