Let's divide 138403 by 63
Our goal is to divide 138403 by 63.

Moving on to step 1:
1 divided by 63 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 63

On to step 2:
The number 63 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 63

On to step 3:
When dividing 138 by 63, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 12 after subtracting 126 from 138.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 63

Advancing to step 4:
The number 63 fits into 124 1 times, leaving a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 63 from 124 and we're left with 61.
Grab the next digit (0) from the dividend, add it to 61, then carry on: 610 / 63

Step 5:
The number 63 fits into 610 9 times, leaving a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 219.0
The remainder is 43 after subtracting 567 from 610.
Fetch the next digit (3) from the dividend, attach it to 43 and continue: 433 / 63

Let's proceed to step 6:
63 goes into 433 6 times with a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 2196.0
If we subtract 378 from 433, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 7:
550 divided by 63 is 8 with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 2196.8
Deduct 504 from 550 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
When dividing 460 by 63, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 2196.87
The remainder is 19 after subtracting 441 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
63 can be fit into 190 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 2196.873
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
The number 63 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2196.873
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
When dividing 100 by 63, we get 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 2196.87301
Subtract 63 from 100 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 12:
63 can be fit into 370 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 2196.873015
If we subtract 315 from 370, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 13:
63 goes into 550 8 times with a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 2196.8730158
If we take 504 away from 550, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
If we divide 460 by 63, we get 7 and a remainder of 19.
The next digit of our result is 7. 
Result so far: 2196.87301587
Deduct 441 from 460 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 2196.87301587, and the remainder is 1.9e-08.
