638700 divided by 63 
We're looking to find how many times 63 goes into 638700.

Let's proceed to step 1:
63 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 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.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 63 from 63 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 63

Advancing to step 3:
If we divide 8 by 63, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 63

Going ahead to step 4:
63 can be fit into 87 1 times, resulting in a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Deduct 63 from 87 and we're left with 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 63

Moving on to step 5:
240 divided by 63 is 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 1013.0
If we take 189 away from 240, we end up with 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 63

Step 6:
63 can be fit into 510 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 10138.0
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.

On to step 7:
63 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 10138.0
Subtracting 0 from 60 leaves us 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.

Advancing to step 8:
The number 63 fits into 600 9 times, leaving a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 10138.09
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.

Let's proceed to step 9:
The number 63 fits into 330 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 10138.095
Subtracting 315 from 330 leaves us 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.

Going ahead to step 10:
63 goes into 150 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 10138.0952
If we subtract 126 from 150, we get 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 11:
240 divided by 63 is 3 with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 10138.09523
Deduct 189 from 240 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 12:
510 divided by 63 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 10138.095238
Deduct 504 from 510 and we're left 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.

Advancing to step 13:
60 divided by 63 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 10138.095238
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 14:
600 divided by 63 is 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 10138.09523809
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.

The final outcome is 10138.09523809, with a leftover of 3.3e-08.
