We're dividing 961839 by 72 
We want to divide 961839 by 72.

On to step 1:
9 divided by 72 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 72

Step 2:
72 can be fit into 96 1 times, resulting in a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 72 away from 96, we end up with 24.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 72

On to step 3:
241 divided by 72 is 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 216 from 241 leaves us with 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 72

Step 4:
72 can be fit into 258 3 times, resulting in a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 133.0
If we subtract 216 from 258, we get 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 72

Let's proceed to step 5:
When dividing 423 by 72, we get 5 with a remainder of 63.
Use 5 as the next digit of our solution. 
Result so far: 1335.0
If we subtract 360 from 423, we get 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 72

On to step 6:
72 can be fit into 639 8 times, resulting in a remainder of 63.
Put 8 as the next digit of the answer. 
Result so far: 13358.0
Deduct 576 from 639 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 7:
If we divide 630 by 72, we get 8 and a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 13358.8
Deduct 576 from 630 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
When dividing 540 by 72, we get 7 with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 13358.87
If we subtract 504 from 540, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
72 goes into 360 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 13358.875
Subtracting 360 from 360 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
When dividing 0 by 72, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13358.875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
72 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 13358.875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 13358.875, and the remainder is 0.0.
