We divide 15958225 by 72
Let's see how many times 72 fits into 15958225.

Let's proceed to step 1:
When dividing 1 by 72, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 72

On to step 2:
72 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 72

Going ahead to step 3:
72 goes into 159 2 times with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 144 away from 159, we end up with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 72

Step 4:
If we divide 155 by 72, we get 2 and a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 22.0
Deduct 144 from 155 and we're left with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 72

Going ahead to step 5:
72 can be fit into 118 1 times, resulting in a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 221.0
Subtracting 72 from 118 leaves us with 46.
Take the next digit (2) from the dividend and append it to 46, then repeat: 462 / 72

Moving on to step 6:
462 divided by 72 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 2216.0
Subtract 432 from 462 to get 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 72

Advancing to step 7:
72 goes into 302 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 22164.0
Subtracting 288 from 302 leaves us with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 72

Step 8:
145 divided by 72 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 221642.0
Subtract 144 from 145 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
72 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 221642.0
Deduct 0 from 10 and we're left 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.

Step 10:
72 goes into 100 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 221642.01
If we take 72 away from 100, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
When dividing 280 by 72, we get 3 with a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 221642.013
Deduct 216 from 280 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 221642.0138
Subtracting 576 from 640 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 13:
When dividing 640 by 72, we get 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 221642.01388
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 221642.01388 with a remainder of 6.4e-05.
