We look at the division of 71124560 by 642 
Let's see how many times 642 fits into 71124560.

Going ahead to step 1:
642 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 642

Step 2:
The number 642 fits into 71 0 times, leaving a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Bring next digit (1) of the dividend behind the 71 and repeat the process: 711 / 642

Let's proceed to step 3:
When dividing 711 by 642, we get 1 with a remainder of 69.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 642 from 711, we get 69.
Fetch the next digit (2) from the dividend, attach it to 69 and continue: 692 / 642

Moving on to step 4:
When dividing 692 by 642, we get 1 with a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 642 away from 692, we end up with 50.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 642

On to step 5:
642 goes into 504 0 times with a remainder of 504.
The next digit of our result is 0. 
Result so far: 110.0
The remainder is 504 after subtracting 0 from 504.
Grab the next digit (5) from the dividend, add it to 504, then carry on: 5045 / 642

Let's proceed to step 6:
642 can be fit into 5045 7 times, resulting in a remainder of 551.
The next digit of our result is 7. 
Result so far: 1107.0
Subtracting 4494 from 5045 leaves us with 551.
Take the next digit (6) from the dividend and append it to 551, then repeat: 5516 / 642

Let's proceed to step 7:
5516 divided by 642 is 8 with a remainder of 380.
The next digit of our result is 8. 
Result so far: 11078.0
If we subtract 5136 from 5516, we get 380.
Grab the next digit (0) from the dividend, add it to 380, then carry on: 3800 / 642

Going ahead to step 8:
3800 divided by 642 is 5 with a remainder of 590.
Use 5 as the next digit of our solution. 
Result so far: 110785.0
If we take 3210 away from 3800, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 9:
When dividing 5900 by 642, we get 9 with a remainder of 122.
The next digit of our result is 9. 
Result so far: 110785.9
Subtract 5778 from 5900 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 10:
If we divide 1220 by 642, we get 1 and a remainder of 578.
The next digit of our result is 1. 
Result so far: 110785.91
Deduct 642 from 1220 and we're left with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

On to step 11:
When dividing 5780 by 642, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 110785.919
Subtracting 5778 from 5780 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
The number 642 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 110785.919
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
When dividing 200 by 642, we get 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 110785.919
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 110785.919, with a leftover of 0.0002.
