We look at the division of 72609961 by 836 
We want to figure out the number of times 72609961 can be divided by 836.

Moving on to step 1:
The number 836 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 836

Step 2:
836 can be fit into 72 0 times, resulting in a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Include the next digit (6) from the dividend after 72, then repeat: 726 / 836

Step 3:
If we divide 726 by 836, we get 0 and a remainder of 726.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 726 and we're left with 726.
Append the next digit (0) from the dividend to 726 and continue with: 7260 / 836

Moving on to step 4:
When dividing 7260 by 836, we get 8 with a remainder of 572.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 572 after subtracting 6688 from 7260.
Append the next digit (9) from the dividend to 572 and continue with: 5729 / 836

Step 5:
5729 divided by 836 is 6 with a remainder of 713.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtract 5016 from 5729 to get 713.
Include the next digit (9) from the dividend after 713, then repeat: 7139 / 836

Advancing to step 6:
7139 divided by 836 is 8 with a remainder of 451.
Put 8 as the next digit of the answer. 
Result so far: 868.0
Subtracting 6688 from 7139 leaves us with 451.
Take the next digit (6) from the dividend and append it to 451, then repeat: 4516 / 836

Step 7:
If we divide 4516 by 836, we get 5 and a remainder of 336.
The number 5 becomes the next digit in our result. 
Result so far: 8685.0
Subtracting 4180 from 4516 leaves us with 336.
Bring next digit (1) of the dividend behind the 336 and repeat the process: 3361 / 836

Let's proceed to step 8:
3361 divided by 836 is 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 86854.0
If we subtract 3344 from 3361, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
170 divided by 836 is 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 86854.0
Subtract 0 from 170 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
When dividing 1700 by 836, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 86854.02
Subtract 1672 from 1700 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
The number 836 fits into 280 0 times, leaving a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 86854.02
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
836 goes into 2800 3 times with a remainder of 292.
Record the quotient 3 as the next digit in the result. 
Result so far: 86854.0203
Subtract 2508 from 2800 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 13:
The number 836 fits into 2920 3 times, leaving a remainder of 412.
The number 3 becomes the next digit in our result. 
Result so far: 86854.02033
If we take 2508 away from 2920, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

The quotient of the division is 86854.02033, and the remainder is 0.000412.
