Let's divide 72250421 by 991
We want to divide 72250421 by 991.

Going ahead to step 1:
7 divided by 991 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 991

Going ahead to step 2:
991 goes into 72 0 times with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Grab the next digit (2) from the dividend, add it to 72, then carry on: 722 / 991

Let's proceed to step 3:
991 can be fit into 722 0 times, resulting in a remainder of 722.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 722, we get 722.
Include the next digit (5) from the dividend after 722, then repeat: 7225 / 991

Going ahead to step 4:
If we divide 7225 by 991, we get 7 and a remainder of 288.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 288 after subtracting 6937 from 7225.
Append the next digit (0) from the dividend to 288 and continue with: 2880 / 991

Moving on to step 5:
If we divide 2880 by 991, we get 2 and a remainder of 898.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 898 after subtracting 1982 from 2880.
Fetch the next digit (4) from the dividend, attach it to 898 and continue: 8984 / 991

On to step 6:
8984 divided by 991 is 9 with a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 729.0
Subtract 8919 from 8984 to get 65.
Fetch the next digit (2) from the dividend, attach it to 65 and continue: 652 / 991

Let's proceed to step 7:
991 goes into 652 0 times with a remainder of 652.
The number 0 becomes the next digit in our result. 
Result so far: 7290.0
Subtracting 0 from 652 leaves us with 652.
Fetch the next digit (1) from the dividend, attach it to 652 and continue: 6521 / 991

Going ahead to step 8:
The number 991 fits into 6521 6 times, leaving a remainder of 575.
Put 6 as the next digit of the answer. 
Result so far: 72906.0
The remainder is 575 after subtracting 5946 from 6521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Step 9:
5750 divided by 991 is 5 with a remainder of 795.
Use 5 as the next digit of our solution. 
Result so far: 72906.5
If we take 4955 away from 5750, we end up with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Advancing to step 10:
The number 991 fits into 7950 8 times, leaving a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 72906.58
The remainder is 22 after subtracting 7928 from 7950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
991 goes into 220 0 times with a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 72906.58
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 12:
2200 divided by 991 is 2 with a remainder of 218.
Put 2 as the next digit of the answer. 
Result so far: 72906.5802
Deduct 1982 from 2200 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 13:
If we divide 2180 by 991, we get 2 and a remainder of 198.
The next digit of our result is 2. 
Result so far: 72906.58022
If we subtract 1982 from 2180, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

The final result is 72906.58022 with a remainder of 0.000198.
