72057189 ÷ 991 
Let's see how many times 991 fits into 72057189.

Going ahead to step 1:
7 divided by 991 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 991

Advancing to step 2:
72 divided by 991 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 991

Going ahead to step 3:
991 can be fit into 720 0 times, resulting in a remainder of 720.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 720 to get 720.
Include the next digit (5) from the dividend after 720, then repeat: 7205 / 991

Let's proceed to step 4:
If we divide 7205 by 991, we get 7 and a remainder of 268.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 6937 from 7205, we get 268.
Bring next digit (7) of the dividend behind the 268 and repeat the process: 2687 / 991

Moving on to step 5:
The number 991 fits into 2687 2 times, leaving a remainder of 705.
The next digit of our result is 2. 
Result so far: 72.0
Subtract 1982 from 2687 to get 705.
Take the next digit (1) from the dividend and append it to 705, then repeat: 7051 / 991

Step 6:
The number 991 fits into 7051 7 times, leaving a remainder of 114.
Record the quotient 7 as the next digit in the result. 
Result so far: 727.0
Deduct 6937 from 7051 and we're left with 114.
Bring next digit (8) of the dividend behind the 114 and repeat the process: 1148 / 991

Step 7:
If we divide 1148 by 991, we get 1 and a remainder of 157.
Record the quotient 1 as the next digit in the result. 
Result so far: 7271.0
If we take 991 away from 1148, we end up with 157.
Take the next digit (9) from the dividend and append it to 157, then repeat: 1579 / 991

On to step 8:
991 can be fit into 1579 1 times, resulting in a remainder of 588.
The number 1 becomes the next digit in our result. 
Result so far: 72711.0
Subtracting 991 from 1579 leaves us with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Going ahead to step 9:
991 goes into 5880 5 times with a remainder of 925.
Use 5 as the next digit of our solution. 
Result so far: 72711.5
Subtract 4955 from 5880 to get 925.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9250, and continue the process.

Going ahead to step 10:
The number 991 fits into 9250 9 times, leaving a remainder of 331.
The next digit of our result is 9. 
Result so far: 72711.59
Subtracting 8919 from 9250 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Let's proceed to step 11:
991 can be fit into 3310 3 times, resulting in a remainder of 337.
The number 3 becomes the next digit in our result. 
Result so far: 72711.593
If we subtract 2973 from 3310, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Let's proceed to step 12:
3370 divided by 991 is 3 with a remainder of 397.
Write down 3 as next digit of the result. 
Result so far: 72711.5933
Deduct 2973 from 3370 and we're left with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Our division results in 72711.5933 with a remaining 0.00397.
