We divide 939972 by 81
We're looking to find how many times 81 goes into 939972.

Moving on to step 1:
9 divided by 81 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 81

Moving on to step 2:
The number 81 fits into 93 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 81 from 93 and we're left with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 81

Advancing to step 3:
If we divide 129 by 81, we get 1 and a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 81 away from 129, we end up with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 81

Advancing to step 4:
81 goes into 489 6 times with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Deduct 486 from 489 and we're left with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 81

Moving on to step 5:
37 divided by 81 is 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 1160.0
Subtract 0 from 37 to get 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 81

On to step 6:
372 divided by 81 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 11604.0
If we take 324 away from 372, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
If we divide 480 by 81, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 11604.5
Deduct 405 from 480 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 8:
The number 81 fits into 750 9 times, leaving a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 11604.59
If we take 729 away from 750, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
81 goes into 210 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 11604.592
Subtracting 162 from 210 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
When dividing 480 by 81, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 11604.5925
Subtracting 405 from 480 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
81 can be fit into 750 9 times, resulting in a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 11604.59259
Subtracting 729 from 750 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
The number 81 fits into 210 2 times, leaving a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 11604.592592
Subtract 162 from 210 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
81 goes into 480 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 11604.5925925
Subtracting 405 from 480 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 14:
When dividing 750 by 81, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 11604.59259259
The remainder is 21 after subtracting 729 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 11604.59259259 and a remainder of 2.1e-08.
