290405 ÷ 72 
We want to figure out the number of times 290405 can be divided by 72.

Moving on to step 1:
When dividing 2 by 72, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 72

On to step 2:
72 can be fit into 29 0 times, resulting in a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 72

On to step 3:
The number 72 fits into 290 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 288 from 290 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 72

Let's proceed to step 4:
When dividing 24 by 72, we get 0 with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 24, we end up with 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 72

Let's proceed to step 5:
When dividing 240 by 72, we get 3 with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 403.0
If we take 216 away from 240, we end up with 24.
Include the next digit (5) from the dividend after 24, then repeat: 245 / 72

Moving on to step 6:
When dividing 245 by 72, we get 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 4033.0
If we take 216 away from 245, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
When dividing 290 by 72, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4033.4
Deduct 288 from 290 and we're left 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.

Moving on to step 8:
If we divide 20 by 72, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4033.4
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
200 divided by 72 is 2 with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 4033.402
Subtract 144 from 200 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
When dividing 560 by 72, we get 7 with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 4033.4027
Subtract 504 from 560 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
72 goes into 560 7 times with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 4033.40277
If we subtract 504 from 560, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 4033.40277, with a leftover of 5.6e-05.
