We're dividing 126389 by 63 
Our goal is to divide 126389 by 63.

On to step 1:
63 goes into 1 0 times 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 (2) of the dividend behind the 1 and repeat the process: 12 / 63

On to step 2:
When dividing 12 by 63, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 63

Moving on to step 3:
126 divided by 63 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 126 from 126.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 63

On to step 4:
When dividing 3 by 63, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 63

Step 5:
63 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
If we subtract 0 from 38, we get 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 63

Let's proceed to step 6:
If we divide 389 by 63, we get 6 and a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 2006.0
Subtract 378 from 389 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.

Going ahead to step 7:
63 can be fit into 110 1 times, resulting in a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 2006.1
If we take 63 away from 110, we end up 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.

Moving on to step 8:
If we divide 470 by 63, we get 7 and a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 2006.17
If we subtract 441 from 470, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
63 can be fit into 290 4 times, resulting in a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 2006.174
Deduct 252 from 290 and we're left 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.

On to step 10:
If we divide 380 by 63, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 2006.1746
If we take 378 away from 380, we end up 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.

Step 11:
If we divide 20 by 63, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 2006.1746
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
63 goes into 200 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 2006.174603
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
The number 63 fits into 110 1 times, leaving a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 2006.1746031
If we take 63 away from 110, we end up 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.

Step 14:
If we divide 470 by 63, we get 7 and a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 2006.17460317
Deduct 441 from 470 and we're left 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.

The quotient of the division is 2006.17460317, and the remainder is 2.9e-08.
