Let's divide 81521865 by 219
Our goal is to divide 81521865 by 219.

Step 1:
The number 219 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 219

Let's proceed to step 2:
When dividing 81 by 219, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 219

Let's proceed to step 3:
219 can be fit into 815 3 times, resulting in a remainder of 158.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 657 from 815 and we're left with 158.
Bring next digit (2) of the dividend behind the 158 and repeat the process: 1582 / 219

Let's proceed to step 4:
The number 219 fits into 1582 7 times, leaving a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtracting 1533 from 1582 leaves us with 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 219

Moving on to step 5:
When dividing 491 by 219, we get 2 with a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 372.0
Subtract 438 from 491 to get 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 219

Going ahead to step 6:
If we divide 538 by 219, we get 2 and a remainder of 100.
Write down 2 as next digit of the result. 
Result so far: 3722.0
If we take 438 away from 538, we end up with 100.
Fetch the next digit (6) from the dividend, attach it to 100 and continue: 1006 / 219

Advancing to step 7:
The number 219 fits into 1006 4 times, leaving a remainder of 130.
The number 4 becomes the next digit in our result. 
Result so far: 37224.0
Deduct 876 from 1006 and we're left with 130.
Bring next digit (5) of the dividend behind the 130 and repeat the process: 1305 / 219

Going ahead to step 8:
If we divide 1305 by 219, we get 5 and a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 372245.0
If we subtract 1095 from 1305, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 9:
219 can be fit into 2100 9 times, resulting in a remainder of 129.
Record the quotient 9 as the next digit in the result. 
Result so far: 372245.9
The remainder is 129 after subtracting 1971 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 10:
1290 divided by 219 is 5 with a remainder of 195.
Write down 5 as next digit of the result. 
Result so far: 372245.95
If we take 1095 away from 1290, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 11:
The number 219 fits into 1950 8 times, leaving a remainder of 198.
Put 8 as the next digit of the answer. 
Result so far: 372245.958
Subtract 1752 from 1950 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 12:
The number 219 fits into 1980 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 372245.9589
Subtracting 1971 from 1980 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
The number 219 fits into 90 0 times, leaving a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 372245.9589
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 14:
The number 219 fits into 900 4 times, leaving a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 372245.958904
Subtract 876 from 900 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 15:
The number 219 fits into 240 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 372245.9589041
The remainder is 21 after subtracting 219 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 16:
219 goes into 210 0 times with a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 372245.9589041
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Our division results in 372245.9589041 with a remaining 2.1e-07.
