Let's divide 219919 by 81
We want to figure out the number of times 219919 can be divided by 81.

On to step 1:
81 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 81

Advancing to step 2:
When dividing 21 by 81, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 81

Advancing to step 3:
81 goes into 219 2 times with a remainder of 57.
The next digit of our result is 2. 
Result so far: 2.0
If we take 162 away from 219, we end up with 57.
Grab the next digit (9) from the dividend, add it to 57, then carry on: 579 / 81

Going ahead to step 4:
579 divided by 81 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 567 from 579 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 81

Step 5:
The number 81 fits into 121 1 times, leaving a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 271.0
If we subtract 81 from 121, we get 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 81

Going ahead to step 6:
If we divide 409 by 81, we get 5 and a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 2715.0
The remainder is 4 after subtracting 405 from 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
If we divide 40 by 81, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 2715.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
The number 81 fits into 400 4 times, leaving a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 2715.04
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 9:
If we divide 760 by 81, we get 9 and a remainder of 31.
The next digit of our result is 9. 
Result so far: 2715.049
If we take 729 away from 760, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
The number 81 fits into 310 3 times, leaving a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 2715.0493
Deduct 243 from 310 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 11:
The number 81 fits into 670 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 2715.04938
The remainder is 22 after subtracting 648 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
When dividing 220 by 81, we get 2 with a remainder of 58.
The next digit of our result is 2. 
Result so far: 2715.049382
Subtract 162 from 220 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 13:
If we divide 580 by 81, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 2715.0493827
If we subtract 567 from 580, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 14:
81 can be fit into 130 1 times, resulting in a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 2715.04938271
Deduct 81 from 130 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 2715.04938271 and a remainder of 4.9e-08.
