We divide 659923 by 81
Let's see how many times 81 fits into 659923.

Moving on to step 1:
When dividing 6 by 81, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 81

Step 2:
The number 81 fits into 65 0 times, leaving a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 81

Step 3:
If we divide 659 by 81, we get 8 and a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 648 from 659 to get 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 81

Advancing to step 4:
The number 81 fits into 119 1 times, leaving a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Deduct 81 from 119 and we're left with 38.
Append the next digit (2) from the dividend to 38 and continue with: 382 / 81

Advancing to step 5:
81 can be fit into 382 4 times, resulting in a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 814.0
Subtract 324 from 382 to get 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 81

Advancing to step 6:
81 can be fit into 583 7 times, resulting in a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 8147.0
The remainder is 16 after subtracting 567 from 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
If we divide 160 by 81, we get 1 and a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 8147.1
Subtracting 81 from 160 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 8:
When dividing 790 by 81, we get 9 with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 8147.19
Deduct 729 from 790 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
81 can be fit into 610 7 times, resulting in a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 8147.197
Subtract 567 from 610 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 10:
81 goes into 430 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 8147.1975
If we take 405 away from 430, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
If we divide 250 by 81, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 8147.19753
Subtract 243 from 250 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
If we divide 70 by 81, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 8147.19753
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 13:
81 goes into 700 8 times with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 8147.1975308
The remainder is 52 after subtracting 648 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 14:
81 goes into 520 6 times with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 8147.19753086
Deduct 486 from 520 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 8147.19753086 with a remainder of 3.4e-08.
