We divide 669595 by 81
We want to figure out the number of times 669595 can be divided by 81.

Advancing to step 1:
When dividing 6 by 81, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 81

Advancing to step 2:
The number 81 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 81

Going ahead to step 3:
When dividing 669 by 81, we get 8 with a remainder of 21.
The next digit of our result is 8. 
Result so far: 8.0
If we take 648 away from 669, we end up with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 81

Advancing to step 4:
If we divide 215 by 81, we get 2 and a remainder of 53.
The next digit of our result is 2. 
Result so far: 82.0
Deduct 162 from 215 and we're left with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 81

Let's proceed to step 5:
If we divide 539 by 81, we get 6 and a remainder of 53.
The number 6 becomes the next digit in our result. 
Result so far: 826.0
Subtracting 486 from 539 leaves us with 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 81

Let's proceed to step 6:
When dividing 535 by 81, we get 6 with a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 8266.0
Subtract 486 from 535 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
When dividing 490 by 81, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 8266.6
Subtract 486 from 490 to 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.

On to step 8:
81 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8266.6
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.

Going ahead to step 9:
81 can be fit into 400 4 times, resulting in a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 8266.604
If we subtract 324 from 400, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
The number 81 fits into 760 9 times, leaving a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 8266.6049
If we take 729 away from 760, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
310 divided by 81 is 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 8266.60493
The remainder is 67 after subtracting 243 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 12:
If we divide 670 by 81, we get 8 and a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 8266.604938
Subtract 648 from 670 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
220 divided by 81 is 2 with a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 8266.6049382
Subtracting 162 from 220 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 14:
81 goes into 580 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 8266.60493827
If we subtract 567 from 580, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 8266.60493827 and a remainder of 1.3e-08.
