407413 ÷ 90 
We want to divide 407413 by 90.

Let's proceed to step 1:
90 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 90

Let's proceed to step 2:
If we divide 40 by 90, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 90

On to step 3:
90 goes into 407 4 times with a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 360 away from 407, we end up with 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 90

Moving on to step 4:
The number 90 fits into 474 5 times, leaving a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 45.0
The remainder is 24 after subtracting 450 from 474.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 90

Going ahead to step 5:
When dividing 241 by 90, we get 2 with a remainder of 61.
Use 2 as the next digit of our solution. 
Result so far: 452.0
Subtracting 180 from 241 leaves us with 61.
Include the next digit (3) from the dividend after 61, then repeat: 613 / 90

Going ahead to step 6:
When dividing 613 by 90, we get 6 with a remainder of 73.
Record the quotient 6 as the next digit in the result. 
Result so far: 4526.0
Subtract 540 from 613 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 7:
730 divided by 90 is 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 4526.8
Subtracting 720 from 730 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 90, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 4526.81
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
If we divide 100 by 90, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 4526.811
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 4526.811, with a leftover of 0.001.
