906661 ÷ 81 
We're looking to find how many times 81 goes into 906661.

Moving on to step 1:
81 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 81

Step 2:
The number 81 fits into 90 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 81 from 90 and we're left with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 81

Step 3:
81 can be fit into 96 1 times, resulting in a remainder of 15.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 15 after subtracting 81 from 96.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 81

Moving on to step 4:
The number 81 fits into 156 1 times, leaving a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 111.0
If we take 81 away from 156, we end up with 75.
Append the next digit (6) from the dividend to 75 and continue with: 756 / 81

Advancing to step 5:
If we divide 756 by 81, we get 9 and a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 1119.0
Subtract 729 from 756 to get 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 81

Let's proceed to step 6:
When dividing 271 by 81, we get 3 with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 11193.0
Subtract 243 from 271 to 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.
The next digit of our result is 3. 
Result so far: 11193.3
If we subtract 243 from 280, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
When dividing 370 by 81, we get 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 11193.34
If we take 324 away from 370, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
When dividing 460 by 81, we get 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 11193.345
Deduct 405 from 460 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
81 goes into 550 6 times with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 11193.3456
Subtract 486 from 550 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
640 divided by 81 is 7 with a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 11193.34567
Deduct 567 from 640 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 12:
The number 81 fits into 730 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 11193.345679
Subtracting 729 from 730 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
When dividing 10 by 81, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 11193.345679
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.

Advancing to step 14:
If we divide 100 by 81, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 11193.34567901
Subtracting 81 from 100 leaves us 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.

After the division, we end up with 11193.34567901 and a remainder of 1.9e-08.
