126423 ÷ 71 
We're looking to find how many times 71 goes into 126423.

Advancing to step 1:
The number 71 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 71

Advancing to step 2:
If we divide 12 by 71, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 71

Moving on to step 3:
126 divided by 71 is 1 with a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 71 away from 126, we end up with 55.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 71

Advancing to step 4:
The number 71 fits into 554 7 times, leaving a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 497 from 554 and we're left with 57.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 71

Moving on to step 5:
When dividing 572 by 71, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 178.0
Subtract 568 from 572 to get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 71

On to step 6:
If we divide 43 by 71, we get 0 and a remainder of 43.
Record the quotient 0 as the next digit in the result. 
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:
430 divided by 71 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1780.6
If we take 426 away from 430, we end up 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.

Step 8:
If we divide 40 by 71, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1780.6
Deduct 0 from 40 and we're left 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.

Let's proceed to step 9:
When dividing 400 by 71, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 1780.605
Subtracting 355 from 400 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
If we divide 450 by 71, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
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.

Moving on to step 11:
71 can be fit into 240 3 times, resulting in a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 1780.60563
Deduct 213 from 240 and we're left with 27.
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:
270 divided by 71 is 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 1780.605633
Subtract 213 from 270 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Our division results in 1780.605633 with a remaining 5.7e-06.
