Let's divide 658245 by 81
We want to divide 658245 by 81.

Going ahead to step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 81

Going ahead to step 2:
When dividing 65 by 81, we get 0 with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 81

Going ahead to step 3:
658 divided by 81 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 648 from 658 to get 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 81

Going ahead to step 4:
If we divide 102 by 81, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 81.0
If we take 81 away from 102, we end up with 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 81

Going ahead to step 5:
214 divided by 81 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 812.0
The remainder is 52 after subtracting 162 from 214.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 81

Going ahead to step 6:
When dividing 525 by 81, we get 6 with a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 8126.0
If we subtract 486 from 525, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
When dividing 390 by 81, we get 4 with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 8126.4
If we take 324 away from 390, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
The number 81 fits into 660 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 8126.48
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
81 goes into 120 1 times with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 8126.481
Subtract 81 from 120 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 10:
If we divide 390 by 81, we get 4 and a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 8126.4814
If we take 324 away from 390, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 11:
81 can be fit into 660 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 8126.48148
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
81 goes into 120 1 times with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 8126.481481
Subtract 81 from 120 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 13:
The number 81 fits into 390 4 times, leaving a remainder of 66.
The next digit of our result is 4. 
Result so far: 8126.4814814
Subtract 324 from 390 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 14:
If we divide 660 by 81, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 8126.48148148
Subtract 648 from 660 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 8126.48148148 with a remaining 1.2e-08.
