Let's divide 126903 by 53
We want to figure out the number of times 126903 can be divided by 53.

On to step 1:
53 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 53

Step 2:
If we divide 12 by 53, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 53

On to step 3:
The number 53 fits into 126 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 106 away from 126, we end up with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 53

Going ahead to step 4:
209 divided by 53 is 3 with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 159 from 209 leaves us with 50.
Take the next digit (0) from the dividend and append it to 50, then repeat: 500 / 53

Advancing to step 5:
500 divided by 53 is 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 239.0
Subtract 477 from 500 to get 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 53

Let's proceed to step 6:
The number 53 fits into 233 4 times, leaving a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 2394.0
The remainder is 21 after subtracting 212 from 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
210 divided by 53 is 3 with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 2394.3
Subtract 159 from 210 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 8:
The number 53 fits into 510 9 times, leaving a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 2394.39
Subtracting 477 from 510 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
53 can be fit into 330 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 2394.396
The remainder is 12 after subtracting 318 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
53 goes into 120 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2394.3962
Subtract 106 from 120 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
The number 53 fits into 140 2 times, leaving a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 2394.39622
Subtract 106 from 140 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 2394.39622 with a balance of 3.4e-05.
