978472 divided by 81 
We want to figure out the number of times 978472 can be divided by 81.

Going ahead to step 1:
9 divided by 81 is 0 with 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.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 81

On to step 2:
81 goes into 97 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 81 away from 97, we end up with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 81

Going ahead to step 3:
The number 81 fits into 168 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 162 from 168 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 81

Going ahead to step 4:
81 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 120.0
If we subtract 0 from 64, we get 64.
Include the next digit (7) from the dividend after 64, then repeat: 647 / 81

Advancing to step 5:
647 divided by 81 is 7 with a remainder of 80.
Record the quotient 7 as the next digit in the result. 
Result so far: 1207.0
Deduct 567 from 647 and we're left with 80.
Grab the next digit (2) from the dividend, add it to 80, then carry on: 802 / 81

Let's proceed to step 6:
If we divide 802 by 81, we get 9 and a remainder of 73.
The next digit of our result is 9. 
Result so far: 12079.0
Deduct 729 from 802 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.

Moving on to step 7:
When dividing 730 by 81, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 12079.9
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 8:
81 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12079.9
Deduct 0 from 10 and we're left 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.

Advancing to step 9:
If we divide 100 by 81, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 12079.901
Subtract 81 from 100 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
If we divide 190 by 81, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 12079.9012
Subtracting 162 from 190 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
When dividing 280 by 81, we get 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 12079.90123
The remainder is 37 after subtracting 243 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 12:
370 divided by 81 is 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 12079.901234
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.

Let's proceed to step 13:
81 goes into 460 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 12079.9012345
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.

Moving on to step 14:
When dividing 550 by 81, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 12079.90123456
The remainder is 64 after subtracting 486 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 12079.90123456 with a remaining 6.4e-08.
