Let's divide 438407 by 81
We want to figure out the number of times 438407 can be divided by 81.

Moving on to step 1:
4 divided by 81 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 81

Step 2:
81 can be fit into 43 0 times, resulting in a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 81

Moving on to step 3:
438 divided by 81 is 5 with a remainder of 33.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 33 after subtracting 405 from 438.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 81

Going ahead to step 4:
81 can be fit into 334 4 times, resulting in a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
If we subtract 324 from 334, we get 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 81

Moving on to step 5:
When dividing 100 by 81, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 541.0
Subtract 81 from 100 to get 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 81

Step 6:
When dividing 197 by 81, we get 2 with a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 5412.0
Subtract 162 from 197 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
When dividing 350 by 81, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 5412.4
Subtracting 324 from 350 leaves us 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.

Moving on to step 8:
81 goes into 260 3 times with a remainder of 17.
The next digit of our result is 3. 
Result so far: 5412.43
If we take 243 away from 260, we end up 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.

On to step 9:
The number 81 fits into 170 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 5412.432
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
If we divide 80 by 81, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 5412.432
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
If we divide 800 by 81, we get 9 and a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 5412.43209
If we subtract 729 from 800, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 12:
81 goes into 710 8 times with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 5412.432098
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.

Going ahead to step 13:
If we divide 620 by 81, we get 7 and a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 5412.4320987
Subtracting 567 from 620 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 14:
If we divide 530 by 81, we get 6 and a remainder of 44.
The next digit of our result is 6. 
Result so far: 5412.43209876
If we subtract 486 from 530, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 5412.43209876 and a remainder of 4.4e-08.
