We're dividing 225989 by 72 
We want to figure out the number of times 225989 can be divided by 72.

Let's proceed to step 1:
When dividing 2 by 72, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 72

Step 2:
72 goes into 22 0 times with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 72

Let's proceed to step 3:
When dividing 225 by 72, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 216 away from 225, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 72

Advancing to step 4:
72 can be fit into 99 1 times, resulting in a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 27 after subtracting 72 from 99.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 72

Going ahead to step 5:
72 can be fit into 278 3 times, resulting in a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 313.0
Deduct 216 from 278 and we're left with 62.
Grab the next digit (9) from the dividend, add it to 62, then carry on: 629 / 72

Let's proceed to step 6:
72 goes into 629 8 times with a remainder of 53.
Use 8 as the next digit of our solution. 
Result so far: 3138.0
If we take 576 away from 629, we end up 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.

Advancing to step 7:
530 divided by 72 is 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 3138.7
If we subtract 504 from 530, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
When dividing 260 by 72, we get 3 with a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 3138.73
If we subtract 216 from 260, 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.

Let's proceed to step 9:
72 can be fit into 440 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 3138.736
Deduct 432 from 440 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.

On to step 10:
72 goes into 80 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 3138.7361
Subtracting 72 from 80 leaves us 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.

Let's proceed to step 11:
When dividing 80 by 72, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 3138.73611
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 3138.73611, with a leftover of 8e-06.
