Let's divide 126423 by 71
We're looking to find how many times 71 goes into 126423.

Advancing to step 1:
71 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 71

Advancing to step 2:
71 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 71

Let's proceed to step 3:
If we divide 126 by 71, we get 1 and a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 71 from 126 and we're left with 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 71

Going ahead to step 4:
554 divided by 71 is 7 with a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 497 from 554, we get 57.
Bring next digit (2) of the dividend behind the 57 and repeat the process: 572 / 71

Moving on to step 5:
If we divide 572 by 71, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
Subtracting 568 from 572 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 71

Let's proceed to step 6:
When dividing 43 by 71, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 1780.0
Subtract 0 from 43 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
71 can be fit into 430 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1780.6
Subtracting 426 from 430 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
71 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1780.6
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
71 goes into 400 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1780.605
If we subtract 355 from 400, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
If we divide 450 by 71, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 1780.6056
Subtract 426 from 450 to 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.

Going ahead to step 11:
71 can be fit into 240 3 times, resulting in a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 1780.60563
The remainder is 27 after subtracting 213 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
When dividing 270 by 71, we get 3 with a remainder of 57.
The next digit of our result is 3. 
Result so far: 1780.605633
Subtracting 213 from 270 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final outcome is 1780.605633, with a leftover of 5.7e-06.
