We look at the division of 991910 by 72 
Let's see how many times 72 fits into 991910.

Step 1:
9 divided by 72 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 72

Let's proceed to step 2:
The number 72 fits into 99 1 times, leaving a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 72 from 99 and we're left with 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 72

Moving on to step 3:
271 divided by 72 is 3 with a remainder of 55.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 216 from 271 to get 55.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 72

Advancing to step 4:
72 can be fit into 559 7 times, resulting in a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
If we subtract 504 from 559, we get 55.
Take the next digit (1) from the dividend and append it to 55, then repeat: 551 / 72

Step 5:
72 goes into 551 7 times with a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 1377.0
If we subtract 504 from 551, we get 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 72

Advancing to step 6:
If we divide 470 by 72, we get 6 and a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 13776.0
Subtract 432 from 470 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
72 goes into 380 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 13776.5
Subtract 360 from 380 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
72 goes into 200 2 times with a remainder of 56.
The next digit of our result is 2. 
Result so far: 13776.52
If we take 144 away from 200, we end up with 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 9:
72 can be fit into 560 7 times, resulting in a remainder of 56.
The next digit of our result is 7. 
Result so far: 13776.527
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 10:
72 goes into 560 7 times with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 13776.5277
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.

Our division results in 13776.5277 with a remaining 0.00056.
