We're dividing 421827 by 81 
We're looking to find how many times 81 goes into 421827.

Advancing to step 1:
The number 81 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 81

Moving on to step 2:
The number 81 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 81

Let's proceed to step 3:
81 can be fit into 421 5 times, resulting in a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 405 away from 421, we end up with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 81

Let's proceed to step 4:
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: 52.0
The remainder is 6 after subtracting 162 from 168.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 81

Moving on to step 5:
The number 81 fits into 62 0 times, leaving a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 520.0
Deduct 0 from 62 and we're left with 62.
Append the next digit (7) from the dividend to 62 and continue with: 627 / 81

Let's proceed to step 6:
627 divided by 81 is 7 with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 5207.0
The remainder is 60 after subtracting 567 from 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
81 goes into 600 7 times with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 5207.7
Subtract 567 from 600 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 8:
If we divide 330 by 81, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 5207.74
If we take 324 away from 330, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
If we divide 60 by 81, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 5207.74
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
The number 81 fits into 600 7 times, leaving a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 5207.7407
Subtracting 567 from 600 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 11:
81 goes into 330 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 5207.74074
If we take 324 away from 330, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
If we divide 60 by 81, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5207.74074
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
If we divide 600 by 81, we get 7 and a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 5207.7407407
Subtract 567 from 600 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 14:
81 goes into 330 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 5207.74074074
The remainder is 6 after subtracting 324 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 5207.74074074 with a remaining 6e-09.
