We're dividing 407090 by 81 
We're looking to find how many times 81 goes into 407090.

On to step 1:
The number 81 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 81

Step 2:
81 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 81

Advancing to step 3:
81 goes into 407 5 times with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 405 away from 407, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 81

Step 4:
81 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 81

Advancing to step 5:
81 goes into 209 2 times with a remainder of 47.
Record the quotient 2 as the next digit in the result. 
Result so far: 502.0
If we take 162 away from 209, we end up with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 81

Going ahead to step 6:
81 goes into 470 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 5025.0
The remainder is 65 after subtracting 405 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
81 can be fit into 650 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 5025.8
If we take 648 away from 650, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
If we divide 20 by 81, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 5025.8
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
81 can be fit into 200 2 times, resulting in a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 5025.802
If we subtract 162 from 200, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
81 goes into 380 4 times with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 5025.8024
If we take 324 away from 380, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
81 can be fit into 560 6 times, resulting in a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 5025.80246
The remainder is 74 after subtracting 486 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 12:
The number 81 fits into 740 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 5025.802469
Subtract 729 from 740 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
When dividing 110 by 81, we get 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 5025.8024691
If we subtract 81 from 110, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 14:
When dividing 290 by 81, we get 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 5025.80246913
Deduct 243 from 290 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The quotient of the division is 5025.80246913, and the remainder is 4.7e-08.
