Let's divide 71242 by 89
We want to divide 71242 by 89.

Going ahead to step 1:
The number 89 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 89

Moving on to step 2:
89 can be fit into 71 0 times, resulting in a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Append the next digit (2) from the dividend to 71 and continue with: 712 / 89

On to step 3:
712 divided by 89 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 712 from 712 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 89

On to step 4:
89 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 89

On to step 5:
42 divided by 89 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 800.0
If we take 0 away from 42, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 6:
If we divide 420 by 89, we get 4 and a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 800.4
If we take 356 away from 420, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
89 goes into 640 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 800.47
If we take 623 away from 640, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
The number 89 fits into 170 1 times, leaving a remainder of 81.
The next digit of our result is 1. 
Result so far: 800.471
Subtract 89 from 170 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 9:
If we divide 810 by 89, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 800.4719
Subtracting 801 from 810 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
89 goes into 90 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 800.47191
Subtract 89 from 90 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
When dividing 10 by 89, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 800.47191
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
If we divide 100 by 89, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 800.4719101
Subtracting 89 from 100 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 13:
If we divide 110 by 89, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 800.47191011
If we subtract 89 from 110, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 800.47191011 with a remainder of 2.1e-08.
