We're dividing 712810 by 89 
We're looking to find how many times 89 goes into 712810.

Advancing to step 1:
7 divided by 89 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 89

On to step 2:
When dividing 71 by 89, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 89

Let's proceed to step 3:
If we divide 712 by 89, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 712 from 712 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 89

Going ahead to step 4:
89 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 80.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 89

Advancing to step 5:
81 divided by 89 is 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 800.0
Subtract 0 from 81 to get 81.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 89

Going ahead to step 6:
89 goes into 810 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 8009.0
If we take 801 away from 810, we end up 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.

Step 7:
When dividing 90 by 89, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 8009.1
If we subtract 89 from 90, we 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.

Moving on to step 8:
The number 89 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 8009.1
If we subtract 0 from 10, we 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.

On to step 9:
The number 89 fits into 100 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 8009.101
Subtract 89 from 100 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
If we divide 110 by 89, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 8009.1011
Deduct 89 from 110 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 8009.1011 with a remaining 0.00021.
