We divide 438646 by 81
Our goal is to divide 438646 by 81.

Step 1:
81 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 81

Advancing to step 2:
The number 81 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 81

Moving on to step 3:
If we divide 438 by 81, we get 5 and a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 405 from 438 leaves us with 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 81

Moving on to step 4:
The number 81 fits into 336 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 54.0
If we take 324 away from 336, we end up with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 81

Step 5:
81 can be fit into 124 1 times, resulting in a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 541.0
Subtracting 81 from 124 leaves us with 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 81

Step 6:
81 goes into 436 5 times with a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 5415.0
Subtracting 405 from 436 leaves us 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.

Moving on to step 7:
When dividing 310 by 81, we get 3 with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 5415.3
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.

Step 8:
81 goes into 670 8 times with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 5415.38
If we take 648 away from 670, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
81 can be fit into 220 2 times, resulting in a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 5415.382
If we subtract 162 from 220, we 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.

Moving on to step 10:
81 goes into 580 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 5415.3827
Deduct 567 from 580 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
130 divided by 81 is 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 5415.38271
Subtracting 81 from 130 leaves us 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.

Advancing to step 12:
81 goes into 490 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 5415.382716
If we take 486 away from 490, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
81 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 5415.382716
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
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: 5415.38271604
Subtract 324 from 400 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 5415.38271604 with a balance of 7.6e-08.
