662122 ÷ 81 
Let's see how many times 81 fits into 662122.

On to step 1:
81 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 81

Let's proceed to step 2:
81 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (2) from the dividend, add it to 66, then carry on: 662 / 81

Going ahead to step 3:
662 divided by 81 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 648 from 662 leaves us with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 81

Advancing to step 4:
When dividing 141 by 81, we get 1 with a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtract 81 from 141 to get 60.
Fetch the next digit (2) from the dividend, attach it to 60 and continue: 602 / 81

Moving on to step 5:
602 divided by 81 is 7 with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 817.0
Deduct 567 from 602 and we're left with 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 81

Step 6:
When dividing 352 by 81, we get 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 8174.0
If we subtract 324 from 352, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
If we divide 280 by 81, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 8174.3
If we take 243 away from 280, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 8:
370 divided by 81 is 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 8174.34
Subtract 324 from 370 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
81 goes into 460 5 times with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 8174.345
Subtract 405 from 460 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
81 can be fit into 550 6 times, resulting in a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 8174.3456
If we take 486 away from 550, 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.

Moving on to step 11:
The number 81 fits into 640 7 times, leaving a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 8174.34567
Subtract 567 from 640 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 12:
The number 81 fits into 730 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 8174.345679
If we subtract 729 from 730, 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 13:
81 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 8174.345679
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
81 goes into 100 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 8174.34567901
If we take 81 away from 100, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 8174.34567901 with a remaining 1.9e-08.
