We divide 642143 by 71
Our goal is to divide 642143 by 71.

On to step 1:
The number 71 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 71

Moving on to step 2:
71 can be fit into 64 0 times, resulting in a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 71

Moving on to step 3:
642 divided by 71 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 639 from 642 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 71

Going ahead to step 4:
71 goes into 31 0 times with a remainder of 31.
The next digit of our result is 0. 
Result so far: 90.0
If we subtract 0 from 31, we get 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 71

Going ahead to step 5:
314 divided by 71 is 4 with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 904.0
Subtracting 284 from 314 leaves us with 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 71

Step 6:
303 divided by 71 is 4 with a remainder of 19.
The next digit of our result is 4. 
Result so far: 9044.0
Deduct 284 from 303 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
190 divided by 71 is 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 9044.2
Subtracting 142 from 190 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
71 can be fit into 480 6 times, resulting in a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 9044.26
Subtract 426 from 480 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
71 can be fit into 540 7 times, resulting in a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 9044.267
Subtracting 497 from 540 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 10:
71 goes into 430 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 9044.2676
If we subtract 426 from 430, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
If we divide 40 by 71, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 9044.2676
If we take 0 away from 40, we end up 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.

Step 12:
400 divided by 71 is 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 9044.267605
Subtract 355 from 400 to 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.

On to step 13:
When dividing 450 by 71, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 9044.2676056
Subtracting 426 from 450 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
If we divide 240 by 71, we get 3 and a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 9044.26760563
Subtract 213 from 240 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 9044.26760563, with a leftover of 2.7e-08.
