Let's divide 415574 by 81
We want to divide 415574 by 81.

Moving on to step 1:
The number 81 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 81

Step 2:
41 divided by 81 is 0 with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Append the next digit (5) from the dividend to 41 and continue with: 415 / 81

Step 3:
81 goes into 415 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 405 away from 415, we end up with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 81

Moving on to step 4:
When dividing 105 by 81, we get 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtracting 81 from 105 leaves us with 24.
Grab the next digit (7) from the dividend, add it to 24, then carry on: 247 / 81

Step 5:
81 can be fit into 247 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 513.0
The remainder is 4 after subtracting 243 from 247.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 81

Advancing to step 6:
44 divided by 81 is 0 with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 5130.0
If we take 0 away from 44, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
81 goes into 440 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 5130.5
Deduct 405 from 440 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
81 can be fit into 350 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 5130.54
Deduct 324 from 350 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
81 can be fit into 260 3 times, resulting in a remainder of 17.
The next digit of our result is 3. 
Result so far: 5130.543
Subtracting 243 from 260 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
When dividing 170 by 81, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 5130.5432
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
The number 81 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 5130.5432
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
When dividing 800 by 81, we get 9 with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 5130.543209
If we take 729 away from 800, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 13:
The number 81 fits into 710 8 times, leaving a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 5130.5432098
Subtracting 648 from 710 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
81 can be fit into 620 7 times, resulting in a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 5130.54320987
Subtract 567 from 620 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

After the division, we end up with 5130.54320987 and a remainder of 5.3e-08.
