We're dividing 54123443 by 537 
We want to divide 54123443 by 537.

Going ahead to step 1:
If we divide 5 by 537, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 537

On to step 2:
If we divide 54 by 537, we get 0 and a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Include the next digit (1) from the dividend after 54, then repeat: 541 / 537

Going ahead to step 3:
541 divided by 537 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 537 from 541 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 537

Moving on to step 4:
The number 537 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 537

Advancing to step 5:
If we divide 423 by 537, we get 0 and a remainder of 423.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 423 leaves us with 423.
Fetch the next digit (4) from the dividend, attach it to 423 and continue: 4234 / 537

Moving on to step 6:
4234 divided by 537 is 7 with a remainder of 475.
The next digit of our result is 7. 
Result so far: 1007.0
The remainder is 475 after subtracting 3759 from 4234.
Grab the next digit (4) from the dividend, add it to 475, then carry on: 4754 / 537

On to step 7:
The number 537 fits into 4754 8 times, leaving a remainder of 458.
The number 8 becomes the next digit in our result. 
Result so far: 10078.0
Deduct 4296 from 4754 and we're left with 458.
Append the next digit (3) from the dividend to 458 and continue with: 4583 / 537

Let's proceed to step 8:
537 can be fit into 4583 8 times, resulting in a remainder of 287.
Put 8 as the next digit of the answer. 
Result so far: 100788.0
If we subtract 4296 from 4583, we get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 9:
If we divide 2870 by 537, we get 5 and a remainder of 185.
The next digit of our result is 5. 
Result so far: 100788.5
Deduct 2685 from 2870 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 10:
537 can be fit into 1850 3 times, resulting in a remainder of 239.
Use 3 as the next digit of our solution. 
Result so far: 100788.53
Deduct 1611 from 1850 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 11:
2390 divided by 537 is 4 with a remainder of 242.
Record the quotient 4 as the next digit in the result. 
Result so far: 100788.534
If we subtract 2148 from 2390, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 12:
537 goes into 2420 4 times with a remainder of 272.
Put 4 as the next digit of the answer. 
Result so far: 100788.5344
Deduct 2148 from 2420 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The quotient of the division is 100788.5344, and the remainder is 0.00272.
